Maltobionic acid is part of the PHA family and is non-irritating. This patented ingredient is known as a “Bionic Acid” and is derived from natural sugars. It helps to reduce the appearance of lines and wrinkles, discoloration, enlarged pores and roughness through gentle exfoliation. Maltobionic acid is a potent antioxidant that has been shown to target naturally-occurring, skin degrading enzymes to help maintain a youthful look. Maltobionic acid is medically coveted because it is a super powered chelator and humectant, protecting skin and attracting moisture to the delicate barrier for added hydration boosting and comfort. Maltobionic acid is the key choice for very dehydrated, parched and dry skin types.
