How do enzymes in exfoliators affect dead skin cells?

Enzymes in exfoliators play a significant role in skin care by breaking down the bonds between dead skin cells and the living cells underneath. This process is sometimes referred to as "digesting" the dead skin cells, making it easier for them to be shed naturally from the skin's surface. Enzymatic exfoliation is often gentle and effective, allowing for improved skin texture and tone without the physical abrasion caused by some mechanical exfoliants.

The other options do not accurately describe the primary function of enzymes in exfoliation. While they do facilitate the shedding of dead skin cells, they do not completely remove them; instead, they help in the natural process of exfoliation. Enzymes do not directly promote keratin production, nor do they provide protection against UV damage. These functions belong to other components and processes in skin care and physiology.
