A Holistic Approach to Antiaging as an Adjunct to Antiaging Procedures: A Review of the Literature

A nanohybrid synthesized by polymeric assembling Au(I)-peptide precursor for anti-wrinkle function

A major sign of aging is wrinkles (dynamic lines and static lines) on the surface of the skin. In spite of Botulinum toxin's favorable therapeutic effect today, there have been several reports of its toxicity and side effects. Therefore, the development of an effective and safe wrinkle-fighting compound is imperative. An antioxidant-wrinkle effect was demonstrated by the peptide that we developed and synthesized, termed Skin Peptide. Aiming at the intrinsic defects of the peptide such as hydrolysis and poor membrane penetration, we developed a general approach to transform the Skin Peptide targeting intracellular protein-protein interaction into a bioavailable peptide-gold spherical nano-hybrid, Skin Pcluster. As expected, the results revealed that Skin Pcluster reduced the content of acetylcholine released by neurons in vitro, and then inhibit neuromuscular signal transmission. Additionally, human experiments demonstrated a significant de-wrinkle effect. Moreover, Skin Pcluster is characterized by a reliable safety profile. Consequently, anti-wrinkle peptides and Skin Pcluster nanohybrids demonstrated innovative anti-wrinkle treatments and have significant potential applications.

Reproduction, skin aging, and sleep in middle-aged women

There is a growing trend for women to delay having children, with a significant number of women postponing motherhood until the third or fourth decade of life. At the same time, these middle-aged women may be more concerned about skin aging and use dermatologic procedures to delay or repair the effects of aging, environmental factors, and oxidative stress on the skin. It has been suggested that the use of skin cosmetics and procedures may play a role in the reproductive system, although their possible effects have not yet been clearly elucidated. Another crucial factor that needs to be raised in this context is poor sleep, which seems to have an important relationship with both reduced fertility and accelerated skin aging, especially when it is associated with greater oxidative stress and hormonal imbalance. This review discusses the important triad of sleep, dermatology, and reproduction, a subject that has received relatively little attention; and, given its potentially wide-ranging implications, one that deserves more frequent and detailed consideration in future studies. Understanding this complex web of interactions could help to provide outcomes that include healthier skin, safety, improved self-esteem, and successful fertility treatments, all of which can directly affect quality of life.

Facial Rejuvenation in Indonesian Skin With a Picosecond 755-nm Laser

Introduction: The aging process in the skin naturally happens over time, affected by several factors, of which ultraviolet irradiation is a major factor, and this leads to the appearance of wrinkles, pigmentations, and textural irregularities. Lasers for facial rejuvenation are very popular in Asian patients, but melanin rick skin types like Asians are more susceptible to pigmentary alterations. Most Indonesians have brown skin, and just a few have light skin. The purpose of this study was to know the efficacy and safety of the picosecond 755 nm laser in facial rejuvenation in Indonesian skin. Methods: This is an analysis of 20 healthy patients with Fitzpatrick skin type III-V with facial photoaging from 36 to 55 years. Examinations were evaluated before therapy and 4 weeks after the second therapy. The front and side of both cheeks were photographed and analyzed by using VISIA. Clinical improvement was categorized as excellent-mild. The patients were also asked and examined about the presence of adverse events. Results: The patients were predominantly female with an average age of 44 years. Sixty percent of the patients had a good improvement and 40% of the patients had a moderate improvement. The VISIA analysis showed a significant improvement in wrinkles, pigments, and textures (P < 0.001). Only mild anticipated adverse events were observed, and there was no post-inflammatory hyperpigmentation or hypopigmentation. Conclusion: the picosecond 755 nm laser is effective and safe for facial rejuvenation in the skin of Indonesian patients without significant adverse events.

Grapevine Wastes: A Rich Source of Antioxidants and Other Biologically Active Compounds

Wine production is one of the most critical agro-industrial sectors worldwide, generating large amounts of waste with negative environmental impacts, but also with high economic value and several potential applications. From wine shoots to grape pomace or seeds, all of the wastes are rich sources of bioactive compounds with beneficial effects for human health, with these compounds being raw materials for other industries such as the pharmaceutical, cosmetic or food industries. Furthermore, these compounds present health benefits such as being antioxidants, supporting the immune system, anti-tumoral, or preventing cardiovascular and neural diseases. The present work aims to be a critical discussion of the extraction methods used for bioactive compounds from grapevine waste and their beneficial effects on human health.

Teachings from COVID-19 and aging-An oxidative process

As of June 2020, the COVID‐19 pandemic has totaled over 9 000 000 cases and 470 000 deaths globally (ref. 1). Emerging data from COVID‐19 patients have suggested a clear role for oxidative stress in the pathogenesis of SARS‐CoV‐2, the pathogenic agent of COVID‐19. Several comorbidities, including hypertension, diabetes, obesity, and aging, have been associated with an increase in baseline oxidative stress, likely explaining why such individuals at risk for poor outcomes with SARS‐CoV‐2 infection. Similarly, the concept of oxidative stress remains one of the best supported theories to explain the mechanism behind aging. Oxidative stress through both endogenous and exogenous sources has known deleterious effects in both aging and SARS‐CoV‐2 infection. Herein, we will review the role of oxidative stress as a key player in both aging and COVID‐19 and highlight why some individuals may have better or poorer outcomes because of this. Additionally, we will discuss potential therapeutic pathways for effectively anti‐aging as we take away from our learnings on COVID‐19.

HA Filler Injection and Skin Quality-Literature Minireview and Injection Techniques

Aging of the face produces many changes in the structure and integrity of the skin and other anatomical aspects, the three major signs of which are volume loss, sagginess, and skin quality change. Through surgical or nonsurgical procedures, it is possible to slow or even reverse these mechanisms through artificial means, including thread lifting, radiofrequency, or filler injection. Filler injections are particularly popular in recent years, owing to their convenience, efficacy, and long-lasting results. In this minireview, the author outlines the basic mechanisms behind facial aging, discusses current literature on each aspect of facial aging, and offers injection protocol recommendations based on past literature and clinical experience.

Three-Dimensional Analysis of Age-Related Orbital and Midfacial Bone Remodeling in Asians

BACKGROUND

Facial bony changes vary among races, yet few studies have been conducted in Asians.

OBJECTIVE

To analyze the aging of orbital and midfacial bones in Asians.

METHODS

Based on the two-dimensional data obtained from the computed tomography scanner of imaging department, 3D reconstructions were conducted to take measurements (orbital diagonal diameter, orbital width, orbital area, maxillary angle, midfacial height, pyriform angle, pyriform width, and pyriform area).

RESULTS

In this retrospective study of 261 subjects, a significant decrease in the orbital diagonal diameter, orbital width, and midfacial height was found in men, whereas women displayed a significant increase in the pyriform width and a significant decrease in maxillary angle and midfacial height by three-dimensional analysis.

CONCLUSION

This study verifies the minor female changes in the orbital region and less dramatic male changes in the midfacial region compared with that in Caucasians. Individualized treatment should be performed according to different genders and races. Further exploration of facial bone metabolism may have valuable implications for Asians.

The psychological and aesthetic impact of age-related hair changes in females

BACKGROUND

While dermatologists focus on practices to promote anti-aging, thinning hair that frames a more rejuvenated face can affect age perception and cosmesis.

OBJECTIVES

To characterize the effects of age-related hair changes on age determination and perceived attractiveness.

METHODS

A search was conducted for articles on intrinsic and extrinsic aging as it relates to hair. Key studies on the hair aging process and its effects on self-perception, confidence, and anti-aging were reviewed.

RESULTS

According to several studies, hair density peaks about 27 years of age or earlier and then decreases from the mid-thirties onward. This serves as an opportunity to prevent or treat hair loss in a similar way we treat aging skin. Without optimizing appearance of hair, overall cosmesis to foster self-perception can be curtailed despite multiple efforts to rejuvenate and restore the aging face.

CONCLUSION

The discrepancy between rejuvenated faces and thinner appearing hair that frames the face highlights the importance of a holistic approach to the anti-aging consultation. To more comprehensively address the aesthetic patient, we need to promote awareness of the onset of these hair changes in order to incorporate prevention and therapeutic strategies to preserve hair to complement overall appearance.

Antioxidant and anti-inflammatory capacities of collagen peptides from milkfish (Chanos chanos) scales

Milkfish (Chanos chanos), which is resistant to water quality changes is the fourth largest aquaculture commodity. Abandoned wastes of fish scale and bones aggravate environmental pollution. In this study, the effect of collagen peptides isolated from milkfish scales (MSCP) by pepsin-soluble collagen method on cell viability was investigated. The antioxidant, anti-inflammatory, and DNA-protective activities of MSCP were also evaluated. Results revealed that more than 95% of viable cells were retained in human keratinocytes after addition of 100 mg/mL MSCP. Measurement of DPPH· and ABTS· + radical scavenging activities and cellular reactive oxygen species revealed the high antioxidant activities of MSCP. MSCP demonstrated anti-inflammatory activities by reducing lipoxygenase activity and nitric oxide (NO·) radicals. Moreover, DNA electrophoresis assay indicated that MSCP treatment can directly protect against cyclobutane di-pyrimidine production and DNA single-strand breaks, which are harmful effects of UV radiation and H₂O₂. Given its antioxidant, anti-inflammatory, and DNA-protective activities, MSCP has potential applications in cosmeceuticals and supplementary health food.
