What Is Diglucosyl Gallic Acid?
Diglucosyl gallic acid is a synthetic antioxidant that is a derivative of benzoic acid (another name for this ingredient is trihydroxy benzoic acid alpha-glucoside). According to its manufacturer, it works primarily as a skin brightening agent and fights the root causes of discolorations and redness.
Limited research supports these claims, less than what we nornally like to see to make an ingredient one worthy of adding to your routine. Still, what published studies exist make diglucosyl gallic acid an ingredient to watch in the future. Usage levels for visible results on hyperpigmentation and redness range from 1–4% when blended in a water and glycerin carrier base.
