AHAs (or Alpha Hydroxy Acids) are chemical exfoliants for the skin.
AHAs are made from natural sources like sugar cane, sour milk and grapes.
Being water-soluble acids, they help to speed up cell turnover by dissolving the glue-like substance that holds the dead skin cells together. As a result, the skin can shed more effectively, which leads to brighter, smoother, and more even-toned skin.
As they are water-based, they can also help to hydrate the skin.
The most used AHAs in skincare are:
- Glycolic Acid
- Lactic Acid
- Mandelic Acid
