Ohambweni olude lokufuna isikhumba esikhanyayo, abantu abaningi abanothando nobuhle bahlala behlola izimfihlo zokwenza mhlophe eziphumelelayo neziphephile. Namuhla, inkanyezi ekhanyayo ensimini yokwenza mhlophe - i-phenylethyl resorcinol, esebenza kahle kakhulu, isivulela uhambo olumangalisayo lokukhanyisa isikhumba.
I-Melanin “iyi-Nemesis enamandla” ye-melanin. I-Melanin “iyimbangela” yokwenza isikhumba sibe mnyama futhi sikhule amabala, kanti i-tyrosinase “iyimbangela ebalulekile” enqubweni yokwenziwa kwe-melanin. I-Phenylethylresorption inesakhiwo sama-molecule esiyingqayizivele, njenge-“impostor” eqeqeshwe kahle, ekwazi ukulingisa ngokunembile i-substrate ye-tyrosinase futhi ibambe ngobuhlakani indawo esebenzayo ye-enzyme, ngaleyo ndlela ivimbele ngempumelelo umsebenzi we-tyrosinase. Ngale ndlela, indlela yokwenziwa kwe-melanin ivinjiwe ngempumelelo, okususa ngokuphelele amathuba okuba isikhumba sibe mnyama. Imininingwane yocwaningo lwesayensi iye yaqinisekisa ngokwengeziwe amakhono anamandla e-phenethyl resorcinol: umphumela wayo wokuvimbela ku-tyrosinase udlula kakhulu owezithako zokwenza mhlophe zendabuko, ophindwe izikhathi ezingu-22 kune-kojic acid kanye nezikhathi ezingaphezu kwe-100 kune-arbutin!
"Umqaphi we-antioxidant" wesikhumba Empilweni yansuku zonke, isikhumba sethu sihlala sibhekene nezinto zangaphandle ezifana nemisebe ye-ultraviolet kanye nokungcola kwemvelo. Lezi zinto ezimbi zingabangela ukukhiqizwa ngokweqile kwama-free radicals, ngaleyo ndlela kusheshiswe ukukhiqizwa kwe-melanin futhi kubangele izinkinga zokuguga kwesikhumba. I-Phenethyl resorcinol, njenge-"antioxidant guardian" enesibindi, ingasusa ngenkuthalo ama-free radicals, inciphise ngempumelelo umonakalo wemisebe ye-ultraviolet esikhumbeni, futhi ivikele ngokuphelele impilo nobuhle besikhumba. Uma usebenzisa njalo imikhiqizo equkethe i-phenethyl resorcinol isikhathi eside, amandla esikhumba sakho okulwa ne-antioxidant azothuthukiswa kakhulu, futhi izimpawu zokuguga njengemigqa emincane nokugoba kuzoncipha kancane kancane, kugcine isikhumba sakho sisesisha ngaso sonke isikhathi.
Iphephile futhi imnene, "ukukhetha okucatshangelwe kahle" kwesikhumba esizwelayo. Kwabaningi babathengi, ukuphepha kwezithako zokwenza mhlophe kubaluleke kakhulu. I-Phenethyl resorquinone ifakiwe ku-"Catalogue of Used Cosmetic Raw Materials" eShayina. Uma isetshenziswa ngaphakathi kobubanzi obunqunyiwe bokuhlushwa (ngokuvamile u-0.2%-0.5%), iphephile kakhulu. Izifundo eziningi zobungcweti zikhombisile ukuthi i-phenethyl resorcinol inobuhlungu obuncane esikhumbeni, futhi ngisho nesikhumba esibucayi kakhulu nesizwelayo singayisebenzisa ngokuthula kwengqondo. Vele, ukuqinisekisa ukuthi konke kuphephile, abangane abanesikhumba esizwelayo bayelulekwa ukuthi bahlole umkhiqizo oqukethe lesi sithako endaweni yesikhumba kuqala lapho beyisebenzisa okokuqala.
Ukuqinisekiswa kwesayensi kukhombisa umphumela omangalisayo wokwenza mhlophe. Imiphumela yokuhlolwa okuqinile kwezokwelapha kwabesifazane base-Asia iyamangalisa: ngemva kwamasonto ayi-8 alandelanayo okusebenzisa i-whitening essence equkethe i-0.5% phenylethyl resorcinol, efinyelela ku-91% wabantu abathintekayo bathole ukwehla okukhulu endaweni yamabala ombala, futhi ukukhanya kwesikhumba kwanda ngo-17.3%. Lolu lwazi lubonisa ngokugcwele ukusebenza kahle kwe-phenylethyl resorcinol emkhakheni wokwenza mhlophe nokukhanyisa amabala. Kungakhathaliseki ukuthi ukhathazwa amabala elanga noma i-melasma, noma ulangazelela ukuthuthukisa ithoni yesikhumba engacacile nengalingani, i-phenylethyl resorcinol izoba umsizi onamandla ekufezeni iphupho lakho lokwenza mhlophe isikhumba. Endleleni yokwenza mhlophe, i-phenylethyl resorcinol ngokungangabazeki ingumlingani wakho othembekile kakhulu. Ukukhetha imikhiqizo equkethe i-phenylethyl resorcinol kusho ukukhetha ukufaka amandla anamandla okuvuselela nokulungisa isikhumba. Masibambisane ukuze sivalelise ukuba mhlophe, samukele ukukhanya, futhi sikhanye ngokuzethemba!
