Thiamidol bụ ihe mgbochi pigmenti emepụtara ka emechara nyocha ihe karịrị afọ iri. Ihe ọhụrụ a na-eme ihe na-arụ ọrụ na-egosi mgbanwe n'ime nyocha na mwepụ ntụpọ pigmenti - mmetụta nke thiamidol bụ nke ezubere iche ma gbanwee ya, ya mere egosipụtara na ngwaahịa ndị ahụ dị irè ma dị mma. Tupu nyocha a, ọ gaghị ekwe omume ịmepụta ihe na-arụ ọrụ nke na-arụ ọrụ nke ọma. N'ụzọ megidere nke ahụ, ruo mgbe ahụ, ọ ga-ekwe omume igbochi nkesa site na dịka niacianamides na ihe ndị ọzọ na-arụ ọrụ. Niacianamide naanị abụghị onye na-egbochi tyrosine mmadụ ma na-akwụsịtụ nnyefe nke melanin.
