Panthenol is the alcohol analog of pantothenic acid (vitamin B5) that converts to pantothenic acid in the skin, acting as a humectant that helps retain moisture and supports skin barrier function and wound healing. It is widely used in moisturizers, after-sun products, and hair care for its soothing and hydrating properties.
