Yimuphi umphumela wokuba mhlophe ophephile futhi osebenza kangcono, okuhlanganisai-arbutin,uvithamini C, noma i-niacinamide?

I-Arbutin

 α- Arbutin: α- I-Arbutin inokuphepha okuhle, umphumela omhlophe, nokuzinza;

 β- Arbutin: izinto zokusetshenziswa ezishibhile

I-Deoxyarbutin: ukuzinza okubi nokusetshenziswa okuncane;

Umgomo wokuba mhlophe: I-Arbutin ivimbela ikakhulukazi ukukhiqizwa kwe-melanin ngokuvimbela umsebenzi we-tyrosinase (i-enzyme ebalulekile ohlelweni lokukhiqizwa kwe-melanin), ngaleyo ndlela ifinyelele umphumela wokwenza isikhumba sibe mhlophe.

uvithamini C

I-Vitamin C inomlando omude wokusetshenziselwa ukwenza mhlophe, futhi yaziwa nangokuthi i-ascorbic acid ngenxa yekhono layo eliqinile lokulwa ne-antioxidant, eliholela ekungazinzini nasekubola kalula. Ngakho-ke manje okuphuma kulo kusetshenziswa kakhulu. Ukwengeza iqembu le-inert eqenjini lalo elisebenzayo kuyenza izinze. Ngokwesibonelo,i-ascorbic acid glucoside (AA2G), okuphuma kuvithamini C, manje seyengezwa emikhiqizweni emhlophe emakethe.

Umgomo wokuba mhlophe: Umphumela wokuba mhlophe kavithamini C ungenxa yekhono lawo eliqinile lokulwa ne-antioxidant. Inganciphisa into emaphakathi ye-dopamine quinone ekuhlanganiseni kwe-melanin ku-dopamine, ivimbe uchungechunge lwe-oxidation olukhiqizwa i-melanin, ngaleyo ndlela ivimbele ukwakheka kwe-melanin futhi ibe nomthelela wokuba mhlophe.

Imithelela nezimiso zesenzo ezingafinyelelwa yilezi ezilandelayo:

I-Whitening: Indlela yokusebenza ifinyelelwa ngokuvimbela ukuthuthwa kwama-melanosomes ukusuka ku-melanocyte kuya kuma-keratinocyte.

Ukulawula uwoyela kanye nokunciphisa izimbotshana: kungalawula ukukhishwa kwe-sebum namafutha, kushwabane izimbotshana zesikhumba, futhi kwenze ukuthungwa kwesikhumba kuntekenteke kakhudlwana.

Uma isikhumba sakho singenakho ukungezwani okukhethekile, ukuqhathaniswa kokuphepha kwalezi zithako ezintathu: i-niacinamide.
