2. To moisturize the skin

3. To prevent acne

4. To enhance skin color

The correct answer is: To promote cell turnover

The primary benefit of using a chemical exfoliant is to promote cell turnover. Chemical exfoliants, like alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs), work by breaking down the bonds between dead skin cells, allowing them to be shed more easily from the surface of the skin. This process not only helps remove dead skin but also stimulates the production of new skin cells, leading to a fresher and more radiant complexion. Promoting cell turnover is particularly important as it contributes to the skin's overall health and appearance. As we age, cell turnover slows down, leading to a build-up of dead skin cells that can make the skin look dull, uneven, and contribute to the formation of fine lines and wrinkles. By using a chemical exfoliant, individuals can enhance the skin texture and brightness, reduce signs of aging, and improve the effectiveness of other skincare products. While other benefits like moisturizing, preventing acne, and enhancing skin color can be associated with specific formulations or ingredients within certain products, they do not capture the primary function of chemical exfoliants, which is to facilitate the natural process of shedding and renewing skin cells.
