ProVitamin B5
Provitamin B5, also known as panthenol, is a popular skincare and haircare ingredient that converts into vitamin B5 when applied to skin or hair. It is prized for its ability to attract and hold moisture while soothing and conditioning. You will find it in everything from moisturisers and serums to shampoos and conditioners.
How it works in skincare
In cosmetics and skincare, provitamin B5 penetrates the upper layers of the skin and hair shaft where it is converted into pantothenic acid. It functions as a humectant, drawing water into the skin or hair, and forms a light protective film that helps prevent moisture loss. This dual action leaves skin feeling soft and supple and hair smoother, shinier and easier to manage.
