I-Arbutin, izinto ezisebenzayo zokucwenga kwemvelo
incazelo2
Umsebenzi kanye nesicelo
1. Umthelela wokuba mhlophe: I-Alpha Arbutin ithathwa njengesithako esisebenza kakhulu esimhlophe. Ingavimbela ukusebenza kwe-tyrosinase, inciphise ukwakheka kanye nokufakwa kwe-melanin, futhi ikhanyise ngempumelelo izinkinga zombala wesikhumba njengamabala amnyama, amabala kanye namabala elanga. Ngesikhathi esifanayo, ikhipha ithoni yesikhumba futhi ikhanyise isikhumba esimnyama.
2. Vimbela ukukhiqizwa kwe-melanin: I-Alpha arbutin ingaphazamisa inqubo yokuhlanganiswa kwe-melanin, ivimbele umsebenzi we-oxidase we-tyrosine, futhi ivimbele ukwakheka kwe-melanin. Lokhu kuyenza ibe isithako esifanelekile sokunakekelwa kwesikhumba esivimba ukukhiqizwa ngokweqile kwe-melanin, kwehlise ubungozi be-hyperpigmentation kanye nokwakheka kwamabala.
3. Ukuphepha nokuzinza: Uma kuqhathaniswa nezinye izithako ezimhlophe, i-Alpha Arbutin inokuphepha nokuzinza okuphezulu. Ngeke ilahlekelwe umsebenzi wayo ngenxa yokukhanya noma i-oxidation, futhi ingagcina umphumela wayo wokuba mhlophe isikhathi eside. Ngaphezu kwalokho, i-alpha arbutin ibonisa ukucasuka okuphansi esikhumbeni futhi ifanele zonke izinhlobo zesikhumba.
4. I-moisturizing kanye ne-anti-oxidation: Ngaphezu komphumela wokuba mhlophe, i-alpha arbutin futhi inemiphumela yokuthambisa kanye ne-anti-oxidation. Ingakhuphula umswakama we-stratum corneum, ithuthukise ibhalansi yomswakama wesikhumba, futhi ikhulule ngokuphumelelayo ukoma nokuqina kwesikhumba. Ngesikhathi esifanayo, inciphisa ama-radicals mahhala, ivikela ekucindezelekeni kwe-oxidative, futhi ivikela isikhumba ekulimaleni kwemvelo.
