Alpha-hydroxy acids (AHAs) are chemicals that come from fruits, milk, and sugar cane. They are used in skincare products to make your skin look better. AHAs work by removing dead skin cells and helping your skin to look brighter and smoother. They can also help to make your skin more elastic and firm. AHAs are safe for most people to use, but they can sometimes cause redness or irritation. AHAs are found in many skincare products, such as cleansers and creams.
