In this review, researchers explored how air pollutants increase oxidative stress and inflammation in human skin, affect vitamin D synthesis, and interact with the skin microbiota, also discussing AhR/Nrf2 as a potential target for treating pollution-related skin conditions.

This study reported that urban pollution accelerates facial wrinkle development and increases pigmentation severity in Chinese women over 30, whereas UV exposure affects these signs from age 20. After 45, pollution becomes a key contributor to skin aging.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

Pollution exposure speeds up hair damage.

This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.

This article discusses the need for long-term studies on pathways for children and adolescents in gender services and reports no new findings; the authors call for data on psychological care.

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

This review examines the skin exposome, including solar exposure, air pollution, hormones, nutrition, and psychological factors, but reports no new clinical results.

This review discusses how acute exposures to environmental and internal stressors can quickly alter skin functions, leading to various dermatological symptoms, and calls for more research on these short-term effects.

This study reviewed 54 articles to examine how continuous exposure to air pollution causes hair damage, hair loss, and scalp conditions due to oxidative stress and inflammation, and highlighted anti-inflammatory substances that could mitigate these effects.

This review discusses the impact of air pollution on skin health and suggests that targeting oxidative stress products like HNE could be a new strategy for treating related skin conditions.

This study found that sunlight exposure causes significant structural and chemical damage to hair, including cuticle loss, cortex damage, and discoloration, with water playing a major role in discoloration of brown hair.

This review explores how air pollutants may contribute to various skin diseases and highlights potential mechanisms, but it presents no new clinical findings.

This review discusses the potential use of spin traps in cosmetic products to limit reactive oxygen species generated by pollution, emphasizing the need for further research due to toxicity and regulatory concerns.

This review highlights that air pollution can worsen inflammatory skin conditions and accelerate skin aging, with oxidative stress and skin barrier disruption being key mechanisms involved, suggesting potential roles for antioxidant and anti-inflammatory treatments.

This review discusses the mechanisms by which sunlight exposure aggravates hair aging and highlights the role of hair pigments in providing photochemical protection, reporting no new results.

This review found that exposure to pollutants like PM, NOx, and PAHs is linked to various skin and hair disorders, indicating a need for cosmetics with natural adsorbents to reduce pollutant effects, achieving 30-55% removal efficiency.

This study created new methods to test how well hair care products clean and protect hair from pollution, finding a wide range of effectiveness among different formulas in removing pollutants and preventing their deposit on hair fibers.

This review discusses the links between particulate matter exposure and skin diseases, highlighting oxidative stress and inflammation as key mechanisms; it reports no new clinical results.

This research review found that climate change exacerbates skin conditions like photoaging, inflammatory dermatoses, and skin cancers by causing oxidative stress and inflammation, suggesting that dermatological practices should incorporate environmental and multicultural considerations to optimize patient outcomes in diverse populations.

This article discusses the major role of motor vehicles in contributing to urban air pollution and its significant health impacts, especially in developing countries, but reports no new findings.

This review synthesizes research on solar radiation's multifaceted effects on skin and recent advancements in sunscreen technology, including formulation, testing methods, and the use of AI, to inform future sun protection product development.

This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

Light skin shows more inflammation from sun exposure than dark skin.

This review discusses the chemical effects of UV radiation on hair, hair photoaging, and photoprotective measures, and calls for more focused research in hair photoprotection as a field.

This review discusses the current understanding of hair photodamage and photodegradation and reports no new findings; it highlights unresolved questions about radiation effects and melanin's role in different hair types.

This study found that photoepilation using intense pulsed light significantly reduced hair growth parameters, and phototrichograms may offer an objective method to evaluate its effectiveness.

This study found that air pollution and dust particles are major contributors to hair fall among young adults living in urban areas.
