L-Ascorbic Acid 2-Glucoside
I-AA-2G (i-Ascorbic Acid 2-Glucoside) luhlobo lwe-vitamin-C yendalo, equkethe ukubunjwa okuzinzile kwe-glucose.Icandelo lenza ukuba ivithamin-C yenziwe izithambiso ngokufanelekileyo nangempumelelo, equlethe i-AA-2G Cream kunye ne-emulsion yolusu, nge-enzyme eluswini kunye nesenzo se-enzyme ye-alpha glycosidase, amacandelo aluncedo kwiivithamini-C ze-AA-2G inokuthunyelwa ngaphandle. kancinci.
I-AA2G yaphuhliselwa izithambiso zamayeza eJapan ngaphambili, ukungcungcuthekisa umbala, ukunciphisa amabala obudala kunye nemvula ye-pigment.Uphononongo olongezelelweyo lubonisa ukuba ineminye imisebenzi, ngoku kwihlabathi jikelele sebenzisa i-AA-2G, ayisetyenziselwa ukwenza mhlophe kuphela, kodwa inokuqaqambisa ulusu olumnyama, ukulwa nokuguga, ukukhusela ulusu kwiimveliso zelanga.

Imisebenzi kunye ne-Advanteji:
1.Uzinzo oluphezulu
I-Glucose kunye ne-C2 hydroxy ye-vitamin-C edityaniswe kwi-AA-2G, i-C2 hydroxyl yindawo yendalo ye-vitamin C yemisebenzi, kodwa kunye ne-vitamin C indawo yokuncipha.IGlucose ikhusela ivithamin C ikhusela ubushushu obuphezulu, i-pH, ii-ion zetsimbi kunye nokunye ukuqhekeka koomatshini ukuze kusebenze.
Umsebenzi we-2.Vitamin C uhlala uhleli
Xa iimveliso eziqulethe i-AA-2G yesikhumba, umsebenzi we-glycosidase ngokuthe ngcembe ukhulula i-vitamin C, ukwenza izithako ezincedo ze-vitamin C zinokugcina ixesha elide.
3. Khanyisa ulusu
I-AA-2G kunye ne-vitamin C ngumsebenzi osisiseko ofanayo, ngokusebenzisa i-melanin inhibiting cell cell ukukhusela i-pigmentation yesikhumba, ukunciphisa umxholo we-melanin okhoyo, kunye nokunciphisa i-pigmentation yesikhumba.
4. Ifomula elula
Xa kuthelekiswa nevithamin C yendalo, i-AA-2G yokunyibilika ngcono, izinzile kwiindawo ezininzi zexabiso le-pH, ngakumbi kwixabiso le-pH 5-7 kokusingqongileyo, kodwa nakwimveliso yokhathalelo lwesikhumba kwindawo eqhelekileyo.Xa kuthelekiswa nolunye uhlobo lwe-vitamin C, ifomula ye-AA-2G ilula kakhulu.
5. Ulusu olusempilweni
I-AA-2G ikhupha i-vitamin C ngokucothayo, inokudlula kwi-fibroblasts yesikhumba somntu ikhuthaza i-collagen synthesis, kunye nokwandisa ukuguquguquka kwesikhumba, i-AA-2G yenza ukuba ezi mpawu zihlale ixesha elide.I-fibroblasts yesikhumba somntu yafakwa kwiimeko zokubhekisela, i-vitamin (AsA; 0.25mM) okanye i-AA2G (0.25mM) malunga neentsuku ze-1-5, i-collagen synthesis kunye ne-protein synthesis ratio epheleleyo inokumiselwa, ebonisa i-AA2G Inokukhuthaza i-collagen synthesis, i-AA2G I-Excitation effect ezinzileyo iintsuku ezi-5.
6. Isikhuseli elangeni
Ulusu oluvezwe ngokuthe ngqo elangeni luya kuchaphazeleka yimitha ye-ozone, lo ngunobangela wokwenzakala kwesikhumba kunye nokubomvu, Ukubola okucothayo kwe-vitamin C ye-AA2G, kunomsebenzi wokuhlanjululwa kwemitha, kwaye ngaloo ndlela kuncitshiswe ukudumba kwesikhumba kunye noburhabaxa.
Ivithamin C
Kule mihla Iintlobo ngeentlobo zevithamin C eziphuma kwizinto zokuthambisa zisetyenziswa ngaphandle.I-vitamin C ecocekileyo, i-ascorbic acid okanye ebizwa ngokuba yi-L-ascorbic acid (i-ascorbic acid) inefuthe elithe ngqo.Ngokwahlukileyo kwezinye izinto ezahlukeneyo, akufuneki kuqala ukuba iguqulwe ibe yifom esebenzayo.Uphononongo lubonisa ukuba i-vitamin C isekela i-collagen synthesis kwaye ilwa nama-radicals amahhala.Ikwasebenza ngokuchasene namabala kunye namabala obudala ngokuthintela i-tyrosinase.Nangona kunjalo, i-ascorbic acid ayinakucutshungulwa kwikhilimu ngenxa yokuba isithako esisebenzayo sithinteka kakhulu kwi-oxidation kwaye sibola ngokukhawuleza.Ngoko ke, ukulungiselela njenge-lyophilisate okanye ukulawulwa njengomgubo kuyafaneleka.
Kwimeko ye-serum equkethe i-ascorbic acid, ukubunjwa kufuneka kube nexabiso elingqongqo le-pH ye-acidic ukuze kuqinisekiswe ukungena ngokufanelekileyo kwesikhumba.Ulawulo kufuneka lube yi-dispenser engangeni moya.Izinto eziphuma kwi-Vitamin C ezingasebenzi kakuhle ulusu okanye ezinyamezelekayo kwaye ezihlala zizinzile nakwiziseko zekhrimu zilungele kakhulu ulusu olubuthathaka okanye indawo yamehlo amancinci.
Kuyaziwa ukuba ukuxinana okuphezulu kwesithako esisebenzayo akuthethi isiphumo sokhathalelo olungcono.Ukukhethwa ngokucokisekileyo kuphela kunye nokuqulunqwa okulungiselelwe kwisithako esisebenzayo kuqinisekisa ukuba i-bioavailability efanelekileyo, ukunyamezela kakuhle kwesikhumba, ukuzinza okuphezulu, kunye nokusebenza kakuhle kwemveliso.
