Tris(Tetramethylhydroxypiperidinol) Citrate is a hindered amine (HALS-type) antioxidant and metal-chelating agent used in skincare to protect formulations from oxidative degradation and to help neutralize free radicals. It functions primarily as a stabilizer and secondary antioxidant rather than a primary treatment active.
