Abstract
Epidemiological and toxicological studies have confirmed that exposure to atmospheric particulate matter (PM) could affect our cardiovascular and respiratory systems. Recent studies have shown that PM can penetrate the skin and cause skin inflammation, but the evidence is limited and contradictory. As the largest outermost surface of the human body, the skin is constantly exposed to the environment. The aim of this study was to assess the relationship between PM and inflammatory skin diseases. Most epidemiological studies have provided positive evidence for outdoor, indoor, and wildfire PM and inflammatory skin diseases. The effects of PM exposure during pregnancy and inflammatory skin diseases in offspring are heterogeneous. Skin barrier dysfunction, Oxidative stress, and inflammation may play a critical role in the underlying mechanisms. Finally, we summarize some interventions to alleviate PM-induced inflammatory skin diseases, which may contribute to public health welfare. Overall, PM is related to inflammatory skin diseases via skin barrier dysfunction, oxidative stress, and inflammation. Appropriate government interventions are beneficial.

Abstract
The increase in air pollution worldwide represents an environmental risk factor that has global implications for the health of humans worldwide. The skin of billions of people is exposed to a mixture of harmful air pollutants, which can affect its physiology and are responsible for cutaneous damage. Some polycyclic aromatic hydrocarbons are photoreactive and could be activated by ultraviolet radiation (UVR). Therefore, such UVR exposure would enhance their deleterious effects on the skin. Air pollution also affects vitamin D synthesis by reducing UVB radiation, which is essential for the production of vitamin D3, tachysterol, and lumisterol derivatives. Ambient air pollutants, photopollution, blue-light pollution, and cigarette smoke compromise cutaneous structural integrity, can interact with human skin microbiota, and trigger or exacerbate a range of skin diseases through various mechanisms. Generally, air pollution elicits an oxidative stress response on the skin that can activate the inflammatory responses. The aryl hydrocarbon receptor (AhR) can act as a sensor for small molecules such as air pollutants and plays a crucial role in responses to (photo)pollution. On the other hand, targeting AhR/Nrf2 is emerging as a novel treatment option for air pollutants that induce or exacerbate inflammatory skin diseases. Therefore, AhR with downstream regulatory pathways would represent a crucial signaling system regulating the skin phenotype in a Yin and Yang fashion defined by the chemical nature of the activating factor and the cellular and tissue context.

Dermatol Ther 2022; 35:e15903. [PMID: 36200921 PMCID: PMC10078143 DOI: 10.1111/dth.15903] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 08/19/2022] [Accepted: 10/04/2022] [Indexed: 11/29/2022]
Abstract
Skin aging goes beyond a chronological process and also results from extrinsic factors referred to as the exposome. Hyaluronic acid (HA) is an important component of the extracellular matrix, with loss starting at 25 years old. While many studies of HA concern topical use, few literature reviews only address the use of topical HA in dermatology. This review describes the different characteristics of HA-containing cosmeceuticals, with a focus on skin aging and the impact of exposome factors on HA synthesis and degradation. A review was performed using the terms HA, hyaluronan, topical, dermatology, cosmetic, aging treatment, exposome, and cosmeceuticals. Results are also presented from a recent randomized controlled trial (RCT), which investigated the additional benefit of using a HA epidermic filler (HA-filler serum) combined with Botulinum toxin type A (BoNTA) to treat signs of skin aging. Subjects were randomized to two groups: HA-filler serum starting 24 h after the BoNTA injection then twice daily for 24 weeks, or the control group, which received BoNTA. HA is a key ingredient used in cosmeceuticals for its hydration/antiaging properties (hygroscopic, rheological, and viscoelastic). Several clinical studies indicate that HA is both well tolerated and effective, adjuvant to both post-surgical and facial rejuvenation procedures. In the RCT, one of few studies to combine BoNTA and HA with a 6-month follow-up, the HA-filler serum lengthened the duration of BoNTA's effect in reducing wrinkles. Numerous studies support HA-based cosmeceuticals as a noninvasive, effective solution for improving skin hydration and rejuvenation.

Abstract
INTRODUCTION Peptide-C ampoules (PC) contain peptides, 10% of vitamin C, hyaluronic acid, and Vichy volcanic mineralizing water. AIMS To assess the effectiveness and tolerability of PC. PATIENTS AND METHODS An observational study conducted in 9 countries in women ≥30 years old with signs of facial skin aging (grade >0 for forehead and/or crow's feet wrinkles and bothered by skin quality). Investigator assessments and subject questionnaires were performed at initial visit and Day 30 after application of PC twice daily for 28 days. Tolerance was assessed throughout the study. RESULTS Effectiveness and safety were analyzed in 1382 and 1742 subjects, respectively. Most subjects (mean age 48.5 ± 8.6 years) had skin phototype II or III (91.7%) and dry or combination skin (63.9%). PC was used as a standalone care or prior to a planned procedure (70%), or after a procedure (30%). Between baseline and Day 30, 63% and 64% of all subjects (N = 1360) had an improvement in forehead wrinkles and crow's feet wrinkles, respectively. Skin hydration improved in 67.3% of subjects. According to investigator and subject assessments, skin quality, skin radiance, skin aging signs, wrinkles, complexion, and skin pores significantly improved by Day 30. Similar results were observed for subgroup analyses when PC was used as standalone skin care or after a procedure. Tolerance of PC was rated as good to very good by 97.7% of subjects. CONCLUSIONS Peptide-C ampoules is effective in reducing visible signs of skin aging, and well tolerated, when used alone or as an adjunct to anti-aging procedures.

Abstract
OBJECTIVE To assess the in vitro efficacy on antioxidant potential, protection against global oxidative stress, and effect on collagen neosynthesis of minimalist formula (Peptide-C ampoules product) containing 10% natural vitamin C, rice and lupin bio-peptides, hyaluronic acid, and Vichy volcanic mineralizing water (active mix). METHODS In-tube quantitative tests ("in-tube screening") assessed global antioxidant properties, anti-lipid peroxidation, anti-protein glycosylation, and metalloproteinase inhibition (anti-collagenase, anti-elastase, and anti-hyaluronidase activity) properties of the formula. Protection against oxidative stress was evaluated on human keratinocyte monolayer cultures, and collagen neosynthesis was quantified on fibroblast monolayer cultures treated with supernatants from product-treated reconstructed human epidermis. RESULTS Product (5% concentration) showed high antioxidant ability (blocking 99.0% oxidation), protection against oxidative stress damage (51.8% lipid peroxidation and 37.8% protein glycosylation decreases), and inhibition of hyaluronidase (21.9%), elastase (47.1%), and collagenase (61.8%). The protective effect was validated on human keratinocyte monolayer cultures in the presence of active mix (0.025%). Oxidative stress (ROS) was reduced by 99.0%, while global oxidative stress (RMS) induced by pollution, UVA radiation, and a combination of both factors was reduced by 48.94%, 8.7%, and 96.28%, respectively. The product increased collagen neosynthesis (11.21%) by cellular dialogue in fibroblasts incubated with product/mix-treated-RHE supernatants. CONCLUSION The combination of ingredients in the product showed high global antioxidant capacity, as well as a protective effect against oxidative stress induced by UVA, pollution, or both combined factors and an ability to stimulate collagen neosynthesis in in vitro studies, which support the clinical efficacy of this product.

Abstract
The human skin is exposed daily to different environmental factors such as air pollutants and ultraviolet (UV) light. Air pollution is considered a harmful environmental risk to human skin and is known to promote aging and inflammation of this tissue, leading to the onset of skin disorders and to the appearance of wrinkles and pigmentation issues. Besides this, components of air pollution can interact synergistically with ultraviolet light and increase the impact of damage to the skin. However, little is known about the modulation of air pollution on cellular senescence in skin cells and how this can contribute to skin aging. In this review, we are summarizing the current state of knowledge about air pollution components, their involvement in the processes of cellular senescence and skin aging, as well as the current therapeutic and cosmetic interventions proposed to prevent or mitigate the effects of air pollution in the skin.

Abstract
Skin, our first interface to the external environment, is subjected to oxidative stress caused by a variety of factors such as solar ultraviolet, infrared and visible light, environmental pollution, including ozone and particulate matters, and psychological stress. Excessive reactive species, including reactive oxygen species and reactive nitrogen species, exacerbate skin pigmentation and aging, which further lead to skin tone unevenness, pigmentary disorder, skin roughness and wrinkles. Besides these, skin microbiota are also a very important factor ensuring the proper functions of skin. While environmental factors such as UV and pollutants impact skin microbiota compositions, skin dysbiosis results in various skin conditions. In this review, we summarize the generation of oxidative stress from exogenous and endogenous sources. We further introduce current knowledge on the possible roles of oxidative stress in skin pigmentation and aging, specifically with emphasis on oxidative stress and skin pigmentation. Meanwhile, we summarize the science and rationale of using three well-known antioxidants, namely vitamin C, resveratrol and ferulic acid, in the treatment of hyperpigmentation. Finally, we discuss the strategy for preventing oxidative stress-induced skin pigmentation and aging.
