What ingredient is commonly found in exfoliants?

1. Vitamins C and E

2. Peptides

3. Alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs)

4. Natural oils

The correct answer is: Alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs)

Exfoliants are skincare products designed to remove dead skin cells from the surface of the skin, promoting a smoother and more radiant complexion. Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are widely recognized as effective ingredients in exfoliants. AHAs, such as glycolic and lactic acid, are water-soluble and work primarily on the skin's surface, helping to slough off dead skin cells and improve skin texture and tone. BHAs, on the other hand, are oil-soluble, allowing them to penetrate deeper into the pores, making them particularly effective for oily or acne-prone skin. This ability to exfoliate both the surface and inside the pores helps to reduce the formation of acne and can improve overall skin clarity. While vitamins and natural oils can contribute beneficial properties to the skin, they do not serve the primary purpose of exfoliation. Peptides are more targeted towards skin repair and collagen production rather than exfoliation. Therefore, AHAs and BHAs are specifically recognized and utilized for their exfoliating properties in skincare formulations.
