Panthenol is a commonly used ingredient in skin and hair care products. It has moisturizing, soothing and regenerating properties. Panthenol is able to penetrate the skin and hair, where it converts to vitamin B5 (pantothenic acid), an essential nutrient for healthy skin and hair. It is often used in moisturizers, lotions, hair products, and after-sun products to help hydrate skin, soothe irritation, promote healing, and improve hair texture. Panthenol is considered a mild and well tolerated ingredient suitable for all skin and hair types.
