What role do enzymes play in skincare?

Enzymes play a crucial role in skincare, particularly in the context of exfoliation. Their primary function in this area is to help break down and remove dead skin cells from the skin's surface. This process is effective because enzymes can target specific proteins in the outer layer of skin, aiding in the natural shedding process without the need for harsh physical scrubs. By facilitating gentle exfoliation, enzymes can help promote a smoother and more radiant complexion while also allowing better absorption of other skincare ingredients.

In contrast, while some enzymes may indirectly contribute to moisture retention or have supporting roles in healing through improved skin texture, their primary and most significant impact in skincare remains their ability to break down dead skin cells. Thus, choice B accurately highlights their fundamental role in exfoliation.
