Lactic Acid is a gentle Alpha Hydroxy Acid (AHA) widely used in Korean skincare (K-beauty) for its ability to exfoliate, brighten, and hydrate the skin. Naturally derived from milk and fermented sources, Lactic Acid works by removing dead skin cells on the surface while drawing moisture into the skin, making it less irritating than stronger exfoliants like Glycolic Acid.
In K-beauty formulations, Lactic Acid is often paired with hydrating ingredients such as Hyaluronic Acid, Beta Glucan, or Panthenol, as well as soothing botanicals like Centella Asiatica. This ensures a balanced exfoliation that leaves skin smoother, brighter, and more supple without over-drying.
