What is a common benefit of using enzyme exfoliants?

The choice indicating that enzyme exfoliants remove dead skin cells is the most accurate because enzymes work by breaking down the proteins in the keratin of the stratum corneum, the outermost layer of the skin, facilitating the shedding of dead skin cells. This process helps to refine the skin's texture, improve clarity, and promote a more radiant appearance. Enzyme exfoliants can be particularly gentle, making them suitable for a variety of skin types, including sensitive skin.

While other choices may touch on beneficial effects that can be associated with exfoliation or general skin care, they do not directly define the primary function of enzyme exfoliants. Promoting hydration can be an outcome of improved skin health but is not a direct mechanism of how enzymes function. Similarly, the glowing effect is often a result of overall skin renewal that follows exfoliation, and lightening of the skin is not a typical claim related to enzyme exfoliation products. Therefore, the key function of enzyme exfoliants remains the removal of dead skin cells.
