Lactic Acid 88% is a high-strength alpha-hydroxy acid (AHA) widely used in skincare formulations for its powerful exfoliating and pH-adjusting properties. Naturally derived from fermented sugars, it gently dissolves dead skin cells, promoting smoother texture, improved tone, and a brighter complexion. Ideal for chemical peels, serums, masks, and exfoliating treatments, this concentrated form offers maximum potency for professional and advanced skincare applications.
In addition to its cosmetic benefits, 88% Lactic Acid is also used in industrial, food-grade, and pharmaceutical applications for pH regulation and preservation. This versatile ingredient is suitable for formulators seeking an effective exfoliant or functional acid in both personal care and technical products. Dilution is required before use in cosmetic formulations—always follow proper handling guidelines.
