Which product, consisting of AHA, is specifically used to remove dead skin cells?

The choice of a chemical exfoliant, particularly one that consists of alpha hydroxy acids (AHA), is correct because these products are specifically formulated to facilitate the removal of dead skin cells from the skin's surface. AHA works by loosening the bonds between dead skin cells, allowing them to slough off more easily, which helps in promoting cell turnover and revealing fresher skin underneath.

Moisturizers, while essential for hydrating the skin, do not possess the properties needed to actively exfoliate or remove dead skin cells. Instead, they primarily serve to lock in moisture and keep the skin barrier healthy.

Physical exfoliants involve the use of abrasive materials to manually remove dead skin cells. However, they can sometimes lead to irritation or micro-tears if not used gently, and they do not chemically dissolve the bonds between skin cells like AHAs do.

Hydrating creams focus on moisture retention rather than exfoliation. They usually contain humectants or emollients that nourish and hydrate the skin, rather than addressing the removal of dead skin cells.

Therefore, chemical exfoliants are distinct in their function and effectiveness in promoting exfoliation, making this choice the most suitable for the question.
