It is chemically and functionally similar to AHAs (such as glycolic acid). The significant difference between lactobionic acid and AHAs is thatvlactobionic acid has a larger molecular structure, which limits its ability to penetrate the skin, resulting in less potential for sensitising side-effects. Polyhydroxy acids can also function as antioxidants and may promote some amount of improvement in skin’s surface strength.
