I-L-Ascorbic Acid 2-Glucoside
I-AA-2G (Ascorbic Acid 2-Glucoside) iwuhlobo lwevithamini C yemvelo, equkethe ukwakheka okuzinzile kweglucose.Ingxenye yenza i-vitamin-C yenziwe izimonyo kalula nangempumelelo, equkethe i-AA-2G Cream kanye ne-emulsion yesikhumba, ngokusebenzisa i-enzyme esikhumbeni kanye nesenzo se-enzyme ye-alpha glycosidase, izingxenye ezizuzisayo kumavithamini-C we-AA-2G zingathunyelwa ngaphandle. kancane.
I-AA2G yakhelwe izimonyo zemithi e-Japan ngaphambilini, ukuze kuncishiswe umbala, kuncishiswe amachashaza eminyaka yobudala kanye nemvula yama-freckles pigment.Ucwaningo olwengeziwe lubonisa ukuthi futhi ineminye imisebenzi, manje emhlabeni wonke isebenzisa i-AA-2G, engasetshenziselwa ukwenza mhlophe kuphela, kodwa futhi ingakhanyisa isikhumba esimnyama, inqande ukuguga, ivikele isikhumba emikhiqizweni yelanga.

Imisebenzi kanye nenzuzo:
1.Ukuzinza okuphezulu
I-Glucose ne-C2 hydroxy ka-vitamin-C exhunywe ku-AA-2G , i-C2 hydroxyl izindawo zemvelo zokusebenza kukavithamini C, kodwa futhi i-vitamin C indawo yokuncipha.IGlucose ivikela uvithamini C gwema izinga lokushisa eliphezulu, i-pH, ama-ion ensimbi nokunye ukuqhekeka kwemishini ukuze kusebenze.
Umsebenzi we-2.Vitamin C uhlala njalo
Lapho imikhiqizo equkethe i-AA-2G yesikhumba, umsebenzi we-glycosidase ukhulula kancane kancane uvithamini C, ukwenza izithako ezizuzisayo zikavithamini C zingagcina isikhathi eside.
3. Khanyisa isikhumba
I-AA-2G kanye ne-vitamin C kuwumsebenzi ofanayo oyisisekelo, ngokuhlanganiswa kwe-melanin evimbela amangqamuzana e-melanin ukuvimbela ukugqama kwesikhumba, ukunciphisa okuqukethwe kwe-melanin okukhona, nokunciphisa isikhumba sombala.
4. Ifomula elula
Uma kuqhathaniswa novithamini C wemvelo, i-AA-2G encibilika kangcono, Iqinile uma kuqhathaniswa ezindaweni eziningi zenani le-pH , ikakhulukazi enanini le-pH elingu-5 - 7 endaweni, kodwa nasekuhlanganiseni komkhiqizo wokunakekelwa kwesikhumba endaweni evamile.Uma kuqhathaniswa namanye amafomula kavithamini C, ifomula ye-AA-2G ilula kakhulu.
5. Isikhumba esinempilo
I-AA-2G ikhulula uvithamini C kancane, ingadlula esikhumbeni somuntu i-fibroblasts ikhuthaze ukuhlanganiswa kwe-collagen, futhi ikhulise ukuguquguquka kwesikhumba, i-AA-2G yenza lezi zici ziqine. noma i-AA2G (0.25mM) cishe ezinsukwini ezingu-1-5, ukuhlanganiswa kwe-collagen kanye nenani eliphelele le-protein synthesis linganqunywa, okubonisa i-AA2G Ingakhuthaza ukuhlanganiswa kwe-collagen, umphumela we-AA2G Excitation uzinzile izinsuku ezi-5 eziphelele.
6. Ukuvikela ilanga
Isikhumba esivezwe ngokuqondile elangeni sizothinteka emisebeni ye-ozone, lokhu kuyimbangela yokulimala kwesikhumba nokubomvu, Ukubola kancane kwe-vitamin C ye-AA2G, kunomsebenzi wokuhlanzwa kwemisebe, futhi ngaleyo ndlela kunciphise ukuvuvukala kwesikhumba nokuba rough.
Ivithamini C
Namuhla Okuphuma ku-vitamin C okuhlukahlukene kusetshenziselwa izimonyo ukuze kusetshenziswe ngaphandle .I-vitamin C ehlanzekile, i-ascorbic acid noma ebizwa nangokuthi i-L-ascorbic acid (i-ascorbic acid) inomphumela oqondile kakhulu.Ngokuphambene nokunye okuhlukile, akudingeki ukuthi kuqala iguqulwe ibe ifomu elisebenzayo.Ucwaningo lubonisa ukuthi i-vitamin C isekela ukuhlanganiswa kwe-collagen futhi ilwa nama-radicals mahhala.Iphinde isebenze ngokumelene nama-acne namachashazi eminyaka ngokuvimbela i-tyrosinase.Kodwa-ke, i-ascorbic acid ayikwazi ukucutshungulwa ibe ukhilimu ngoba isithako esisebenzayo sithinteka kakhulu ku-oxidation futhi sibola ngokushesha.Ngakho-ke, ukulungiselela njenge-lyophilisate noma ukuphathwa njengempushana kufanelekile.
Endabeni ye-serum equkethe i-ascorbic acid, ukwakheka kufanele kube ne-pH ene-acidic eqinile ukuze kuqinisekiswe ukungena okungcono kakhulu esikhumbeni.Ukuphatha kufanele kube i-dispenser engangenisi umoya.Okuphuma ku-Vitamin C okungasebenzi kahle esikhumbeni noma okubekezeleleka kakhulu futhi okuhlala kuzinzile ngisho nasezisekelweni zikakhilimu kulungele ikakhulukazi isikhumba esibucayi noma indawo yamehlo amancane.
Kwaziwa kahle ukuthi ukugxila okuphezulu kwesithako esisebenzayo akusho umphumela wokunakekela ongcono.Ukukhethwa okucophelela kuphela kanye nokwakheka okujwayelane nesithako esisebenzayo okuqinisekisa ukuthi i-bioavailability ephelele, ukubekezelelana okuhle kwesikhumba, ukuzinza okuphezulu, nokusebenza komkhiqizo okungcono kakhulu.
