1.Tyrosine is a catalytic substrate for the function of tyrosinase monophenolase, and is the main raw material for the final formation of eumelanin and pheomelanin. In the research and development of whitening cosmetics, the synthesis of tyrosinase structural analogues that compete with tyrosine can also effectively inhibit the production of melanin.
2.Vitiligo patients eating foods containing tyrosine can promote the formation of melanin and reduce vitiligo symptoms.
