Abstract
BACKGROUND Skin photoaging and uneven pigmentation are common dermatological concerns. Tetrahexyldecyl ascorbate (THDA) and acetyl zingerone (AZ) are potent antioxidants that have been shown to have anti-photoaging and anti-pigmentation effects. THDA is a more stable and penetrable form of vitamin C. AZ is an antioxidant derived from ginger which has clinical evidence for improving photoaging. However, no studies have assessed how they may synergistically act on the skin. AIMS This study aims to assess whether a serum containing both THDA and AZ can improve photoaging and the appearance of uneven facial pigmentation. PATIENTS/METHODS This open-label study was conducted on 35 healthy individuals aged 21-55. All subjects were instructed to use three to five drops of the topical serum (Power-C Serum, Image Skincare, Lantana, FL) daily for 12 weeks. Videomicroscopy and high-resolution photography and various skin biophysical measurements were taken at baseline, 1, 4, and 12 weeks. Outcomes included skin tone and pigmentation, transepidermal water loss (TEWL), skin smoothness, firmness, and elasticity. RESULTS Compared to baseline, the results at 12 weeks revealed significant decreases in skin pigmentation (p < 0.0001), decreased fine lines and wrinkles (p < 0.0001), and increased smoothness (p < 0.0001), firmness (p < 0.0001), and elasticity (p < 0.0001). Additionally, transepidermal water loss was significantly decreased at 4 weeks compared to baseline (p = 0.01), indicating an increased epidermal barrier integrity. CONCLUSIONS Overall, these findings provide evidence for the combined use of THDA and AZ to address skin photoaging and dyspigmentation changes.

Abstract
BACKGROUND Tetrahexydecyl ascorbate (THDA) is a lipophilic precursor to ascorbic acid that may be stabilized by acetyl zingerone (AZ). Studies have shown that the topical application of THDA may have photoprotective effects. Similarly, AZ has been shown to mitigate oxidative and inflammatory stress, thereby improving the appearance of photoaging. AIMS To examine the effects of THDA and AZ (THDA-AZ) on skin photoaging compared to THDA alone. PATIENTS/METHODS In this double-blind, randomized controlled trial, healthy individuals aged 30 to 65 were included and 44 participants were randomized to receive either THDA-AZ (THDA 5% + AZ 1%) or THDA only (THDA 5%) for 8 weeks. Facial photographs were taken at 0, 4, and 8 weeks to analyze wrinkle severity, pigment intensity, and redness intensity. A skin colorimeter was used to assess infraorbital pigmentation and erythema. Self-perception of skin and tolerability were assessed through questionnaires. RESULTS Average wrinkle severity was significantly decreased in the THDA-AZ group at Weeks 4 and 8 by 0.75% (p = 0.023) and 3.72% (p = 0.048), respectively, compared to the THDA group where wrinkle severity at Weeks 4 and 8 was increased by 7.88% and 4.48%, respectively. Facial pigment intensity was significantly decreased in the THDA-AZ group by 4.10% (p = 0.0002) at Week 8 compared to a 0.69% decrease in the THDA group. Facial redness intensity was decreased in the THDA-AZ group at Weeks 4 and 8 by 3.73% (p = 0.0162) and 14.25% (p = 0.045), respectively, compared to the THDA group where at Weeks 4 and 8 erythema increased by 27.5% and 8.34%, respectively. There were no significant differences in either group for infraorbital pigmentation or erythema. CONCLUSIONS Daily use of combined THDA and AZ may improve facial wrinkle severity, pigment intensity, and erythema to a greater extent than THDA. While THDA alone increases facial wrinkle severity and erythema, the addition of AZ reduces both.

Abstract
Background: Preliminary studies support the use of topical coconut and sunflower seed oil for atopic dermatitis (AD). However, standardized topical formulations of fatty acids from these sources have not been studied. Objective: This study investigates whether coconut oil- and sunflower seed oil-derived isosorbide diesters can be used in conjunction with colloidal oatmeal to improve itch, AD severity, and the need for topical steroids in adults. Methods: This was a single-center, 4-week, randomized, double-blind, and vehicle-controlled study conducted between 2021 and 2022. Thirty-two male and female adults with mild-to-moderate AD were enrolled and completed the study. Participants were randomized to receive either 0.1% colloidal oatmeal (vehicle) or isosorbide diesters (IDEAS, 4% isosorbide dicaprylate and 4% isosorbide disunflowerseedate) along with 0.1% colloidal oatmeal. The main outcomes of the study were changes in the visual analogue rating of itch and 75% improvement in the Eczema Area and Severity Index score (EASI 75) at 4 weeks. Other measures included the use of topical steroids and the relative abundance of skin Staphylococcus aureus. Results: Participants in the IDEAS group had a 65.6% improvement in itch compared with 43.8% in the vehicle group (P = 0.013). In total, 56.5% and 25% of the those in the IDEAS and vehicle groups, respectively, achieved EASI 75 at 4 weeks (P = 0.07). There was no difference in skin hydration or transepidermal water loss. The relative abundance of S. aureus was decreased in the IDEAS group at week 4 compared with no change in the vehicle group (P = 0.044). Topical corticosteroid use increased in the vehicle group compared with a decrease in the IDEAS group at week 1 (292.5% vs 24.8%; P value = 0.039) and week 2 (220% vs 46%; P value = 0.08). Conclusions: Topical application of emollients containing coconut oil- and sunflower seed oil-derived fatty esters may improve itch, reduce topical steroid use, and reduce the relative abundance of S. aureus in mild-to-moderate AD. CTR number: NCT04831892.

Abstract
Punica granatum L., commonly known as the pomegranate, is an abundant source of polyphenols, including hydrolyzable ellagitannins, ellagic acid, anthocyanins, and other bioactive phytochemicals shown to be effective in defending against oxidative stress, and has immunomodulatory activities. Ellagitannins, and their hydrolyzed product ellagic acid, interact with the gut microbiota to yield secondary metabolites known as urolithins that may have health benefits. The objective of this study was to determine the effects of supplementation with a standardized punicalagin-enriched pomegranate extract, Pomella® (250 mg), on the gut microbiome, circulating short-chain fatty acids, and gut microbial-derived ellagitannin metabolite urolithins. A randomized, double-blind, placebo-controlled study was conducted over 4 weeks on healthy volunteers aged 25-55 years. Subjects were randomly assigned to receive either an oral supplement containing 75 mg of punicalagin or an oral placebo. Stool sample collection and venipuncture were performed to analyze the gut microbiome, SCFAs, and urolithin. There was no significant change in the gut microbial diversity in both cohorts after 4 weeks of intervention, but there was a significantly increased relative abundance of Coprococcus eutectus, Roseburia faecis, Roseburia inullnivorans, Ruminococcus bicirculans, Ruminococcus calidus, and Faecalibacterium prausnitzii. Pomegranate extract (PE) supplementation led to the augmentation of circulating propionate levels (p = 0.02) and an increasing trend for acetate levels (p = 0.12). The pomegranate extract (PE) supplementation group had an increased level of circulating urolithins compared to the placebo group (6.6% vs. 1.1%, p = 0.13). PE supplementation correlated with shifts in the gut microbiome and with higher circulating levels of propionate and acetate. Further studies should explore the implications in larger cohorts and over a longer duration.

Abstract
Objective This review examines the current literature on the gut-skin connection in alopecia and summarizes interventions that impact hair growth by modulation of the gut or skin microbiome. Methods PubMed searches were done to assess studies of the gut and skin microbiome and forms of alopecia including, alopecia areata (AA), androgenic alopecia (AGA), alopecia universalis (AU), central centrifugal cicatricial alopecia (CCCA) and lichen planopilaris (LPP). Filters were applied for human and animal studies. Articles not translated to English and studies assessing supplemental therapies on alopecia were excluded. Results There is evidence that scalp, hair follicle, and gut microbiome alterations are associated with various types of alopecia. There is potential in the use of interventions targeting microbiome dysbiosis, including fecal transplants and probiotics. Limitations This field of study still requires more high-quality research and studies with larger participant populations. Conclusion Dysbiosis on the scalp, within the hair follicle and the gut seem to have a role in the pathophysiology of various forms of alopecia. There is evidence that interventions targeting dysbiosis may have potential in the treatment and management of hair loss. Further studies are needed to establish a direct connection and to clarify specific effects of these interventions.

Abstract
Preliminary findings from multiple studies indicate that dietary intake of soy-derived isoflavones exert beneficial effects on the skin including defense against oxidant damage, stimulation of collagen synthesis, and increased hydration. This study aims to investigate how oral supplementation of a soy protein isolate with added isoflavones (SPII) affects components of photoaging such as facial wrinkles and dyspigmentation, and skin biophysical measures such as skin hydration and sebum excretion in postmenopausal women. This 6-month prospective, randomized double-blind controlled study was conducted on 44 postmenopausal women with Fitzpatrick skin types I, II, and III who were randomized to receive either casein protein or SPII. A high-resolution facial photography system was used to measure wrinkle severity and pigmentation at 0, 8, 16, and 24 weeks. Skin biophysical measurements included skin hydration and sebum production. The average wrinkle severity was decreased in the SPII intervention group at week 16 and week 24 by 5.9% and 7.1%, respectively, compared to the baseline. Compared to the casein group, average wrinkle severity was significantly decreased at week 16 (p < 0.05) and week 24 (p < 0.0001). Facial pigment intensity was decreased by -2.5% (p < 0.05) at week 24, whereas there was no significant change in the casein group. Compared to baseline, skin hydration in the SPII group was significantly increased by 39% and 68% on the left and right cheeks (p < 0.05), respectively, at 24 weeks. There were no significant differences in sebum production. Dietary soy protein supplementation with isoflavones may improve skin photoaging, including wrinkles and dyspigmentation, and increase skin hydration in postmenopausal women with Fitzpatrick skin types I, II, and III.

Abstract
Acne vulgaris is a common inflammatory condition that is multi-factorial and impacted by both intrinsic and extrinsic features. Several previous studies have assessed for correlations between factors such as circulating hormones, stress, or the microbiome. However, there have not been any correlations specifically against lesion counts or differentiating correlations between inflammatory and non-inflammatory lesion counts. Here, we correlate several factors against acne lesions. Twenty men and women with mild to moderate acne were recruited, and their hormonal levels and their gut microbiome were collected and correlated against their inflammatory and non-inflammatory lesions of acne. Facial non-inflammatory lesions were weakly correlated to sebum excretion rate and weakly inversely correlated to forehead and cheek hydration. We examined stress through the use of a normalized peak-to-trough ratio (higher numbers indicated less stress), which correlated with skin hydration and inversely correlated with sebum excretion rate. Sebum excretion rate was weakly correlated to testosterone levels, and facial hydration correlated with estradiol levels. Correlations with the gut microbiome showed differential correlations with inflammatory and non-inflammatory lesions, with Clostridium sp AF 23-8 correlating to inflammatory lesion counts, while Actinomyces naeslundii str Howell 279 correlated to non-inflammatory lesions. Overall, measures of stress and circulating hormones correlate to skin biophysical properties and acne lesion counts. Also, different gut bacteria correlate with either inflammatory or non-inflammatory lesion counts. We hope that our findings stimulate further work on the gut-mind-stress-skin axis within acne.

Abstract
Introduction The vermillion lip has unique physical properties and environmental exposures make them prone to dryness and chapping. While lips contribute to facial beauty, perioral aging is highly individual and dependent on ethnicity. Specifically with regard to South Asian population, there is no other literature identified on the biophysical characteristics of the vermillion lip. Methods In this work, characteristics of the vermillion skin in South Asians were examined through various clinical and biophysical characteristics of the lips such as dryness and roughness, fine lip lines, lip texture, hydration, and barrier function. Healthy South Asian females, from age 20-45 were recruited for this study and transepidermal water loss (TEWL), hydration, visual lip tolerance, and visual dryness were measured and graded by the dermatologist-investigator. Results Lip texture and fine lines significantly increased from the 20s to the 40s. Overall lip health significantly decreased with age. TEWL and dryness increased with age while hydration decreased with age, although not significantly so. Discussion This first-of-its kind study on South Asian females establishes that with age there is a decrease in overall lip health and an increase in signs of aging of the lips (fine lines, texture) from the 20s to 40s.

Abstract
Soybean, a legume native to Southeast Asia, serves many nutritional and medical purposes due to its rich source of phytochemicals and its antioxidant activity. Many animal and in vitro studies have demonstrated its potential impact on dermatologic health. The objective of this review is to investigate the clinical response of soy-based oral supplementation or topical application on dermatologic outcomes. A systematic review of studies assessing soy supplementation or application was performed in January 2023. Databases included PubMed, Embase, Cochrane, and Natural Medicines, and studies assessing any formulation that included soybean or associated products were included. Thirty studies met the inclusion criteria and are included in the review; 13 of these studies assessed oral supplementation and 17 assessed topical application. Topical and oral supplementation demonstrated efficacious results for a variety of dermatologic parameters, including chronological or photoaging parameters, skin barrier status, hydration, hyperpigmentation, dermal network composition, erythema, hair and nail parameters, acne lesion counts, and vulvar lichen sclerosis scores. Factors associated with aging, such as wrinkle area and depth, were most frequently assessed among the studies, and both topical and oral studies demonstrated efficacy. Effects are likely mediated by dermal compositional changes, such as increased collagen and/or elastic fiber numbers. Transepidermal water loss measurements, an indicator of skin barrier status, were frequently obtained among the studies, although improvement was more likely achieved with topical application compared to oral supplementation. The results of this review highlight the utility of soy-based products for a variety of dermatologic applications, although future studies are required to determine optimal formulations and application routes for intended outcomes.

Abstract
Psoriasis and atopic dermatitis are chronic inflammatory skin conditions, each affecting about 2-3% of the United States adult population. Phototherapy, such as narrowband ultraviolet-B (NB-UVB) therapy have been employed for the treatment of both psoriasis and atopic dermatitis for decades. More recently, systemic biologics have been approved by the Food and Drug Administration (FDA), representing a great advancement in dermatology. No comprehensive study to date has compared the cost efficacy of phototherapy compared to FDA-approved biologics for the treatment of psoriasis and atopic dermatitis. We pursued a systematic review of the literature for studies assessing efficacy of NB-UVB or biologics with endpoints including the Psoriasis Area and Severity Index (PASI) and the Eczema Area and Severity Index (EASI). Thirty-four studies including 55 treatment regimens and 5,123 patients were included in the analysis. Phototherapy costs were estimated with Medicare fee schedules for phototherapy-related current procedural terminology code (CPT), and biologic costs were estimated with wholesale acquisition cost (WAC). Total costs to achieve PASI 75 or EASI 75 in each study were standardized to a single month, the "adjusted cost," and exploited to a year, the "effective yearly cost," allowing direct cost-efficacy comparison despite different durations of treatment described in studies. The psoriasis analysis found NB-UVB to be the most cost-effective therapy, with an adjusted monthly cost of $1714.00 per PASI 75. Infliximab was the least expensive biologic, with an adjusted monthly cost of $2076.00 to $2502.00 per PASI 75. For atopic dermatitis, no NB-UVB studies utilized EASI 75 as their outcome measure, hindering the ability to directly compare cost effectiveness for the treatment of atopic dermatitis. However, all NB-UVB studies depicted a reduced treatment cost per treatment period compared to studies assessing biologics, although this comparison does not account for efficacy. The results depict NB-UVB to be the most cost effective for the treatment of psoriasis and the least expensive per treatment period for the treatment of atopic dermatitis. However, certain factors need to be taken into account. Biologics may be more effective for more severe disease, do not require multiple weekly clinic visits, and the ease for patient compliance may lead some to favor biologic therapy. This study is necessary to allow physicians, patients, and health systems to make informed decisions regarding cost-efficacy for a variety of treatment options.

Abstract
BACKGROUND Beeswax is a naturally occurring product secreted from worker bees that has varied uses in modern day. In skincare, its function ranges from its role as an occlusive, helping to create a semi-occlusive skin barrier that minimizes transepidermal water loss; as a humectant, locking in hydration; and an emollient to soften and soothe the skin. As a natural substance, its use has been shown to help alleviate symptoms associated with common cutaneous conditions like dermatitis, psoriasis, and overgrowth of normal skin flora. AIMS In this narrative review, we aim to describe current uses of beeswax in skincare that has been published in the literature. MATERIALS AND METHODS A review of beeswax related publications was performed by searching the PubMed database studies. RESULTS A total of five clinical studies were included with three studies on animals and two studies in humans. DISCUSSION Several studies show the benefits of topical beeswax in supporting the skin barrier. CONCLUSION Beeswax can be a low-cost, natural ingredient for use in products. Further studies with topical beeswax are warranted.

Abstract
Sneddon-Wilkinson disease, also known as subcorneal pustular dermatosis (SPD), is a rare disease characterized by vesicles or pustules that may rapidly expand and coalesce. Idiopathic in nature, SPD's clinical presentation of "half-half" blisters, with half of each blister containing pus and half containing clear fluid, is characteristic of this disease. We describe a previously healthy 21-year-old man who developed acute pustular vesicular eruptions consistent with SPD eight days following the Moderna COVID-19 vaccination.

Abstract
Acne vulgaris is a common inflammatory condition that can be associated with profound psychosocial impacts. Conventional treatment includes topical retinoids, benzoyl peroxide, and antimicrobials, and some may cause irritation and skin dryness. In this 8-week open-label study, we examined the effects of a botanical skin care regimen (Codex Labs Shaant Balancing regimen) on mild to moderate facial and truncal acne. Twenty-four male and female subjects between the ages of 12 and 45 years were assessed for eligibility, 20 were enrolled, and 15 completed all study visits. Facial and truncal acne lesion counts, skin hydration, sebum excretion rate, and mood were assessed at baseline, week 4, and week 8. Total facial lesion counts (inflammatory and non-inflammatory lesions) decreased by 20.5% at week 4 (p = 0.06) and by 25.2% at week 8 (p < 0.05). Inflammatory lesion counts on the trunk were found to decrease at week 8 relative to baseline by 48% (p < 0.05). Forehead sebum excretion rate decreased by 40% at week 4 (p = 0.07) and 22% at week 8 (p = 0.08), and cheek skin hydration increased by 27.6% at week 4 (p = 0.14) and 65% at week 8 (p = 0.10). Participants also experienced significant improvement in components of a positive effect, such as feeling "strong" and "inspired", and a decrease in negative effects, such as feeling "irritable." Overall, the botanical skin care regimen was found to be well-tolerated. Our study suggests that a botanical skin care regimen may reduce facial and truncal acne lesion counts, increase skin hydration, reduce sebum production, and augment positive effects and moods in those with mild to moderate facial and truncal acne.

Abstract
Alopecia is associated with significant psychological burden. There is limited evidence on the use of psychological interventions in conditions of hair loss. This manuscript systematically reviews the current state of literature on psychological treatments for quality of life, mental health, and hair growth in various forms of alopecia. PubMed and Embase were searched with predefined inclusion and exclusion criteria. Reference lists were also examined for relevant studies. Nine articles met our criteria and are included in this review. Eight of the articles related to alopecia areata and one related to scarring alopecia. Mindfulness-based stress reduction (MBSR) was found to improve quality of life-related subjective symptoms, relationship impacts, anxiety, phobia, distress, and psychological symptom intensity. Alopecia-specific collocated behavioral health (CLBH) treatment showed a trend for psychosocial improvement in areas such as appearance shame, activity avoidance, negative emotions, and coping. Hypnotherapy was found to improve anxiety and depression, quality of life measures, and alexithymia. There was also some evidence for significant hair growth with hypnosis, but the data are mixed. Psychotherapy combined with immunotherapy led to more hair growth, and supported self-confidence. Finally, coping strategies modulated the subjective burden of alopecia, and were associated with disease improvement. Further research will be necessary to better establish the efficacy and optimal administration of these interventions in alopecia.

Abstract
Probiotic supplementation has been shown to modulate the gut-skin axis. The goal of this study was to investigate whether oral spore-based probiotic ingestion modulates the gut microbiome, plasma short-chain fatty acids (SCFAs), and skin biophysical properties. This was a single-blinded, 8-week study (NCT03605108) in which 25 participants, 7 with noncystic acne, were assigned to take placebo capsules for the first 4 weeks, followed by 4 weeks of probiotic supplementation. Blood and stool collection, facial photography, sebum production, transepidermal water loss (TEWL), skin hydration measurements, and acne assessments were performed at baseline, 4, and 8 weeks. Probiotic supplementation resulted in a decreasing trend for the facial sebum excretion rate and increased TEWL overall. Subanalysis of the participants with acne showed improvement in total, noninflammatory, and inflammatory lesion counts, along with improvements in markers of gut permeability. The gut microbiome of the nonacne population had an increase in the relative abundance of Akkermansia, while the subpopulation of those with acne had an increase in the relative abundance of Lachnospiraceae and Ruminococcus gnavus. Probiotic supplementation augmented the circulating acetate/propionate ratio. There is preliminary evidence for the use of spore-based probiotic supplementation to shift the gut microbiome and augment short-chain fatty acids in those with and without acne. Further spore-based supplementation studies in those with noncystic acne are warranted.

Abstract
OBJECTIVE This study aims to evaluate the in vitro and clinical effects of topical acetylhexapeptide-8 (AH8) on the appearance of oily skin. METHODS In vitro SEB-1 human sebocyte cell lines were exposed to different concentrations of AH8 , then the lipid content of the sebocytes was measured. For the randomized, controlled, split-face clinical study, participants received AH8 10% lotion formulated in Cetaphil Moisturizing Facial Lotion on one side of their face and the control vehicle lotion on the other side of their face. Facial oiliness was assessed by a trained physician using a 3-point grading system, high-resolution digital photographs, and a sebumeter (SM815). Participants also filled out self-assessments of their skin oiliness. RESULTS The in vitro experiments showed that sebocyte lipid content significantly decreased after AH8 treatment (p < 0.05 at 0.00005% AH8 , p=0.09 at 0.0005% AH8 , p < 0.05 at 0.005% AH8,and p < 0.001 at 0.025% AH8). In the clinical study, participants trended towards a 10% reduction (p=0.16) in sebum production after AH8 treatment in comparison to the vehicle treatment. CONCLUSION AH8 inhibits the accumulation of lipids in sebocytes in vitro without altering cell proliferation or SREBP-1 expression. Topical AH8 trended toward decreased sebum production in human participants. The use of AH8 may serve as a promising agent to reduce sebocyte lipid production and the appearance of oily skin.

Abstract
The potential role of plant-based foods in the promotion of skin health is an emerging area of nutrition research. Plant-based foods are rich in bioactive compounds, including vitamin C, vitamin E, beta carotene, polyphenols, and phenolic acids, which can contribute to oxidant defense, lower inflammation, and promote structural support of the skin. Epidemiological studies have associated higher intakes of select fruits and vegetables with positive skin health. Beneficial effects of certain fruits, vegetables, nuts, legumes, and polyphenolic-rich beverages on the skin have been reported, with each of these providing a unique phytochemical composition. Although most studies use extracts, this review will focus on data from whole foods and minimally processed products. Collectively, the evidence to date suggests a promising future for plant-based dietary interventions that promote skin barrier health and function. However, additional research is required to address issues such as the optimal quality and duration of intake as well as potential mechanisms. Studies in the above areas will help formulate specific targeted dietary recommendations.

Undermining is thought to improve wound outcomes; however, randomized controlled data regarding its efficacy are lacking in humans. The objective of this randomized clinical trial was to determine whether undermining low to moderate tension wounds improves scar cosmesis compared to wound closure without undermining. Fifty-four patients, 18 years or older, undergoing primary linear closure of a cutaneous defect with predicted postoperative closure length of ≥ 3 cm on any anatomic site were screened. Four patients were excluded, 50 patients were enrolled, and 48 patients were seen in follow-up. Wounds were divided in half and one side was randomized to receive either no undermining or 2 cm of undermining. The other side received the unselected intervention. Three months, patients and 2 masked observers evaluated each scar using the Patient and Observer Scar Assessment Scale (POSAS). A total of 50 patients [mean (SD) age, 67.6 (11.5) years; 31 (64.6%) male; 48 (100%) white] were enrolled in the study. The mean (SD) sum of the POSAS observer component scores was 12.0 (6.05) for the undermined side and 11.1 (4.68) for the non-undermined side (P = .60). No statistically significant difference was found in the mean (SD) sum of the patient component for the POSAS score between the undermined side [15.9 (9.07)] and the non-undermined side [13.33 (6.20)] at 3 months. For wounds under low to moderate perceived tension, no statistically significant differences in scar outcome or total complications were noted between undermined wound halves and non-undermined halves.

Abstract
PURPOSE Lower socioeconomic status is associated with decreased sun protection practices. This survey study investigated practices and beliefs surrounding sun protection based on health insurance. METHODS 401 surveys were administered May to June 2019 at two dermatology clinics in Sacramento, California. 384 surveys by private insurance, Medi-Cal (California's Medicaid), and Medicare coverage were analyzed. RESULTS Patients with Medi-Cal are twice as likely to rarely or never use sunscreen (OR=2.37; 95% CI 1.45-3.87; P<0.001) compared to those with private insurance. Patients with Medi-Cal or Medicare are less likely to use sunscreen (P<0.001), protective clothing (P=0.025), and sun avoidance (P=0.028). Medi-Cal patients more often used tanning beds (OR=4.90; 95% CI 1.30-18.50; P=0.019). Over half of patients with Medi-Cal agreed it is worth getting burned for a tan (54.6%, OR=2.54; 95% CI 1.41-4.62; P=0.0021). There were no significant differences in opinion that sunscreen is a hassle to apply or expensive. Groups did not differ significantly in ethnicities or skin type. CONCLUSION Those with Medi-Cal are less likely to use all forms of sun protection and more likely to value tanning. Negative opinions of sunscreen and perceived knowledge and concern for skin cancer were similar, pointing to additional factors influencing these disparities.

Abstract
We present a 76-year old man who developed papulopustular rosacea after receiving nivolumab treatment for his esophageal carcinoma, metastatic to the lungs. Nivolumab is an emerging cancer therapy whose immune-related adverse events are still not fully recognized and likely underreported. The treatment has been reported to cause a myriad of cutaneous immune-related adverse events. However, nivolumab-induced-papulopustular rosacea has been scarcely reported. Thus, this case presents a clinically important finding that physicians should be aware of when seeing patients on nivolumab therapy.

Abstract
We present a patient with anti-MDA5 negative, anti-Ku positive clinically amyopathic dermatomyositis (CADM). A 61-year-old woman presented with a chief complaint of a 20-year history of a pruritic rash that was active on her face, chest, hands, legs, and back. A mildly scaly, erythematous, photo-distributed eruption along with slightly violaceous, scaly papules accentuated on the wrist, metacarpophalangeal joints, proximal interphalangeal and distal interphalangeal joints. Antibody profile was significant for positive ANA and anti-dsDNA, elevated anti-TIF-1gamma (RDL)/p155, and weakly positive anti Ku. Biopsy was consistent with dermatomyositis. Melanoma differentiation-associated gene 5 antibody (anti-MDA-5) has been identified as the most commonly associated autoantibody found in CADM and is associated with poor prognosis and a biomarker for the diagnosis of rapidly progressive interstitial lung disease. To our knowledge, our patient is the first case of negative anti-MDA-5 and anti-Ku positive CADM.

Abstract
Background: Vitiligo is an autoimmune skin condition that affects people globally anywhere, from <0.1% to more than 8% of individuals. The disease destroys skin melanocytes, resulting in a patchy depigmentation of the skin. About 50% of all patients develop the disease before their 20s. Methods: We systematically searched the literature and reviewed the evidence for the use of nutritional supplements and diet in the management of vitiligo. Embase and Medline were searched for diet, herbal, and nutrition-based clinical studies. Additional filters were applied that looked for controlled trial or randomized controlled trial and article or article in press or letter and English and clinical study. We selected clinical studies in humans that showed how diet or natural supplements can improve the symptoms of vitiligo in all of our searches. Results: There were 62 manuscripts that resulted from the PubMed search and 259 from the Embase search. A final of 26 studies were reviewed, and other supplemental case and case-control studies were used to introduce diet components that may influence either exacerbation or amelioration of vitiligo. Possible mechanisms of action are introduced for natural and supplemental interventions. Conclusion: Some of the supplements reviewed include Gingko biloba, oral Polypodium leucotomos, alpha lipoic acid, vitamins B12, D, and E, folic acid, phenylalanine, canthaxanthin, Nigella sativa oil, and other combined herbal bio-actives. Overall, the growing evidence is promising, but more studies are needed in this area to further explore the impact that supplements and diet can have on vitiligo management. The most promising therapies included oral phenylalanine as adjuvant therapy with UVA therapy, oral G. biloba as monotherapy, both of which can be used with other traditional therapies, and oral P. leucotomos with phototherapy or photochemotherapy.

Abstract
Background: Broad-spectrum antibiotics are the first-line treatment for small intestinal bacterial overgrowth (SIBO). However, many antibiotics have a considerable side-effect profile and SIBO commonly reoccurs after successful eradication with antibiotics. Alternative therapies such as probiotics, therapeutic diets, and herbal medicines have been used to individualize SIBO management, particularly in recalcitrant cases. Objectives: The objective of this review is to evaluate the role of alternative therapies in SIBO treatment. Data Sources: EMBASE, MEDLINE, and the Cochrane Central Register were systematically searched for clinical studies evaluating alternative therapies in the management of SIBO. Study Eligibility Criteria: Human studies in which an alternative intervention was used to treat SIBO were included. Alternative interventions were defined as an intervention that included a probiotic supplement, herbal preparation, or a dietary change. Randomized controlled trials (RCTs), nonrandomized clinical trials with or without a control, and crossover studies were included. Study Appraisal: The following information was extracted from the selected studies: study type, study participants, SIBO subtype, intervention, comparison, outcome measures, relevant results, relevant side effects, and Jadad score. Results: Eight studies met inclusion criteria. The studies evaluated probiotics (n = 5), therapeutic diet (n = 1), and herbal medicines (n = 2). Among these studies, there were four RCTs, two open-label single-arm studies, one randomized, double-blind crossover study, and one two-arm open-label study with crossover. Main results are summarized. Limitations: There may be studies not captured by the defined search criteria. Additionally, studies used different methodologies in both breath testing and measurement of clinical symptoms, making it difficult to draw conclusions on SIBO eradication and symptom improvement across studies. Conclusions and Implications: Our findings suggest preliminary evidence for a role of alternative therapies in the treatment of SIBO. However, robust clinical trials are generally lacking. Existing studies tend to be small and lack standardized formulations of treatment. Breath testing protocols and clinical symptom measurement greatly varied between studies. Large-scale, randomized, placebo-controlled trials are needed to further evaluate the best way to utilize alternative therapies in the treatment of SIBO.

Abstract
Objectives: Triphala (which contains Emblica officinalis, Terminalia bellerica, and Terminalia chebula) and manjistha (Rubia cordifolia), have received increased clinical attention. The aim of the study was to evaluate the effects of triphala, manjistha, or placebo dietary supplementation on gut microbiota as such studies in humans are lacking. Design: This was a 4-week randomized, double-blind, placebo-controlled pilot trial. Setting: This trial was conducted at the University of California Davis, Department of Dermatology. Subjects: A total of 31 healthy human subjects were randomized to 3 groups. Interventions: The 3 groups were instructed to take 2,000 mg of either triphala, manjistha or placebo daily for 4 weeks. Outcome Measures: The impact of treatment on gut microbiota composition was evaluated following a 4-week dietary intervention by profiling fecal communities with 16S rRNA profiling in triphala (n = 9), manjistha (n = 9), or placebo (n = 11) treated subjects that completed the intervention. Results: An average of 336 phylotypes were detected in each sample (range: 161 to 648). The analysis of gut microbiota in placebo control and herb-supplemented participants indicated that responses were highly personalized, and no taxa were uniformly altered by the medicinal herb supplementation protocol. Subjects in both treatment groups displayed a trend toward decreased Firmicutes to Bacteroidetes ratio and increased relative abundance of Akkermansia muciniphila. Both medicinal herb treatments reduced the relative abundance of Rikenellaceae, primarily reflecting changes in Alistipes spp. Conclusions: Dietary supplementation with medicinal herbs altered fecal microbial communities. Despite the lack of a clear response signature, a group of bacterial taxa were identified that were more commonly altered in herb-supplemented participants compared to placebo controls.

Abstract
OBJECTIVE Acetyl zingerone (AZ), a derivative of the phytochemical zingerone from Zingiber officinale (ginger), is a novel compound that is purported to have antiaging properties. The objective of this clinical study was to assess the role of acetyl zingerone in its ability to improve the appearance of facial skin wrinkles, redness, pigmentation, and photoaging was assessed. METHODS Thirty-one healthy participants (age 44 ± 7 years) were randomized in blinded fashion to apply either 1% AZ or placebo, consisting of the vehicle base cream, to the full face twice daily for 8 weeks with a total of 3 visits. Signs of photoaging, including wrinkles, dyspigmentation, and redness were assessed with facial image analysis photography and software. RESULTS There was a significant decrease in average wrinkle severity (P = .019; Mean=-25.7% change), total wrinkle volume (P = .003; Mean=-30.1% change), pigment intensity (P = .021; Mean=-25.6% change), and redness intensity (P = .035; Mean=-20.7% change) in the AZ group by 8 weeks compared with the placebo. No significant itching, burning, or stinging was noted by study participants. There was also no significant difference between both groups in the clinical assessment of scaling, erythema, hypopigmentation, or hyperpigmentation. CONCLUSIONS AND RELEVANCE Topical AZ improves photodamage and decreases the appearance of wrinkles, dyspigmentation, and redness intensity when compared to placebo (vehicle) formulation. Acetyl zingerone is well tolerated with daily use.

Abstract
Skin is the largest peripheral endocrine organ and functions as a hormone target and endocrine gland. A cutaneous hypothalamus-pituitary-adrenal (HPA)-like axis enables the skin to respond to stress and regulates its steroidogenic activity. The pilosebaceous unit is a site for production and metabolism of a number of steroid hormones, including stress and sex hormones. This is an overview of the important role that the cutaneous HPA-like-axis plays in the pathogenesis and treatment of inflammatory pilosebaceous disorders, including acne, rosacea, seborrheic dermatitis, and hidradenitis suppurativa.

Abstract
Importance Surgeons have varying opinions on the ideal cutaneous suture spacing for optimal cosmetic outcomes. To date, no studies concerning the effect of suture spacing on cosmetic outcomes exist in the literature. Objective To compare outcomes and wound cosmesis achieved with running cutaneous sutures spaced 2 vs 5 mm apart. Design, Setting, and Participants This randomized clinical trial was conducted at the University of California, Davis dermatology clinic from November 28, 2017, to June 15, 2018. Fifty-six patients 18 years or older with surgical fusiform wounds (from Mohs procedure or surgical excision) on the head or neck with assumed closure lengths of at least 3 cm were screened. Six patients were excluded, 50 patients were enrolled, and 48 patients were followed up. Interventions Fifty surgical fusiform wounds were randomized to running cuticular closure with 2-mm spacing on half and 5-mm spacing on half. Main Outcomes and Measures At 3 months, patients and 2 masked observers evaluated each scar using the Patient and Observer Scar Assessment Scale (POSAS). Results A total of 50 patients (mean [SD] age, 71.1 [11.4] years; 43 [86%] male; 50 [100%] white) were enrolled in the study. The mean (SD) sum of the POSAS observer component scores was 10.7 (4.3) for the 2-mm interval side and 10.8 (3.5) for the 5-mm side at 3 months (P = .77). No statistically significant difference was found in the mean (SD) sum of the patient component for the POSAS score between the 2-mm interval side (10.2 [4.7]) and the 5-mm interval side (11.5 [6.4]) at 3 months (P = .24). No statistically significant difference was observed in mean (SD) scar width between the 2-mm side (0.9 [0.6] mm) and the 5-mm side (0.8 [0.4] mm; P = .15). Conclusions and Relevance No statistically significant difference in wound cosmesis or total complications were noted between running cuticular sutures spaced 2 vs 5 mm apart. Both suturing techniques resulted in similar cosmetic outcomes and complication rates. Surgeons may want to consider whether the extra time involved in placing very closely spaced cuticular sutures is worthwhile. Trial Registration ClinicalTrials.gov identifier: NCT03330041.

Abstract
BACKGROUND Zinc has been used in patients with acne vulgaris for its anti-inflammatory effects; however, it is unclear if zinc supplementation is also beneficial in other inflammatory skin conditions. OBJECTIVE The objective of this article was to determine the effect of zinc supplementation on inflammatory dermatologic conditions. DATA SOURCES We searched the Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, and Ovid with no time limit up to 29 May, 2019. Trials examining supplementation with zinc in the treatment of inflammatory dermatological conditions (acne vulgaris, atopic dermatitis, diaper dermatitis, hidradenitis suppurativa, psoriasis, and rosacea) in children and adults were selected. RESULTS Of 229 articles, 22 met inclusion criteria. Supplementation with zinc was found to be beneficial in ten of 14 studies evaluating its effects on acne vulgaris, one of two studies on atopic dermatitis, one of one study on diaper dermatitis, and three of three studies evaluating its effects on hidradenitis suppurativa. However, the one article found on psoriasis and the one article found on rosacea showed no significant benefit of zinc treatment on disease outcome. CONCLUSIONS AND IMPLICATIONS Some preliminary evidence supports the use of zinc in the treatment of acne vulgaris and hidradenitis suppurativa; however, more research is needed with similar methodologies and larger sample sizes in these diseases. Further, zinc may be of some benefit in the treatment plan for atopic dermatitis and diaper dermatitis; however, additional studies should be conducted to further evaluate these potentially positive associations. To date, no evidence is available to suggest that zinc may be of benefit in rosacea and psoriasis; however, limited data are available evaluating the use of zinc in these conditions.

Abstract
Microorganisms inhabit various areas of the body, including the gut and skin, and are important in maintaining homeostasis. Changes to the normal microflora due to genetic or environmental factors can contribute to the development of various disease states. In this review, we will discuss the relationship between the gut and skin microbiome and various dermatological diseases including acne, psoriasis, rosacea, and atopic dermatitis. In addition, we will discuss the impact of treatment on the microbiome and the role of probiotics.

Abstract
OBJECTIVE Almonds are a rich source of fatty acids and antioxidants, and their supplementation is known to significantly modulate serum lipids. The effects of almond on the skin's lipid barrier and the appearance of wrinkles have not yet been elucidated. The aim of this study was to investigate the effects of almond consumption on facial sebum production and wrinkles. METHODS This was a prospective, investigator-blinded, randomized controlled trial in which subjects consumed 20% of their daily energy consumption in either almonds or a calorie-matched snack for 16 weeks. This study was completed at the UC Davis Dermatology clinic. Participants were a volunteer sample of generally healthy postmenopausal females with Fitzpatrick skin types 1 and 2. A facial photograph and image analysis system was used to obtain standardized photographs and information on wrinkle width and severity at 0, 8, and 16 weeks. Measurements of transepidermal water loss and sebum production were also completed at 0, 8, and 16 weeks. RESULTS Fifty healthy postmenopausal females were recruited, 31 participants were enrolled, and 28 completed the study. Under photographic analysis, the almond group had significantly decreased wrinkle severity and width compared with the control group at 16 weeks (p < .02). Changes in skin barrier function were nonsignificant, measured by the transepidermal water loss (p = .65) between the almond and control groups relative to baseline after 16 weeks. No adverse effects were reported. CONCLUSION Our study demonstrates that daily almond consumption may reduce wrinkle severity in postmenopausal females to potentially have natural antiaging benefits.

Abstract
Necrobiosis lipoidica is a chronic granulomatous disease of unknown etiopathogenesis, which is often difficult to treat. While data from randomized controlled trials for the treatment of necrobiosis lipoidica is lacking, several treatments of varying efficacy for necrobiosis lipoidica have been reported in the scientific literature. We present a case of a 29-year-old female with uncontrolled diabetes and treatment-resistant necrobiosis lipoidica which was responsive to ustekinumab.

Abstract
The role of the microbiome in healthy and disease states of the human body is progressively being found to extend beyond the gastrointestinal tract and into other organ systems such as the skin. Researching the microbiome thus has become paramount to understanding additional physiological and pathophysiological mechanisms that may be at play between microbes and their hosts. Cell cultures have traditionally been used to study the microbiome, but in our current day and age, advanced metagenomic techniques - such as 16S rRNA amplicon sequencing and whole metagenomic shotgun sequencing - are better able to classify the microorganisms making up the microbiome. Utilizing metagenomics alone, however, does not allow for the study of the more complex effects of the microbiome, such as changes in gene expression and metabolic byproducts. Thus, incorporation of other modalities such as metatranscriptomics, metaproteomics, and metabolomics are needed to further elucidate the extensive intricacies of the skin microbiome.

Abstract
Ultraviolet (UV) radiation is associated with negative health effects, including sun damage and skin cancer. The purpose of this study is to compare the protective effects of the shade provided by a sun umbrella versus that provided by a tree. Sun sensors that register the level and dose of UV radiation were placed in the shade and in direct sunlight. Measurements were recorded every half hour between the hours of 12:30 p.m. and 3:00 p.m. in Sacramento, California. The results suggest that the level of UV radiation in the shade is not zero. The sensors located in tree shade indicated that over 5% of UV radiation was detected in the shade. The sensors located in sun-umbrella shade showed that greater than 17% of UV radiation reached the shade. The sun sensors used in our study collected UV radiation data relevant to UV index; however, they did not differentiate between UVA, UVB, visible, and infrared light. The amount of UV radiation detected in the shade is not zero, thus regular sunscreen use and other sun protective practices should be followed to reduce the risk of sun damage and skin cancer.

Abstract
BACKGROUND Both topical and oral probiotics are becoming widely used. There is increasing interest in the cosmetic potential in topical probiotics. Nitrosomonas eutropha is an ammonia-oxidizing bacteria. AIM The purpose of this study was to assess whether there is any improvement in facial wrinkles with the use of Nitrosomonas eutropha, a topical probiotic. METHODS In this prospective study, high-resolution photographs were obtained in twenty-nine participants at baseline and after using topical Nitrosomonas eutropha for seven days. RESULTS There was a significant difference in wrinkle depth and severity in the high concentration probiotic group. There was also a statistically significant improvement in pigmentation of the forehead and glabella in the higher concentration group. CONCLUSIONS Nitrosomonas eutropha may have aesthetic benefits in terms of reducing the appearance of wrinkles. Larger studies with longer treatment and follow-up periods are required.

Abstract
Actinic keratosis (AK) is an early in situ squamous cell carcinoma that results from UV light exposure and has the potential to evolve into invasive tumor. Therefore, it is crucial that AKs are monitored and treated appropriately. Photodynamic therapy (PDT) is a treatment option that is minimally invasive and leaves patients with cosmetically superior results. However, disadvantages of PDT include pain and lengthy clinic visits. Accordingly, there has been much interest in the use of daylight photodynamic therapy (daylight-PDT) as a more convenient and less painful alternative to conventional photodynamic therapy (c-PDT). Current evidence shows that daylight-PDT is noninferior to c-PDT in the short and long term. Patients reported decreased pain with daylight-PDT and were more satisfied with the procedure (P<0.001). Current evidence suggests that 2 hrs of daylight exposure was sufficient for treatment, and its efficacy does not appear to be limited by weather conditions. Given the decreased intensity of treatment, daylight-PDT is better for mild disease, as it is less effective in moderate-to-thick AKs. Though further studies are still needed to refine the technique, daylight-PDT is a potential alternative to c-PDT for thin-to-moderate AKs and should be offered to patients with lower pain tolerance or busy schedules.
