Vitamini C(VC) ndizomwe zimagwiritsidwa ntchito poyera zodzoladzola, koma pali mphekesera kuti kugwiritsa ntchito zodzoladzola zokhala ndi VC masana sikudzalephera kuyeretsa khungu, komanso kudzadetsa khungu; anthu ena ali ndi nkhawa kuti kugwiritsa ntchito mankhwala osamalira khungu omwe ali ndi VC ndi nicotinamide nthawi imodzi kungayambitse ziwengo. Kugwiritsa ntchito zodzoladzola za VC kwa nthawi yayitali kumapangitsa khungu kukhala lochepa kwambiri. M'malo mwake, izi ndizosamvetsetsana pazodzikongoletsera zomwe zili ndi VC.
Bodza 1: Kugwiritsa ntchito masana kumadetsa khungu lanu
VC, yomwe imadziwikanso kuti L-ascorbic acid, ndi antioxidant yachilengedwe yomwe ingagwiritsidwe ntchito pochiza ndi kuteteza khungu kupsa ndi dzuwa. Mu zodzoladzola, VC imatha kuchedwetsa kaphatikizidwe ka melanin monga dopaquinone polumikizana ndi ayoni amkuwa pamalo okhazikika a tyrosinase, potero kusokoneza kupanga melanin ndikukwaniritsa kuyera ndikuchotsa mabala.
Mapangidwe a melanin amagwirizana ndi makutidwe ndi okosijeni. Monga antioxidant wamba,VCimatha kuletsa makutidwe ndi okosijeni, ipangitse kuyanika kwina, imathandizira kukonza khungu ndikusinthanso mphamvu, kuchedwetsa kukalamba, komanso kuchepetsa kuwonongeka kwa ultraviolet pakhungu. VC ndi yosakhazikika ndipo imakhala ndi okosijeni mosavuta mumlengalenga ndipo imataya ntchito yake ya antioxidant. Kuwala kwa ultraviolet kudzafulumizitsa ndondomeko ya okosijeni. Choncho, tikulimbikitsidwa kugwiritsa ntchitoZodzoladzola zomwe zili ndi VCusiku kapena kutali ndi kuwala. Ngakhale kugwiritsa ntchito zodzoladzola zokhala ndi VC masana sikungakwaniritse zotsatira zabwino, sikungapangitse khungu kukhala mdima. Ngati mumagwiritsa ntchito zosamalira khungu zomwe zili ndi VC masana, muyenera kudziteteza ku dzuwa, monga kuvala zovala za manja aatali, chipewa, ndi parasol. Magwero opangira kuwala monga nyali za incandescent, nyali za fulorosenti, ndi nyali za LED, mosiyana ndi kuwala kwa ultraviolet, sizimakhudza VC, kotero palibe chifukwa chodera nkhawa za kuwala komwe kumatulutsa zowonetsera mafoni zomwe zimakhudza mphamvu ya zodzoladzola zomwe zili ndi VC.
Bodza lachiwiri: Kugwiritsa ntchito nthawi yayitali kumapangitsa khungu kukhala lochepa thupi
Zomwe timatchula nthawi zambiri“khungu kupatulira”kwenikweni ndi kupatulira kwa stratum corneum. Chifukwa chofunikira cha kupatulira kwa stratum corneum ndikuti ma cell omwe ali mu basal wosanjikiza amawonongeka ndipo sangathe kugawanitsa ndikuberekana bwino, ndipo kagayidwe kachakudya koyambirira kumawonongeka.
Ngakhale VC ndi acidic, VC zili mu zodzoladzola sikokwanira kuvulaza khungu. VC sichipangitsa kuti stratum corneum ikhale yowonda, koma anthu omwe ali ndi stratum corneum yowonda amakhala ndi khungu lovuta kwambiri. Chifukwa chake, mukamagwiritsa ntchito zinthu zoyera zokhala ndi VC, muyenera kuyesa kaye kumadera monga kumbuyo kwa makutu kuti muwone ngati pali ziwengo.
Zodzoladzolaziyenera kugwiritsidwa ntchito moyenera. Mukawagwiritsa ntchito mopitilira muyeso pofunafuna kuyera, nthawi zambiri mumataya zambiri kuposa zomwe mumapeza. Pankhani ya VC, zofuna za thupi la munthu ndi kuyamwa kwa VC ndizochepa. VC yomwe imaposa magawo ofunikira a thupi la munthu sikuti imangotengeka, komanso imatha kuyambitsa kutsekula m'mimba komanso kukhudza ntchito ya coagulation. Choncho, zodzoladzola zomwe zili ndi VC siziyenera kugwiritsidwa ntchito mopitirira muyeso.
