A salt or ester form of glycollic acid, used in skincare products and chemical processes.
From 'glycol' (a two-carbon alcohol) + '-ate' (suffix for salts and esters). This term developed as organic chemistry classified different forms of glycol-based compounds.
Glycollic acid and its salts (glycollates) are alpha hydroxy acids that cosmetic companies love because they gently dissolve dead skin cells—they're basically controlled acid peels you can buy at the drugstore!
