UNDECYLENOYL PHENYLALANINE

Undecylenoyl Phenylalanine is a compound that includes amino acids and lipid residue, used to prevent skin cells from producing melanin pigmentation. Undecylenoyl Phenylalanine inhibits melanotropin, a melanin stimulator found in the skin. 

Melanotropin controls tyrosinase activity (tyrosinase being an essential enzyme in the production of melanin), melanin (eumalanin) synthesis and melanosome; therefore, by preventing the production of melanotropin, the pigmentation process is reduced or halted.
