About Lactic Acid

Lactic Acid is an organic acid.[1] In cosmetics, it is used to buffer the formulation so its acidity does not change rapidly, attract moisture to the formulation and skin surface to help maintain hydration, and leave the skin surface feeling soft and smooth.[3] It is described as a colorless to pale yellow viscous liquid with no distinct odor, so the order and temperature used when mixing it with other liquid ingredients affect the uniformity of the finished product.[2]
