An antioxidant used in cosmetic applications should have the capability to efficiently quench free radicals on the surface of the skin. In this context, the studies performed by Sabinsa Corporation revealed the superior free radical scavenging ability of THC. In a standard test procedure known as DPPH (1,1 diphenyl-2-picrylhydrazyl)-radical scavenging method, Curcuminoids and THC were shown to be effective antioxidants. Their efficacy is concentration dependent, with THC being more effective even at lower concentrations.

Tetrahydrocurcuminoids are polyphenolic compounds with parahydroxyl functional groups and keto functional groups that participate in the antioxidant and chemopreventive actions.
