Xylitol

Xylitol is a sugar alcohol used as  a substitute for sugar in the flavoring of many toothpastes and gums. Xylitol is found naturally in various berries, corn husks, oats, and mushrooms. Xylitol is used in cosmetics and personal care products not only as a flavoring agent in oral care products - which also utilize its plaque-reducing properties - but also as a humectant in other formulations. It is thought to help the skin retain its natural moisture and boost levels of hyaluronic acid, a natural lubricant that assists in collagen production. Xylitol is also thought to improve the skin's barrier function and increase ceramide (a natural hydrating compound) synthesis.
