Panthenol

Panthenol (pro-vitamin B5) — (See Vitamin B) acts as a penetrating moisturizer. Studies indicate that when topically applied, panthenol penetrates the skin and gets converted into pantothenic acid, a B complex vitamin. It imparts a non-irritating, non-sensitizing, moisturizing, and conditioning feel and promotes normal keratinization and wound-healing. Panthenol protects the skin against sunburn, provides relief for existing sunburn, and enhances the natural tanning process. Panthenol’s humectant character enables it to hold water in the product or attract water from the environment, resulting in a moisturizing effect. It enhances skin suppleness, and claims are that it also acts as an anti-inflammatory agent.
