What does Xylitol do for skin?

Xylitol, a sugar alcohol, acts as a humectant by attracting and binding water molecules from the environment and deeper epidermal layers, thereby increasing skin hydration and reducing transepidermal water loss. It also supports skin barrier function by promoting the synthesis of ceramides and enhancing the expression of aquaglyceroporin 3 (AQP3) in keratinocytes, facilitating water and glycerol transport crucial for maintaining skin moisture and integrity.

Typical concentration: 1-10% (most formulas use 2-5%)

Is Xylitol safe?

The Cosmetic Ingredient Review (CIR) Expert Panel assessed Xylitol and found it safe as a cosmetic ingredient in current practices of use and concentration. It is generally well-tolerated and considered non-irritating and non-sensitizing for topical application.
