Panthenol and Dexpanthenol are two names commonly used for the same ingredient. Panthenol converts into Pantothenic Acid (a B Complex Vitamin) in the skin and enhances skin regeneration and repair. When applied regularly, it has been proven to considerably improve symptoms of skin irritation such as dryness, roughness, scaling and redness.
Panthenol/Dexpanthenol is also an effective moisturizer. It improves hydration in the outermost layers of the skin and helps to reduce transepidermal water loss.
