Lactic Acid

What is Lactic Acid?

Lactic Acid is a active ingredient that provides targeted treatment benefits through biochemical interactions. It provides exfoliation benefits. Results are typically seen in the short-term (days to weeks). It is most effective at a concentration of 5-10% (daily), 20-60% (professional peels). For maximum effectiveness, this acid works best in formulations with the correct pH range.
