I-whiteting cosmetics kunye ne-pigmen metabolism

I-whiteting cosmetics kwayeI-pigmentImetabolism

I-Melanin Anabolism yahlulwe yangamaxesha ahlukeneyo. Izazinzulu zikholelwa ukuba kunokwenzeka ukuba ufunde iiarhente zomhlophe kunye nomsebenzi wexesha elahlukileyo le-metabolic.

(1) Inqanaba lokuqala le-melanin synthesis

① Ukuphazamisa ukhangelo kunye / okanye i-Glycossimty yeTyrosinase; ② ukuthintela abalawuli ngokusekwa kweTyrosinase; ③ Ukulawulwa kweposi kwe-tyrosinase.

(2) Ixesha le-melanin syntheshes
Njenge-enzyme ephambili kunye ne-enzyme yokunciphisa i-enzyme ye-melanin synthesis, i-tyntntinase inhibitors ngolona phando luphambili kunye nophuhliso okwangoku. Kuba uninzi lweearhente ezimhlophe ezinjenge-phenol kunye ne-Catanches zifana ne-tyrosine kunye ne-DOPA, iiarhente ezimhlophe zihlala zihleliwe okanye ezinokhuphiswano lweTyrosinase.

(3) Inqanaba lokugqibela le-melanin synthesis

① ● thintela ukudluliselwa kwengqondo; Izinto ezinomxholo we-serrieseaser profeeting, njenge-RWJ-50353, uphelela ngokupheleleyo i-UBV ePidermal Pigmation; I-soybean trypsin inhibitor inesiphumo esibonakalayo esibonakalayo kodwa ayinampembelelo kwityhefu yeeseli ze-pigment; I-Niacinamide, inokuthintela ukuhanjiswa kwamadlelanenocyte phakathi kwe-melanocytes kunye ne-keratiocyte; ② I-Metanin Ukusasazeka kunye neMetabolism, i-α-hydroxy acid, free grety acid, i-retinoic acid, ukukhuthaza ii-keratinos zeselfowuni zokususwa.

Kufanelekile ukuba uqaphele ukuba uphando kunye nokusetyenziswa kwezinto ezimhlophe ngokusekwe kule metanin yemetanin yemetanin ayifanelekanga ukubanjwa kunye nonyango lwe-sele. Ukusukela indlela yendlela ye-seleile plaque inxulumene nokwenziwa kwe-lipofuscin, izinto ezisebenzayo ze-antioxid ezisebenzayo zisetyenziselwa ukulibazisa kunye nokubuyela kwi-seeces.
