Mechanistic Insights Into the Photosensitizing Properties of the Topical Retinoid Tazarotene

open access: yesChemMedChem, 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 ...
