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.

한국어 설명

레티놀은 비타민 A의 코스메틱 그레이드 형태로, 외용 안티에이징 성분 중 가장 임상 연구가 많다. 턴오버 증가·콜라겐 지원·잔주름·톤 외관 개선 효과가 수 주에 걸쳐 나타난다. K-뷰티 포뮬러는 보통 0.05~0.3% 저함량으로 시작하며 진정·보습 성분과 함께 조합해 초기 자극을 완화한다.
