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.

Sepiwhite MSH powder  is a lipoaminiacid and is primarily an alpha-MSH antagonist and tyrosinase activity inhibitor.Alpha-MSH is a key regulator of
melanotropin (skin pigmentation) while tyrosinase is an enzyme which is responsible for melanin production. Inhibition/reduction of these activities
thereby results in skin lightening/brightening and the overall improvement of skin tone.
