Alpha hydroxy acids (AHAs) may be irritating to skin for many sensitive skin patients. Gluconolactone and lactobionic acids are types of polyhydroxy acid (PHA) that are as effective as AHAs but less irritating . Polyhydroxy acids are often combined with vitamin A ,and Vitamin E and Vitamin B resulting in rich emollient products that help hydrate the skin, reducing fine lines and wrinkles with gentle exfoliation and improve uneven pigmentation and sun damage.
