Akin to AHAs and BHAs, there is a new family member in town: A gentler version of the well-known alpha and beta hydroxy acids, polyhydroxy acids or PHAs. Skin care regimens are not complete without effective exfoliation to remove dead skin cells and buildup on the skin’s surface. However, many individuals experience irritation and dry skin when incorporating traditional chemical exfoliants, such as synthetic AHAs or BHAs, into their daily routines. PHAs can provide a gentle alternative for individuals with more sensitive skin types. PHAs like lactobionic acid are typically derived from lactose/milk and are not considered vegan. AC Water Kefir PHA delivers a vegan source of gluconic acid from water kefir to enhance natural skin beauty by promoting collagen synthesis and cellular renewal.
