Gallyl Glucoside description

Gallyl glucoside is a skin care ingredient produced by the reaction of the phenolic antioxidant compound gallic acid and sugar glucose. While independent studies on gallyl glucoside are lacking, it is said to function as an antioxidant and skin-conditioning agent with soothing properties, which stands to reason given the ingredients it comes from (gallic acid is an antioxidant and glucose is a humectant that supports skin’s microbiome). Of note, gallyl glucoside is often combined with epigallocatechin gallatyl glucoside and the preservative propyl gallate. Manufacturers claim this blend helps with concerns such as dark circles and eye puffiness. However, we could not find independent research that supports those claims. At the time of this writing, the Cosmetic Ingredient Review has not conducted a formal safety assessment on gallyl glucoside. Our research did not reveal any known concerns about using this ingredient in skin care or personal care products. Usage levels of this ingredient when part of a blend range from 0.01–0.05%.
