Overview

Mannitol is a sugar-derived alcohol with a mildly sweet taste. Similarly to sugars, it is mainly used for its ability to bind and retain water to the surface of the skin (which hydrates it).

According to dermatology science, mannitol is also an antioxidant and works well when combined with hyaluronic acid. Another study found that it has mild soothing effects on capsaicin-induced pain and burning of the skin.
