What Is AHA - Alpha Hydroxy Acid?
Alpha Hydroxy Acids (AHAs) are a family of water-soluble acids derived from natural sources like fruits, milk, and sugar cane. The most common AHAs include glycolic acid (sugar cane), lactic acid (milk), mandelic acid (almonds), and citric acid (citrus fruits).
These acids work by dissolving the bonds between dead skin cells on the surface, promoting exfoliation and revealing fresher, more radiant skin beneath. Regular use can improve texture, tone, and the appearance of fine lines.
