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.
