How do Alpha Hydroxy Acids function in skin treatment?

Alpha Hydroxy Acids (AHAs) are a group of organic compounds known for their ability to exfoliate the skin. They function primarily by dissolving the bonds that hold dead skin cells together on the surface of the skin. This process helps to promote cell turnover, allowing newer, healthier skin cells to emerge. The result is a smoother texture and a more radiant appearance.

Choosing the correct answer highlights an important aspect of skincare treatments. While AHAs are often associated with hydration due to their ability to improve skin texture, their primary mechanism is not about adding moisture directly but rather about removing dead skin cells. This process helps to unclog pores and can also lead to improvements in conditions such as acne, hyperpigmentation, and fine lines.

In contrast, options involving tightening the skin or blocking UV rays do not accurately reflect the scientific basis of how AHAs operate. While some treatments may offer tightening effects or sun protection, AHAs specifically target the exfoliation of skin layers.
