Updated October 30, 2026
Birch sap hydrator dries down nongreasy for tretinoin routines; breakout risk remains.
What the community says
A lightweight lotion built around birch juice, glycerin, sodium hyaluronate, panthenol, and allantoin, with dimethicone for slip. It suits oily, combination, and tretinoin-irritated skin needing hydration without an oil slick, though dry eyes and acne-prone users report problems.
