What is a skin peel?

A skin peel is a cosmetic treatment designed to remove the outer layer of skin, which can help improve texture, tone, and overall appearance. This process involves the application of a chemical solution that exfoliates the top layer, promoting the regeneration of new, healthier skin beneath. The outer layer of skin often contains dead cells, blemishes, and other imperfections, and by removing it, skin peels can effectively address issues such as acne scars, sun damage, and signs of aging.

In the context of the other options, while hydration, nutrient addition, and muscle relaxation can be important aspects of skincare and beauty treatments, they do not accurately define what a skin peel does. These options represent different types of treatments that do not involve the intentional removal of skin layers, which is the central function of a skin peel.
