Vitamin B5
Vitamin B5, also known as panthenol, is a popular skincare and haircare ingredient that helps hydrate, soften and soothe. It is widely used in UK moisturisers, serums, conditioners and masks because it absorbs easily and leaves skin and hair feeling smooth and healthy-looking.
How it works in skincare
In cosmetics, Vitamin B5 is converted into pantothenic acid on the skin where it acts as a humectant, drawing moisture into the upper layers and helping to strengthen the skin’s natural barrier. It also improves the feel and spreadability of formulations, leaving a silky, non-greasy finish that makes it ideal for both leave-on skincare and rinse-off hair products.
