What is an example of a chemical exfoliant?

• A. Salicylic acid
• B. Alpha hydroxy acid (AHA)
• C. Retinol
• D. Glycolic acid

Answer: (B)

Alpha hydroxy acid (AHA) is recognized as a chemical exfoliant because it works by loosening the bonds that hold dead skin cells together on the surface of the skin. This process promotes the shedding of these dead cells, revealing fresher, healthier skin beneath. AHAs, such as glycolic acid, lactic acid, and citric acid, help to improve skin texture, reduce dullness, and enhance radiance. While salicylic acid is also a chemical exfoliant, specifically classified as a beta hydroxy acid (BHA), the focus of this question is on AHAs. Retinol is a form of vitamin A primarily known for its ability to promote cell turnover and reduce signs of aging but is not typically categorized strictly as an exfoliant. Glycolic acid falls under the category of AHAs as well, but in the context of the question, alpha hydroxy acid is the broader classification that encompasses glycolic acid and highlights its role in chemical exfoliation.
