by COSRX
Updated September 23, 2026
Lightweight birch-sap lotion that layers fast and rarely feels greasy; YMMV on acne.
What the community says
A thin gel-lotion with birch sap, glycerin, dimethicone, panthenol, allantoin, and sodium hyaluronate. People grab it for oily or combination skin, daytime layering, and retinoid routines. Acne-prone users still report occasional breakouts and a few barrier freak-outs.
