Lactic Acid Versus Glycolic Acid
• Studies done by Walter Smith, PhD, Comparing the efficacy
of a 4% Glycolic Acid Solution vs. 4% Lactic Acid solution (both at a pH
of 3) indicate that Lactic Acid was not only less irritating but slightly more effective
than Glycolic Acid in stimulating cell turnover. While it is thought that both Glycolic Acid
and Lactic Acid affect the layers in the same manner as described above, it should be noted that there are additional beneficial effects unique to Lactic Acid. These include
an increase in dermal Glycosaminoglycans (GAGs-natural moisturizer), an increase
in ceramides (epidermal barrier lipids) and improved water barrier properties.
• Recent Studies have demonstrated that
5% Lactic Acid solution helps to reduce Hyperpigmentation.
