Polyhydroxy Acids are Alpha Hydroxy Acids with multiple (i.e., poly) hydroxy groups on the molecule. The additional hydroxys attract water making PHA compounds more hydrating and moisturizing than conventional AHAs. PHA compounds are also antioxidant chelators that have been found to be gentle to skin without the stinging and burning that may accompany AHA use on sensitive skin.
