Lactobionic Acid

A PHA (poly hydroxy acid) that acts as a gentle exfoliator, while simultaneously maintaining the skin’s barrier by hydrating and acting as an antioxidant against free radicals. Its exfoliating function helps to prevent buildup, resulting in a brighter, more even skin tone.

This PHA, whose name sounds like a superhero, truly is a skincare hero. Its large, gentle molecular structure limits skin penetration and allows it to stay at the surface of the skin, where it creates a beautiful, smooth surface level of exfoliation. It is the perfect complement to the tiny glycolic acid molecules—another skincare superhero–that dive deep into the skin. PHAs are also hydrating, plumping humectants, meaning they are water magnets that help to keep the skin hydrated and prevent collagen breakdown, even when you're rapidly turning over your skin.
