Glycerin and propanediol are humectants: ingredients that help attract and retain moisture at the skin surface.
In Daily Serum, they complement squalane and the formula’s selected botanical ingredients. Together, the moisturizing composition helps leave skin feeling soft, supple and comfortably hydrated.
