exfoliant
Gluconolactone (PHA) · 글루코노락톤
INCI: Gluconolactone
Also known as: PHA · Polyhydroxy Acid · 폴리하이드록시산
What it is
Gluconolactone is a PHA — a larger-molecule exfoliant that operates more on the surface and tends to be gentler than AHA/BHA. It also has humectant character, attracting water as it exfoliates. K-beauty positions PHA as the “sensitive-skin-friendly acid,” often combined with soothing extracts.
한국어 설명
PHA(폴리하이드록시산)인 글루코노락톤은 AHA/BHA보다 분자가 커서 표면 위주로 작용하고 자극이 낮은 편이다. 보습 성질도 있어 각질 정돈과 동시에 수분 유지를 돕는다. K-뷰티에서는 “민감 피부용 산” 포지션으로 진정 추출물과 조합되어 사용된다.
