INGREDIENT OVERVIEW

Lactic Acid 80% Solution

Lactic acid is an alpha hydroxy acid (AHA) used in cosmetic formulations for pH adjustment, exfoliation, and skin renewal.

It is commonly used in serums, toners, creams, and exfoliating treatments where controlled resurfacing and improved skin texture are desired. In lower concentrations, it is used to adjust pH and support formulation stability.

In formulation, lactic acid helps refine skin texture and improve product performance while contributing to a smoother, more even skin appearance.

Our grade is supplied as a cosmetic-grade liquid with controlled assay and low impurity profile, supporting consistent formulation performance.
