AHA, stands for alpha-hydroxy acid. At Eucerin, we use the AHA Glycolic acid, which is derived from sugar cane. This peeling acid has a very small molecular size, makes skin smoother, more even and opens pores, Without compromising on barrier structures of the skin. 

It promotes exfoliation by reducing cell adhesion in the epidermis and increasing cell turnover. Furthermore it increases biosynthetic capacity of collagen and builds support structure in the dermal matrix to reduce wrinkles and fine lines.
