What is a primary benefit of using alpha hydroxy acids in skincare?

The primary benefit of using alpha hydroxy acids (AHAs) in skincare is that they help to remove dead skin cells. AHAs are water-soluble acids derived from fruits, and they work by loosening the bonds between dead skin cells on the surface of the skin, promoting exfoliation. This process not only sloughs off the uppermost layer of dead skin but also reveals fresher, healthier skin underneath, improving skin texture and radiance. Exfoliation contributes to a more even skin tone and can enhance the absorption of other skincare products.

While other benefits like stimulating collagen production or reducing inflammation may also occur with certain acids, the primary and most well-recognized effect of alpha hydroxy acids is their exfoliating property, making option B the most accurate in this context.
