Panthenol, also known as provitamin B5, is a water-soluble vitamin. In the skin, panthenol is converted to pantothenic acid, which is an important component of coenzyme A. Coenzyme A is involved in many cellular processes in the body, including the production of energy and the synthesis of fatty acids. Panthenol is beneficial for the skin in several ways. It helps to improve skin hydration, reduce inflammation, and promote wound healing. Additionally, panthenol can help to soothe and protect the skin, making it a beneficial ingredient for people with sensitive or irritated skin. Found in: Hydration Mask
