What does the term "chemical peel" refer to?

The term "chemical peel" specifically refers to a skin treatment utilizing chemical solutions, typically acids, to exfoliate the outer layers of the skin. This process can effectively improve skin texture, tone, and overall appearance by removing dead skin cells and stimulating cell renewal. Chemical peels vary in strength and depth, allowing estheticians and dermatologists to tailor treatments based on individual skin conditions and desired results. The primary goal of a chemical peel is to enhance the skin's brightness, clarity, and smoothness, making it a popular choice for those looking to address issues such as acne scars, hyperpigmentation, fine lines, and other skin imperfections.

The other options describe different aesthetic procedures or techniques that are not related to the chemical peel process. For instance, laser treatments involve energy-based methods that differ significantly from the acid-based approach of chemical peels, while professional makeup application and vitamin injection procedures have their own distinct purposes and techniques.
