Also known as: Glycerol, Glycerine
Glycerin is one of the most well-researched and widely used humectants in skincare. It draws water from the environment and deeper skin layers into the stratum corneum, improving hydration and skin barrier function. Effective at concentrations as low as 1%, it is suitable for all skin types including sensitive and acne-prone skin.
Comedogenicity ratings are based on the rabbit ear assay model. Individual skin responses vary. See our article on comedogenicity ratings for context.
