Lactobionic acid is a polyhydroxy acid (PHA), derived from lactose, which is a sugar found in milk. It is distinguished by its larger and gentler molecularstructure compared to AHAs and BHAs. Due to its larger molecular size, Lactobionic acid forms a film on the skin's surface, reducing water loss and increasing hydration. It does not penetrate the skin, so it is an excellent ingredient for exfoliating and skin conditioning sensitive skin. Its primary advantages are predominantly associated with enhancing skin moisturization, promoting a more uniform tone, and improving overall clarity.
