Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
THYMIDINE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
Thymidine is a naturally occurring nucleoside consisting of thymine attached to deoxyribose, and is one of the four canonical nucleosides in DNA. It functions as a skin-conditioning agent in cosmetic formulations, potentially supporting cellular repair mechanisms. It is not listed on any EU Annex restrictions and carries no GHS hazard statements, consistent with its status as a fundamental biological molecule. Topically applied nucleosides may serve as precursors for skin cell repair and have been studied in the context of wound healing and anti-aging.
