10/10

Concern level

High concern

Glycerin (glycerol) is a small, highly effective humectant and one of the most established moisturizing ingredients in skincare. It draws water into the stratum corneum, supports barrier function, and improves skin softness and elasticity. It is widely used in cleansers, moisturizers, serums, and therapeutic formulations because it is well tolerated and effective across skin types.
