What it is
Retinol is the cosmetic-grade form of vitamin A, the most-studied class of topical anti-aging ingredients. It increases cell turnover, supports collagen, and reduces the look of fine lines and uneven tone over weeks. K-beauty formulations typically start mild (0.05%–0.3%) and pair retinol with calming, hydrating ingredients to lower the initial irritation curve.
