What does a chemical peel do to the skin?

1. It hydrates the skin

2. It removes dead skin cells

3. It exfoliates the skin

4. It lightens pigmentation

The correct answer is: It removes dead skin cells

A chemical peel primarily works by removing dead skin cells from the outer layer of the skin. It involves the application of a chemical solution that causes the top layers of the skin to exfoliate and eventually peel off. This process reveals fresher, smoother skin beneath and can help improve the overall texture and appearance of the skin. While chemical peels can contribute to exfoliation, which is the process of sloughing off dead skin, the specific action of removing dead skin cells is a key focus. The treatment can also help in reducing various skin imperfections, such as fine lines, sun damage, and acne scars, by facilitating cellular turnover. In addition to removing dead skin cells, it’s important to note that chemical peels do not primarily function to hydrate the skin, although they can improve skin texture, which may lead to better moisture retention. They can assist in lightening pigmentation issues, but that is not their main action; rather, they create an environment that can contribute to improved pigmentation over time. Therefore, the core benefit of a chemical peel aligns most closely with the removal of dead skin cells.
