How does the loss of a layer of dead cells and increased collagen improve the appearance of the skin?
A thick layer of dead cells on the surface of the skin gives the complexion a rough, dull appearance. When these cells are removed, a fresh new layer is exposed. This layer has a smoother texture and a more uniform color. At the same time, deeper layers of the skin are stimulated to produce new collagen and elastic fibers which lend support to the overlying epidermis (surface skin cells). Recent scientific studies show that continued use of Alpha Hydroxy Acids over time can cause the top layer of living cells to actually become plumper, creating a more youthful tightening of the skin. In some AHA users, this tightening can even lead to a reduction in fine wrinkles or superficial scars.
