How does chemical exfoliation function?

Chemical exfoliation functions primarily by dissolving dead skin cells from the surface of the skin through the use of specific chemical agents, typically alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs). These acids work by breaking down the bonds that hold dead skin cells together, allowing them to be sloughed off more easily. This process promotes skin renewal and can improve the overall texture and appearance of the skin.

Dissolving dead skin cells is beneficial for a variety of reasons, including reducing the likelihood of clogged pores, enhancing the absorption of skincare products, and promoting a more radiant complexion. By effectively removing these top layers of dull, dead cells, chemical exfoliation can also stimulate collagen production and improve skin elasticity over time.

In contrast, the other options are not representative of the function of chemical exfoliation. While removing superficial layers of skin may seem related, it does not specifically capture the action of breaking down cellular bonds. Creating a physical barrier on the skin typically involves the application of moisturizers or occlusives, rather than the active dissolution of dead cells. Injecting moisture into the skin refers more to hydration techniques like the use of hyaluronic acid rather than exfoliation processes.
