Tetrahydrodiferuloylmethane, also known as tetrahydrocurcumin (THC), is an organic antioxidant and soothing compound belonging to the family of curcuminoids.
Curcuminoids make up a major part of turmeric, an Indian medicinal and culinary plant that many are familiar with. Unlike other turmeric derivatives that have a vibrant yellow color, THC is a white powdered extract.
New research suggests that it may have some anti-pigment action on human skin, but further research is necessary to confirm this.
