What Is Xylitol?

Xylitol is a natural sugar alcohol (polyol) found in birch trees and many fruits that functions as an exceptional humectant and prebiotic in skincare. It binds water more effectively than glycerin at low humidity levels, providing sustained hydration even in dry environments. Also selectively feeds beneficial skin bacteria while inhibiting pathogenic strains, supporting a healthy skin microbiome. Provides a pleasant cooling sensation on application.
