Characterization of the forehead skin microbiome in the early phase of acne. J Eur Acad Dermatol Venereol 2024; 38 Suppl 7:3-11.

Abstract
BACKGROUND The skin microbiota is known to be imbalanced in acne vulgaris, but the changes occurring during the early stages of acne onset remain poorly described. OBJECTIVES To characterize the skin microbiome of subclinical stages of acne in adults and adolescents. METHODS The composition and diversity of the microbiota from non-lesional skin on the forehead of subjects with mild-to-moderate acne were compared to the ones from non-acne subjects. Analyses of skin swab samples were performed using high-throughput sequencing of the V1-V3 regions of the bacterial 16S ribosomal RNA gene, the tuf gene fragment of Staphylococcus species and the internal transcribed spacer (ITS1) region of the fungal rRNA gene to determine the relative abundance, alpha-diversity and beta-diversity of bacteria and fungi. RESULTS Compared with non-acne subjects, acne subjects had a higher abundance of Cutibacterium (72.4% vs. 57.8%) and lower abundances of Corynebacterium (2.8% vs. 4.8%) and Streptococcus (1.4% vs. 3.2%). Bacterial alpha- and beta-diversity indices also differed significantly between the two groups, reflecting differences in richness, evenness, abundance and phylogenetic distance between bacterial populations. Differences were also observed at the level of Staphylococcus species: S. capitis was predominant in skin samples from non-acne subjects (46.7%), whereas S. epidermidis was the most abundant Staphylococcus species in non-lesional forehead skin areas of acne subjects (44.2%). Conversely, no significant between-group differences were found for fungi, with Malasseziales being the predominant order in both subject groups. CONCLUSION Dysbiosis was observed very early in subclinical acne stages of the forehead skin, with the overall abundance, richness and evenness of the bacterial population being lower in acne than in non-acne skin samples. Dysbiosis was also found at the level of Staphylococcus species. The development of acne lesions could therefore be prevented by using a skin care product that rebalances facial skin microbiota at very early stages.

Abstract
BACKGROUND Acne vulgaris, a common chronic dermatological condition worldwide, is associated with inflammatory response and Cutibacterium acnes. Individuals with acne vulgaris and sensitive skin have limited suitable treatments due to the skin irritation and side effects exhibited by current hydroxy acidic medications. AIMS This study aimed to evaluate the synergistic effects of Guaiacum officinale (GO) and Rhodomyrtus Tomentosa (RT) extracts for treating acne vulgaris on sensitive skin by inhibiting inflammation. METHODS The phytochemical constituents and antioxidant activity of GO and RT extracts were determined in vitro. The anti-inflammatory effects were investigated in peptidoglycan (PGN)-induced HaCaT cells. Further, a 28-day clinical trial was conducted involving 30 subjects with both sensitive skin and acne to evaluate the efficacy and subjects' satisfaction. RESULTS Total phenolics and flavonoids were detected in GO and RT extracts, the IC50 values for DPPH radical scavenging were 6.15 wt% and 0.76 wt%, respectively. The combination of GO and RT extracts at a 1:1 (v/v) ratio significantly decreased the expression of TLR-2 and TLR-4, as well as the secretion of IL-1α, IL-8, and TNF-α in PGN-induced HaCaT cells, by 2.30-7.93 times compared to GO extract alone (p < 0.05). Moreover, the cream containing 5 wt% the combination significantly improved facial acne and redness (p < 0.05). The number of comedones decreased by 50.00% and papules by 30.65% after 28 days of application. No adverse events were reported and 96.67% of the subjects were satisfied with the treatment. CONCLUSION The efficacy of the GO and RT extracts in synergistically suppressing inflammation, improving acne vulgaris, and reducing redness. The study offers an effective and non-irritant treatment for acne vulgaris in individuals with sensitive skin.

Abstract
In this study, ordinary bamboo charcoal was activated at 750 °C with a steam flow rate of 6.25 L/min for 1.5 h. The effects of triglyceride adsorption by activated bamboo charcoal were investigated using an orthogonal design, and the adsorption mechanism was explored through molecular dynamics. Experimental results revealed that the adsorption capacity of activated bamboo charcoal for triglycerides reached 27.0%. The activated bamboo charcoal exhibited a specific surface area of 560.0 m2/g. The average pore diameter of activated bamboo charcoal was 1.6 nm, whereas that of ordinary bamboo charcoal was 7.2 nm. Molecular dynamics simulations revealed an interaction energy of - 145.12 kcal/mol between the molecular layers of activated bamboo charcoal and the triglyceride molecules, as well as an interaction energy of - 132.73 kcal/mol between the molecular layers of ordinary bamboo charcoal and the triglyceride molecules. The quantity of triglyceride molecules adsorbed by activated bamboo charcoal per gram was estimated to be 1.77 × 1021 while ordinary bamboo charcoal could adsorb merely 1.56 × 1019 triglyceride molecules per gram. This stark contrast in adsorption capacity underscores the superior performance of activated bamboo charcoal than its counterpart.

Abstract
Oats (Avena sativa L.) are used as therapeutic plants, particularly in dermatology. Despite numerous studies on their skin moisturization, anti-inflammation, and antioxidation effects, the precise molecular mechanisms of these effects are only partially understood. In this study, the efficacy of oat sprouts in the treatment of allergic contact dermatitis (ACD) was investigated, and their specific phytoconstituents and exact mechanisms of action were identified. In the in vivo ACD model, by stimulating the mitogen-activated protein kinase signaling pathway, oat sprouts increased the expression levels of proteins associated with skin barrier formation, which are produced during the differentiation of keratinocytes. In addition, in a lipopolysaccharide-induced skin irritation model using HaCaT, steroidal saponins (avenacoside B and 26-deglucoavenacoside B) and a flavonoid (isovitexin-2-o-arabinoside) of oat sprouts regulated the genetic expression of the same proteins located on the adjacent locus of human chromosomes known as the epidermal differentiation complex (EDC). Furthermore, oat sprouts showed immunomodulatory functions. These findings suggest the potential for expanding the use of oat sprouts as a treatment option for various diseases characterized by skin barrier disruption.

Abstract
Comedogenic skin care receives little attention compared to the care or treatment of more serious acne manifestations. Traditional therapies may have limited success with potential side effects. Cosmetic care supported by the effect of a biostimulating laser may offer a desirable alternative. The aim of the study was to evaluate the biological effectiveness of combined cosmetic treatment with lasotherapy on comedogenic skin type using noninvasive bioengineering methods. Twelve volunteers with comedogenic skin type underwent a 28-week application of Lasocare Basic 645® cosmetic gel containing Lactoperoxidase and Lactoferrin in combination with laser therapy (Lasocare® method). The effect of treatment on skin condition was monitored using noninvasive diagnostic methods. The parameters were the amount of sebum, the pore count, the ultraviolet-induced red fluorescence assessment of comedonic lesions (percentage of the area and quantification of orange-red spots), hydration, transepidermal water loss, and pH. A statistically significant decrease in sebum production was observed on the skin of the treated volunteers, as well as a decrease in porphyrins, indicating the presence of Cutibacterium acnes populating comedones and causing enlarged pores. The balance of epidermal water in the skin was regulated adjusting the acidity of the skin coat in individual zones, which decreased the presence of Cutibacterium acnes. Cosmetic treatment in combination with the Lasocare® method successfully improved the condition of comedogenic skin. In addition to transient erythema, there were no other adverse effects. The chosen procedure appears to be a suitable and safe alternative to traditional treatment procedures known from dermatological practice.

Abstract
BACKGROUND Chronic cutaneous pain has a substantial negative impact on quality of life (QoL). Dermo-cosmetics can support therapies for treatment of chronic skin diseases, providing symptomatic relief from chronic cutaneous pain and improved QoL. OBJECTIVES To assess the global tolerance and efficacy of a dermo-cosmetic spray containing Rhealba® Oat Plantlet and Uncaria tomentosa extracts in reducing cutaneous pain when used as a monotherapy or in association with drug or dermo-cosmetic treatments in patients with an underlying skin pathology. METHODS Patients aged ≥1 month with a cutaneous pain level ≥3 and an underlying skin pathology were provided with the spray to use up to six times daily for 6-8 weeks. Immediate effect on cutaneous pain and patient satisfaction were assessed after the first application. Global efficacy and tolerance, reduction in symptoms, improvement in QoL, pain reduction and patient overall satisfaction were assessed after 6-8 weeks. RESULTS Immediately after the first application, significant reductions in cutaneous pain were observed across all age groups (P < 0.0001), with 94% of patients reporting a reduction in pain. After 6-8 weeks, global tolerance was rated 'very good' or 'good' for 97% of patients, and the spray was efficacious in 95% of patients. Patient satisfaction with the efficacy of the spray was 95%. QoL scores improved in 86% and 94% of patients aged ≥12 and <12 years, respectively. Findings were similar across underlying pathology and therapy types (monotherapy or in association with another therapy). CONCLUSIONS The spray was well-tolerated and efficacious in providing symptom relief in patients with mild-to-moderate cutaneous pain, irrespective of the underlying pathology or therapy type.

Abstract
Oats and their seeds, stems, and leaves are approved for use as safe food ingredients. Oat seedlings are environmentally friendly and are becoming increasingly popular as they provide several health benefits. We used the UPLC-CAD to quantitatively analyze isolated compounds (1-11) between 15 cultivars of oat seedlings and their harvest time. Maximum average amount of total contents of isolated compounds was observed after the harvest time of 5 days (4711.3 mg/100 g), while the minimum was observed after the harvest time of 7 days (4184.8 mg/100 g). We demonstrated that all isolated compounds (1-11) showed neuraminidase inhibitory effects, with 6 and 7 being the most active with IC50 values of 3.7 and 20.5 µM, respectively. High content of compounds 6 and 7 was observed (2306.6 mg/100 g) in the Dahan cultivar at 9 days, indicating potential good cultivars with a high content of active compounds and neuraminidase inhibition activity.

Abstract
BACKGROUND The frequency of dermatological procedures is steadily increasing, accompanying a growing demand from patients. Chemical peels are a method of resurfacing in the treatment of various skin conditions. However, during the early healing process, patients may impose downtime on themselves. The erythema, pain and poor aesthetic appearance of the skin can lead to unwillingness to participate in social or professional activities. OBJECTIVES The objective of this study was to evaluate the tolerance and efficacy of a repair cream based on Rhealba Oat plantlets extract and active healing compounds after a peeling procedure. METHODS Men and women, aged 18-65 years, with Fitzpatrick phototype I-IV, who had previously received a medium-depth chemical peel on the face (TCA 30%) entered with their consent a clinical study evaluating the new test product based on Rhealba Oat and active healing compounds. At the beginning of the study, the selected patients received a TCA 30% medium-depth peel. Afterwards, they were treated during 29 days with the repair cream and evaluated for the benefits to downtime and pain. RESULTS Significant reductions of pain (P < 0.0114) and erythema (P < 0.0001) were observed in the study. The downtime reduction with the tested cream was 92% - from 9 days after the previous peeling procedure to 0.74 days with application of the tested cream - a difference of 8.39 days. CONCLUSION In consequence, the tested repair cream based on Rhealba Oat plantlets extract and active healing compounds brings clinical benefit to patients who undergo peeling procedures. By reducing pain and downtime, it allows patients to get back to their daily life activities a week earlier than with previous peels.

Abstract
BACKGROUND Fragile skin is a poorly understood skin condition, particularly in the general adult population. There are currently limited epidemiological data on the prevalence of fragile skin in adults. The objectives of this study were to assess the prevalence of perceived fragile skin across different skin types in representative samples of the general adult populations in Mexico and Russia, and to identify skin characteristics associated with perceived fragile skin. METHODS Two identical cross-sectional surveys, using a short online self-administered questionnaire, were conducted on samples of recruited individuals that were representative of the general Mexican and Russian populations. Participants responded to questions about fragile skin, with the main question being "In your opinion, do you have fragile skin (ie, skin less resistant and reacting quickly to external aggressions)?". The survey also covered questions relating to skin appearance, skin symptoms, skin disease, dermatological procedures, and living environment and climate. RESULTS Overall, 1,210 individuals in Mexico (N=606) and Russia (N=604) completed the online survey. Fragile skin was perceived in 50.0% and 45.9% of participants in Mexico and Russia, respectively. The principal skin appearance characteristics reported by individuals with perceived fragile skin were thin, easily wrinkled, and transparent; the main skin symptoms were dryness, redness, and/or itching (≥50% of individuals in Mexico), and dryness, tightness, and/or redness (>60% of individuals in Russia). Individuals with perceived fragile skin had experienced skin disease and/or undergone a dermatological procedure in the past 12 months, and they reported being exposed to stress (>80% of individuals in both surveys). CONCLUSION A substantial proportion of the general adult population of Mexico and Russia perceived that they had fragile skin, regardless of their skin type; fragile skin was perceived more frequently in women. These findings should assist dermatologists to extend their understanding and management of individuals with perceived fragile skin.

Abstract
The use of cosmeceuticals by patients with acne is common; however, their role is unclear and confusing, with many asking, "Do they really help acne?" Cosmeceuticals are intermediate products between prescription medications and cosmetics, available to consumers over the counter. These products are popular and may be used without the direct supervision of a dermatologist, creating a practice gap in educating patients. Herein, a variety of cosmeceuticals are discussed, including retinoids, niacinamide, and glycolic acid. The evidence for and against cosmeceutical use in patients with acne is reviewed.

Abstract
Within their first days of life, newborns' skin undergoes various adaptation processes needed to accommodate the transition from the wet uterine environment to the dry atmosphere. The skin of newborns and infants is considered as a physiological fragile skin, a skin with lower resistance to aggressions. Fragile skin is divided into four categories up to its origin: physiological fragile skin (age, location), pathological fragile skin (acute and chronic), circumstantial fragile skin (due to environmental extrinsic factors or intrinsic factors such as stress) and iatrogenic fragile skin. Extensive research of the past 10 years have proven evidence that at birth albeit showing a nearly perfect appearance, newborn skin is structurally and functionally immature compared to adult skin undergoing a physiological maturation process after birth at least throughout the first year of life. This article is an overview of all known data about fragility of epidermis in 'fragile populations': newborns, children and adolescents. It includes the recent pathological, pathophysiological and clinical data about fragility of epidermis in various dermatological diseases, such as atopic dermatitis, acne, rosacea, contact dermatitis, irritative dermatitis and focus on UV protection.
