Science
Mechanism of Action
As an ester of Lactic Acid, Methyl Lactic Acid functions as an alpha hydroxy acid, promoting accelerated cellular turnover and aiding in the gentle removal of accumulated dead skin cells from the epidermal surface. This process facilitates exfoliation, revealing fresher, smoother skin. Concurrently, it imparts moisturizing benefits, helping to draw and retain hydration within the skin. Beyond its direct skin benefits, Methyl Lactic Acid is extensively utilized as a solvent, improving the dispersion and efficacy of other ingredients within a formulation.

Safety
Safety Profile
The CIR Expert Panel designates Methyl Lactate as safe for cosmetic use at concentrations not exceeding 10%, provided the final product pH is at least 3.5. Crucially, products must be formulated to avoid increasing sun sensitivity, or clear directions for daily sun protection must be provided. While its general sensitization risk is unknown, its AHA ester nature necessitates careful formulation regarding sun exposure. Methyl Lactate is also recognized by the FDA as Generally Recognized As Safe (GRAS) for direct food additive use and meets Food Grade specifications.
