What is Panthenol?
Panthenol — also known as pro-vitamin B5 or dexpanthenol — is a stable alcohol form of pantothenic acid (vitamin B5). When applied to the skin it converts to pantothenic acid, which the body uses to synthesise coenzyme A and support cellular repair. Topically, panthenol is a humectant, an anti-inflammatory and a wound-healing accelerator all in one molecule. It has a long history of medical use in burn and wound creams.
