Enzymes are substances that catalyze chemical reactions, and in the context of skin care, certain enzymes are effective at dissolving keratin proteins found on the surface of the skin. Keratin is a tough protein that can contribute to the buildup of dead skin cells, leading to a rough or dry texture. Specific enzymes, such as papain (derived from papaya) and bromelain (from pineapple), can break down this keratin, promoting exfoliation and ultimately resulting in smoother, more refined skin.

This enzymatic action helps to clear away dead skin and assist in the renewal of the skin's surface, making it a vital ingredient in products intended for chemical exfoliation. In contrast, while retinoids are known for their ability to stimulate cell turnover and improve skin texture, they do not specifically dissolve keratin on the surface. Moisturizers primarily serve to hydrate and maintain moisture balance in the skin, and humectants are agents that attract water to the skin but do not have an exfoliating effect on keratin proteins. Thus, enzymes are particularly recognized for their unique role in breaking down keratin proteins, making them the correct choice.
