Derived from plant extracts, lactobionic acid, a polyhydroxy acid (PHA), is a mild exfoliant that smoothes and resurfaces without causing irritation or redness, making it suitable for all skin types, even for those with sensitive skin. This is because PHA acids have a larger molecular size, meaning they exfoliate much more gently than AHA’s, as well as not increasing the skins sensitivity to sun. Through exfoliation, cellular turnover is increased for a fresher, more even toned complexion. Lactobionic acid is also a strong humectant, as it has the ability to attract and retain moisture within the skin. This ensures that the skin stays hydrated and skin cells are plumped which firms the skin whilst reducing the appearance of fine lines and wrinkles.
