What it does
Xylitol is a sugar alcohol used in skincare as a humectant — it attracts and binds water, helping keep the skin surface hydrated and a formula from drying out. It is often combined with related sugars and is well tolerated. We list its water-binding role here; any specific microbiome or barrier claims belong with their own cited evidence.
