additional info

Lactobionic acid is a larger molecule than glycolic acid, resulting in gentler exfoliation and less irritation. It also increases the deposition of glycosaminoglycans, improves elastic fiber quality, and induces collagen gene expression, providing antiaging benefits. Lactobionic acid can be used in leave-on toners, face masks, and exfoliating pads. It is important to wear sunscreen when using lactobionic acid, as it can make skin more sensitive to sunlight.
