Mechanistic Insights Into the Photosensitizing Properties of the Topical Retinoid Tazarotene

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Light‐activated retinoids: Tazarotene and its active metabolite tazarotenic acid form long‐lived triplet excited states upon UVA irradiation, generating singlet oxygen and promoting photochemical reactions. These processes correlate with reduced fibroblast viability under light exposure, revealing potential phototoxicity and implications for combined ...

Isaridin E Protects Against UVB-Induced Photoaging by Activating Wnt/β-Catenin Signaling Pathway and Alleviating Mitochondrial Dysfunction

Marine Drugs
Mitochondrial dysfunction is a major contributor to skin photoaging. Activation of the Wnt/β-catenin pathway, a key regulator of developmental processes, can improve mitochondrial abnormalities associated with pathology.

Hesperidin from Chenpi Ameliorates Skin Photoaging by Targeting HSPA1L to Stabilize GPX4 and Suppress Ferroptosis

Antioxidants
Photoaging is an extrinsic skin aging process caused by chronic ultraviolet (UV) radiation. A core pathological feature of photoaging is excessive oxidative stress, which can further induce ferroptosis.

UV PROTECTION WITH ZEOLITE TREATED COTTON KNITTED FABRIC - THE INFLUENCE OF YARN LINEAR DENSITY [PDF]

, 2007
UV radiation (UV-R) can be divided into UV-A, UV-B and UV-C radiation. UV-C radiation get absorbed by atmosphere, but diminishing of the ozone layer results with the reaching of UV-B and UV-A rays on the Earths surface.

Photoaging Protective Effects of Quercitrin Isolated from ‘Green Ball’ Apple Peel

Horticulturae
Premature skin aging, also known as photoaging, refers to the changes in the structure and function of the skin caused by chronic sun exposure. The ultraviolet radiation in sunlight is one of the key factors that cause photoaging.

Epicatechin Gallate Ameliorates UVB-Induced Photoaging by Inhibiting p38α-Mediated Autophagy and Oxidative Stress

Antioxidants
Prolonged exposure to ultraviolet (UV) radiation in sunlight is a major extrinsic factor that impairs skin function and accelerates photoaging. In this study, a murine model of ultraviolet B (UVB)-induced photoaging exhibited characteristic symptoms ...
