Its reduced molecular weight favors its absorption in the stratum corneum. Its activity is linked to the ability to reduce the forces of cohesion among the corneocytes by direct action on the desmosomes. The exfoliation of the upper layer of the epidermis and the consequent increase in the speed of cellular turn-over, produces an increase in the activity of fibroblasts and the production of collagen and elastin.
Lactic acid is an organic acid belonging to the category of alpha hydroxy acids. Lactic acid has properties of skin exfoliant, pH regulator and skin conditioning. After the treatment of cutaneous exfoliation, cell turnover is accelerated and glycosaminoglycan synthesis is stimulated, as a result the skin appears brighter and more hydrated.
The salicylic acid, also called beta-hydroxy acid (bha) has exceptional keratolytic properties, it causes a controlled desquamation with consequent activation of the epidermis renovation. It has a strong comedolytic, bactericidal and sebumregulating action. It is particularly indicated for the treatment of greasy/oily skins.
