Lactobionic acid can be considered as a disaccharide formed from gluconic acid and galactose. It is a sugar acid. It can also be formed by oxidation of lactose. It comes as a solid, crystalline white powder. 

Use & Benefits

Lactobionic acid has many hydroxyl groups, which gives it a unique property of a humectant. It means it can draw moisture from the surroundings for the skin. It is also used as an antioxidant, which can fight against the damaging oxygen molecules as well as free radicals. It prevents the skin from becoming structurally altered by those radicals and thus prevents formation of fine lines and wrinkles and premature aging of the skin. Because of many more -OH groups involved in the structure of the lactobionic acid, it cannot penetrate into the skin, which helps skin experience less irritation as compared to AHAs. So, it gives a good peeling effect with no irritation, which can be considered a preferable characteristic in a peeling agent. It also helps to prevent photoaging. It is used mainly in exfoliating or peeling preparation.
