What is it?

Gallic acid is a natural phenolic compound found in many plants (oak bark, witch hazel, sumac). Diglucosylation improves its water solubility and stability. It inhibits tyrosinase and scavenges free radicals, making it effective for both brightening and antioxidant protection.

Used in brightening serums and antioxidant products to deliver stable polyphenol antioxidant protection and reduce melanin overproduction for a more even skin tone.
