Which ingredient in skincare products is commonly used for chemical exfoliation to treat acne?

  1. Alpha Hydroxy Acids (AHA)

  2. Beta Hydroxy Acids (BHA)

  3. Citric Acid

  4. Vitamin E

The correct answer is: Alpha Hydroxy Acids (AHA)

Alpha Hydroxy Acids (AHAs) are commonly used in skincare products for chemical exfoliation to treat acne. AHAs work by exfoliating the outer layer of the skin, unclogging pores, and promoting skin cell turnover, which can help reduce acne breakouts. Beta Hydroxy Acids (BHAs) are also effective for this purpose, but AHAs are specifically known for their ability to exfoliate and improve the overall texture and appearance of the skin. Citric Acid is more commonly used as an antioxidant and for brightening the skin tone, while Vitamin E is known for its moisturizing and antioxidant properties but is not specifically targeted for treating acne through chemical exfoliation.
