Whitening Cosmetics uyePigmentMetabolism
Melanin anabolism yakakamurwa kuva nguva dzakasiyana. Masayendisiti anotenda kuti zvinogoneka kudzidza chena maajenti uye kushanda kune dzakasiyana metabolic nguva.
(1) Nhanho yekutanga ye melanin synthesis
① Kukanganisa kunyorwa uye/kana glycosylation ye tyrosinase; ② Inhibit regulators mukugadzirwa kwe tyrosinase; ③ Post-kunyorwa kudzora kwetyrosinase.
(2) Melanin synthesis nguva
Seyakakosha enzyme uye chiyero-inomisa enzyme ye melanin synthesis, tyrosinase inhibitors ndiyo huru yekutsvagisa uye kutungamira kutungamira parizvino. Sezvo akawanda ekuchena maajenti akadai se phenol uye catechol derivatives ane chimiro chakafanana netyrosine uye dopa, maajenti ekuchena akaongororwa anowanzo kurondedzerwa seasiri emakwikwi kana emakwikwi inhibitors etyrosinase.
(3) Nguva yekupedzisira ye melanin synthesis
① Inhibits melanosome kutamiswa; zvinhu zvine serine protease inhibitory effect, senge rwj-50353, inodzivirira zvachose UBV-induced epidermal pigmentation; soyabean trypsin inhibitor ine kuchena kuri pachena mhedzisiro asi haina mhedzisiro pahupfu hwema cell pigment; Niacinamide, inogona kutadzisa kutapurirana kwe melanocyte pakati pe melanocytes uye keratinocytes; ② Melanin dispersion uye metabolism, α-hydroxy acid, yemahara fatty acid uye retinoic acid, inokurudzira sero kuvandudzwa uye kukurudzira melaninized keratinocytes yekubvisa.
Zvakakosha kucherechedza kuti kutsvagisa nekushandiswa kwezvinochenesa zvinhu zvichibva pane iri pamusoro pe melanin metabolism hazvina kukodzera kudzivirira uye kurapwa kwesenile plaques. Sezvo nzira yekugadzira senile plaque yakabatana nekugadzirwa kwe lipofuscin, antioxidative active substances inowanzoshandiswa kunonoka uye kudzosera senile plaques.
