The type of skin treatment that primarily involves the use of acids is a chemical peel. This treatment works by applying a solution containing various acids, such as alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs), to the skin. These acids help exfoliate the outer layers of the skin, promoting the shedding of dead skin cells and encouraging the regeneration of new skin. The acidity of the peel can vary depending on the desired depth of exfoliation and the specific skin concern being addressed, such as acne, hyperpigmentation, or fine lines.

Chemical peels are effective for improving skin texture and tone, reducing the appearance of acne scars, and treating sun damage. The use of acids is a defining characteristic of this treatment, setting it apart from other options like microdermabrasion, which is a mechanical exfoliation method, facials scrubs that rely on physical exfoliants, and hydration treatments that focus on moisturizing the skin rather than exfoliating it.
