Isithako Esinamandla Sokumhlophe Kwesikhumba

I-Kojic acid iyinto yemvelo edumile embonini yokunakekelwa kwesikhumba ngenxa yezakhiwo zayo ezinhle kakhulu ezikhanyisa isikhumba. I-Kojic acid itholakala ezinhlobonhlobo zesikhunta, ikakhulukazi i-Aspergillus oryzae, futhi yaziwa ngekhono layo lokuvimbela ukukhiqizwa kwe-melanin, i-pigment ebangela umbala wesikhumba. Lokhu kuyenza ibe isithako esidumile emikhiqizweni eyenzelwe ukubhekana ne-hyperpigmentation, amabala amnyama, nethoni yesikhumba engalingani.

Ukusetshenziswa kwe-kojic acid emikhiqizweni yokunakekelwa kwesikhumba kungalandelelwa emuva ekusetshenzisweni kwendabuko e-Japan. Ekuqaleni kwatholakala njengomkhiqizo wenqubo yokuvutshelwa ngesikhathi sokukhiqizwa kwe-sake, iwayini lerayisi laseJapane. Ngokuhamba kwesikhathi, izici zayo ezikhanyisa isikhumba zaqashelwa futhi zafakwa emafomula ahlukahlukene okunakekela isikhumba.

Enye yezinzuzo eziyinhloko ze-kojic acid yikhono layo lokukhanyisa ngokuphumelelayo amabala amnyama kanye ne-hyperpigmentation ngaphandle kokubangela ukucasuka kwesikhumba. Lokhu kukwenza kube ukukhetha okuphezulu kubantu abanesikhumba esibucayi okungenzeka bangakwazi ukubekezelela izithako ezikhanyisa isikhumba ezinolaka. Ukwengeza, i-kojic acid yaziwa ngezakhiwo zayo ze-antioxidant, ezisiza ukuvikela isikhumba emonakalweni wemvelo nokuguga ngaphambi kwesikhathi.

Uma yengezwe emikhiqizweni yokunakekelwa kwesikhumba, i-kojic acid isebenza ngokuvimbela umsebenzi we-tyrosinase, i-enzyme ehilelekile ekukhiqizeni i-melanin. Ngokwenza kanjalo, kusiza ukunciphisa ukukhiqizwa ngokweqile kwe-melanin, okuholela esikhumbeni esilinganayo futhi kunciphise ukubukeka kwamabala amnyama. Le ndlela yokusebenza yenza i-kojic acid ibe isithako esisebenzayo ekubhekaneni nezinhlobo ezahlukene ze-hyperpigmentation, okuhlanganisa i-melasma, amabala elanga, kanye ne-post-inflammatory hyperpigmentation.

I-Kojic acid ivame ukutholakala ezinhlobonhlobo zemikhiqizo yokunakekelwa kwesikhumba, okuhlanganisa ama-serum, okhilimu nezihlanzi. Uma usebenzisa imikhiqizo equkethe i-kojic acid, kubalulekile ukulandela imihlahlandlela yokusetshenziswa enconyiwe ukuze ugweme imiphumela engemihle engaba khona. Nakuba i-kojic acid ngokuvamile ibhekwa njengephephile ukusetshenziswa kwezihloko, abanye abantu bangase babe nokucasuka okuncane noma ukungezwani komzimba. Kunconywa ukwenza ukuhlolwa kwe-patch ukuhlola ukuzwela kwesikhumba ngaphambi kokusebenzisa imikhiqizo equkethe i-kojic acid.

Ngaphezu kwezinzuzo zayo ezikhanyisa isikhumba, i-kojic acid yaziwa futhi ngamandla ayo okubhekana nezinye izinkinga zesikhumba. Icutshungulwe ngemiphumela yayo yokulwa nokuvuvukala kanye ne-antibacterial, okuyenza ibe isithako esisebenza ngezindlela eziningi kulabo abanesikhumba esinezinduna noma esizwelayo. Ngokunciphisa ukuvuvukala nokuvimbela ukukhula kwamagciwane abangela induna, i-kojic acid ingasiza isikhumba sibukeke sicacile futhi sinempilo.

Kubalulekile ukuqaphela ukuthi nakuba i-kojic acid ingaletha imiphumela emangazayo ekubhekaneni ne-hyperpigmentation, ayisona isisombululo esilingana konke. Abantu abane-hyperpigmentation enzima kakhulu noma izimo zesikhumba ezingaphansi kufanele babonane nodokotela wesikhumba ukuze banqume ukwelashwa okufanele kakhulu. Kwezinye izimo, inhlanganisela yemikhiqizo yokunakekelwa kwesikhumba, ukwelashwa kochwepheshe, nezinguquko zendlela yokuphila zingadingeka ukuze kuzuzwe imiphumela emihle.

Uma uhlanganisa i-kojic acid ohlelweni lwakho lokunakekela isikhumba, ukuvikela ilanga kufanele kube yinto ehamba phambili. Uma usebenzisa izithako ezimhlophe njenge-kojic acid, isikhumba siba lula ekulimaleni kwe-UV. Ngakho-ke, ukusebenzisa i-spectrum ebanzi yokuvikela ilanga ene-SPF ephezulu kubalulekile ukuze kuvinjwe ukunwebeka kombala nokuvikela isikhumba emonakalweni welanga.

Sekukonke, i-kojic acid iyisithako esinamandla esibhekana ngokuphumelelayo ne-hyperpigmentation futhi ikhuthaze ithoni yesikhumba esilinganayo. Imvelaphi yayo yemvelo kanye nezakhiwo ezikhanyayo kodwa ezinamandla ezikhanyisa isikhumba ziyenza ibe yinto ethandwayo embonini yokunakekelwa kwesikhumba. Kungakhathaliseki ukuthi isetshenziswa njengengxenye yokwelapha okuhlosiwe kwamachashazi amnyama noma ifakwe ohlelweni olubanzi lokunakekela isikhumba, i-kojic acid inikeza isixazululo esithembisayo kubantu abafuna ukuba nebala elikhanyayo, elikhazimulayo. Njenganoma yisiphi isithako sokunakekelwa kwesikhumba, kunconywa ukuthi uxhumane nochwepheshe bokunakekelwa kwesikhumba ukuze uthole ukuthi yini esebenza kangcono ekukhathazeni kwesikhumba ngasinye kanye nezinjongo.
