Epigallocatechin Gallatyl Glucoside description

Epigallocatechin gallatyl glucoside is a derivative of a well-known, tea-derived antioxidant in the skin care world: epigallocatechin gallate (EGCG for short). It is obtained from the reaction of EGCG and glucose. While independent studies on epigallocatechin gallatyl glucoside are lacking, it is said to function as an antioxidant and skin-conditioning agent, which checks out given the ingredients it comes from. EGCG is backed by research for offering skin-soothing properties and helping to defend skin from the effects sun damage. It is the major antioxidant component of green tea. Glucose is a natural sugar that offers humectant and other skin-beneficial properties. Epigallocatechin gallatyl glucoside is touted by many brands as helping to address eye area concerns such as dark circles and under-eye bags; however we could not find peer-reviewed research to confirm these benefits. We can, however, theorize that this is a good anti-aging ingredient given its relationship to EGCG. Ingredient manufacturers suggest that due to its water solubility, epigallocatechin gallatyl glucoside may offer better formulary compatibility compared to traditional EGCG. At the time of this writing, the Cosmetic Ingredient Review has not conducted a formal safety assessment on epigallocatechin gallatyl glucoside. Our research did not reveal any known concerns about using this ingredient in skin care or personal care products. Usage levels range between 0.01–0.05%.
