Our RENUAdvanced®️ Foaming Cleanser contains PHA, but what is it exactly and is it safe? First off, at ASEA, we wouldn't put anything in our ingredients that aren't safe for you. Polyhydroxy acids (PHAs) are chemicals known to exfoliate epidermal layers without going beyond the basal layer. This helps maintain the integrity of the epidermal barrier, making it accessible to those with sensitive skin. There are also excellent moisturizing and antioxidant properties in Gluconolactone and Lactobionic PHAs, giving you a hydrating and smoothing experience. It's not magic—it's science.
