Atrophic and hypertrophic skin photoaging and melanocortin-1 receptor (MC1R): the missing link

, 2021
To the Editor: Photoaging hasrecentlybeenclassified as either atrophic photoaging (AP), characterized by dyspigmentation, erythema, telangiectasia, fine wrinkling, and a tendency to skin cancers, or hypertrophic photoaging (HP), characterized by deep ...

Platelet‐activating factor‐receptor signaling mediates solar‐simulated light‐induced extracellular vesicle release in human keratinocytes

Photochemistry and Photobiology, EarlyView.
Solar‐simulated light (SSL) promotes extracellular vesicle (EV) release from keratinocytes through a UVB‐driven, oxidative stress‐dependent pathway. SSL‐induced reactive oxygen species (ROS) generate oxidized glycerophosphocholines with PAF agonistic activity, which activate the Platelet‐activating factor receptor (PAFR), leading to acid ...

Peptide CyRL-QN15 alleviates UVB-induced skin aging by promoting the repair of barrier

Ecotoxicology and Environmental Safety
Skin photoaging, a process with substantial physical and psychological impacts, is also a recognized risk factor for skin cancer. Despite advancements in dermatological research, effective prevention and reversal of photoaging remain challenging.

Sun exposure and photoprotection: Habits, knowledge, and attitudes among elite beach soccer players

Photochemistry and Photobiology, EarlyView.
Elite beach soccer players experience high ultraviolet radiation exposure and frequent sunburn episodes despite widespread sunscreen use. Deficiencies in sunscreen reapplication, shade‐seeking behaviors, and skin surveillance practices were identified. These findings highlight the need for targeted photoprotection interventions in beach sports athletes.

Dietary monounsaturated fatty acids intake and risk of skin photoaging [PDF]

, 2012
Background: Intake of monounsaturated fatty acids has been reported to reduce oxidative stress, insulin resistance and related inflammatory processes and may thus protect from skin photoaging.

Understanding exosomes in facial esthetics and skin aging

Periodontology 2000, EarlyView.
Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.

Enhancing Transdermal Delivery: The Role of Gecko-Derived Cathelicidin Peptide G3CY-10 in UV-Induced Skin Photoaging

Biomolecules
Ultraviolet (UV) radiation-induced skin photoaging impacts both appearance and skin health, potentially leading to disorders and cancer. Unlike traditional sunscreens, natural antioxidants can target photoaging at its source.

How to Prevent Photoaging? [PDF]

Journal of Investigative Dermatology, 2005
There are several theories on photoaging and its etiology. At this time, however, the only defenses commonly believed to prevent photoaging are the use of sunscreens to reduce the amount of ultraviolet (UV) that reaches the skin, the use of retinoids to prevent production of collagenase and stimulate collagen production, and the use of antioxidants to ...
