Lactic Acid, is the L+ version, which is the natural form of this multifunctional cosmetic ingredient, produced through the fermentation of corn. The human body produces, and utilizes, this gentle acid to maintan it's optimal pH balance (Acid Mantle) used in the defence fungus and bacteria.

When used at concentrations of 2% or less, Lactic Acid will perform; pH regulating, antimicrobial, and moisture binding functions. When used at concentrations higher than 2%, Lactic Acid will perform the same functions as well as offering:

- accelerated exfoliation and cell renewal.
- removal of the corneocyte or "dead/horny" layer of skin to reveal a fresher, more youthful appearance.
