四肽-30——減少肌膚黑色素沉積,讓皮膚不再暗淡
簡介
四肽-30是一種四勝肽,通過抑制酪氨酸酶的基因表達進而減少酪氨酸酶的數(shù)量,和降低促黑激素α-MSH而抑制黑素細胞活化作用,減少黑色素生產(chǎn)。

機理
???四肽-30抑制酪氨酸酶的基因表達 ,減少酪氨酸酶的數(shù)量;通過降低促黑激素α- MSH和促黑激素前體POMC,抑制黑素細胞活化作用,減少黑色素生產(chǎn); 通過作用于人角質(zhì)形成細胞可顯著降低UVB誘導(dǎo)的白細胞介素IL-6,IL-8和TNF-α的mRNA表達,最重要是可降低POMC基因的表達, 減少炎癥后色素沉著和UVB誘導(dǎo)的皮膚色素沉著。
?Tetrapeptide-30 inhibits the gene expression of Tyrosinase and reduces the number of Tyrosinase; By reducing melanotropin levels α-? MSH and pro melanocyte hormone POMC inhibit the activation of Melanocyte and reduce melanin production; By acting on human Keratinocyte, it can significantly reduce UVB induced interleukin IL-6, IL-8 and TNF- α MRNA expression, most importantly, can reduce the expression of POMC genes, reduce post inflammation pigmentation and UVB induced skin pigmentation.
