Alpha hydroxy acids (AHAs) are a group of natural acids commonly found in fruits and milk. They are often used in skincare products for their exfoliating properties, helping to remove dead skin cells and promote cell turnover. This can lead to smoother skin texture and a brighter complexion. AHAs, such as glycolic acid and lactic acid, are water-soluble and work primarily on the skin's surface. They can also improve the appearance of fine lines, sun damage, and uneven skin tone. Regular use of AHAs can enhance overall skin health and radiance.
