LACTOBIONIC ACID

Lactobionic acid is a next-generation AHA with a polyhydroxy structure (a so-called polyhydroxy acid). It is the oxidized form of lactose, which is derived from milk. Similarly to gluconolactone, lactobionic acid has larger molecule structure than AHAs and BHAs, therefore it is much more gentle for the skin, without causing the stinging and irritation associated with some AHAs. With lactobionic acid, only the shallow layers of the skin’s surface are receiving exfoliation, so it can be used daily and doesn’t need to be used at a low pH, which reduces irritation.

Research confirms lactobionic acid brings significant improvements in clinically graded parameters, a significant reduction in mild preexisting irritation, and significant increases in skin firmness and thickness. Although it belongs to the group of gentle exfoliators, it is also a humectant moisturizer that attracts and absorbs water to the skin as well as an antioxidant, soaking up skin-damaging free radicals. A research from 2016 confirmed that lactobionic acid absorbs free radicals generated by ultraviolet exposure. Due to the increased cellular turnover rate, it brightens the skin, evens out skin tone, reduces the appearance of fine lines and wrinkles. According to latest studies, lactobionic acid also aids in the lessening of scars and hyperpigmentation.
