What is the main effect of alpha hydroxy acids (AHAs)?

Alpha hydroxy acids (AHAs) are primarily known for their ability to exfoliate the surface layer of the skin. This occurs because AHAs are water-soluble acids derived from fruits, and they work by loosening the bond between dead skin cells, facilitating their removal. This exfoliation process helps to reveal fresher, healthier skin beneath, improving texture and promoting a more radiant complexion.

The exfoliating nature of AHAs can also assist in the improvement of certain skin concerns, such as acne, dry skin, and signs of aging like fine lines. By promoting cell turnover, AHAs encourage the skin to shed old, damaged cells and generate new ones, which can contribute to a more youthful appearance.

While AHAs may offer some secondary benefits, such as moisturizing properties due to their ability to enhance skin hydration when used properly, their primary function is centered around exfoliation. This distinguishes them from other ingredients that may more directly target issues like pigmentation or skin firming.
