What it is

Glycerin is the most-used humectant in modern cosmetics — a small molecule that draws water from the deeper skin and the surrounding humidity to the surface. It is inexpensive, well-tolerated, and almost universal in K-beauty toners, essences, and creams. Often present at 3–10% in leave-on formulas.

한국어 설명

글리세린은 현대 화장품에서 가장 많이 쓰이는 보습제다. 작은 분자가 진피와 주변 환경의 수분을 표면으로 끌어와 보습 효과를 만든다. 저렴하고 자극이 낮으며 K-뷰티 토너·에센스·크림에 거의 보편적으로 들어간다. Leave-on 포뮬러에서 보통 3~10% 농도로 사용된다.
