What Is Panthenol?
Panthenol is a provitamin form of Vitamin B5 that penetrates the skin and converts into pantothenic acid, a nutrient your skin uses to support its own repair and barrier function. It has a long-standing reputation for calming the look of irritated or compromised skin.
Beyond its soothing properties, panthenol also acts as a humectant, helping the skin hold onto moisture, which is why it shows up across ASI's serums and cleansers rather than being reserved for a single sensitive-skin product.
