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.
Lactic Acid, when compared to Glycolic or Citric Acids, shows greatly reduced irritancy while offering pronounced efficacy in exfoliating and skin rejuvenating formulations. 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:
- enhanced skin lightening effects
- improved collagen and elastin synthesis.
- accelerated exfoliation and cell renewal.
- removal of the corneocyte or "dead/horny" layer of skin to reveal a fresher, more youthful appearance.
- clear non viscous liquid
- characteristic acid (fermentation) odor
- water soluble
- store tightly sealed away from direct heat
- shelf: 2yrs. when properly stored
- added at cool down
- 0.2 to 10.0%
- gentle pH control
- skin / body care
- gentle exfoliation
It's important to note that the pH of the final formulation is just as important as the concentration level. At home products should be formulated within the usage range of 10 to 12%, with a pH between 4.0 and 4.5.
