AHA, or Alpha Hydroxy Acid, is a group of chemical compounds commonly used in skincare for their exfoliating properties. AHAs, such as glycolic acid and lactic acid, work by gently removing dead skin cells from the surface of the skin, leading to improved texture and a more even complexion. They can reduce the appearance of fine lines, acne scars, and sun damage, resulting in smoother, brighter, and rejuvenated facial skin. Additionally, AHAs can stimulate collagen production and enhance the absorption of other skincare products, making them an essential component of many skincare routines.
