Uwaremye igitangaza cyo kweza - phenethyl resorcinol

Mu rugendo rurerure rwo gushaka uruhu rwiza, abantu benshi bakunda ubwiza n'urukundo bahora bashakisha amabanga yo kwera neza kandi mu mutekano. Muri iki gihe, inyenyeri irabagirana mu rwego rwo kwera - phenylethyl resorcinol, ifite ubushobozi budasanzwe, irimo kudufungurira urugendo rutangaje rwo kwera uruhu.
Melanin ni "Nemesis ikomeye" ya melanin. Melanin ni "itera" kwijima no gukura kw'utudomo, naho tyrosinase ni "ikintu cy'ingenzi gitera kwijima" mu gikorwa cyo gukora melanin. Phenylethylresorption ifite imiterere yihariye ya molekile, nk'"umunyembaraga" watojwe neza, ushobora kwigana neza substrate ya tyrosinase no gufata mu buryo bunoze aho enzyme ikora, bityo ikabuza neza imikorere ya tyrosinase. Muri ubu buryo, inzira yo gukora melanin irafungwa neza, bikuraho by'ukuri amahirwe yo kwijima k'uruhu. Amakuru y'ubushakashatsi bwa siyansi yemeje ubushobozi bukomeye bwa phenethyl resorcinol: ingaruka zayo zo gukumira tyrosinase zirenze kure iz'ibintu gakondo byo kwera, zikaba inshuro 22 z'aside kojic n'inshuro zirenga 100 z'aside arbutin!
"Umurinzi wa antioxydant" w'uruhu Mu buzima bwa buri munsi, uruhu rwacu ruhora ruhura n'ibintu byo hanze nk'imirasire ya ultraviolet n'umwanda w'ibidukikije. Ibi bintu bibi bishobora gutera ikorwa ryinshi rya radicals free, bityo bikihutisha ikorwa rya melanin bigatera ibibazo byo gusaza k'uruhu. Phenethyl resorcinol, nk'umurinzi wa "antioxydant" utagira ubwoba, ishobora gukuraho radicals free, ikagabanya neza kwangirika kw'imirasire ya ultraviolet ku ruhu, kandi ikarinda ubuzima n'ubwiza bw'uruhu burundu. Iyo ukoresheje ibikoresho birimo phenethyl resorcinol igihe kirekire, ubushobozi bwa antioxydant bw'uruhu rwawe buzarushaho kwiyongera, kandi ibimenyetso byo gusaza nk'imirongo mito no kugabanuka bizagenda bigabanuka buhoro buhoro, bigatuma uruhu rwawe ruhora rukiri rushya.
Ifite umutekano kandi yoroshye, ni "amahitamo meza" ku ruhu rworoshye. Ku bakoresha benshi, umutekano w'ibintu byo kuzunguza ni ingenzi cyane. Phenethyl resorquinone yashyizwe mu "Catalogue of Used Cosmetic Raw Materials" mu Bushinwa. Iyo ikoreshejwe mu rugero rwagenwe (ubusanzwe 0.2%-0.5%), ni umutekano cyane. Ubushakashatsi bwinshi bw'inzobere bwagaragaje ko phenethyl resorcinol itera ububabare buke ku ruhu, kandi n'uruhu rworoshye kandi rworoshye rushobora kuyikoresha ituze ryo mu mutima. Birumvikana ko kugira ngo byose bigenzurwe neza, inshuti zifite uruhu rworoshye zigirwa inama yo kubanza gupima iki gicuruzwa kirimo iki kintu ku gace k'uruhu gaherereyemo mugihe zigikoresha bwa mbere.
Igenzura rya siyansi rigaragaza ingaruka zikomeye zo kwera uruhu. Ibisubizo by'igerageza rikomeye ryakorewe ku bagore bo muri Aziya biratangaje: nyuma y'ibyumweru 8 bikurikiranye hakoreshejwe ifu igabanya uruhu irimo 0.5% ya phenylethyl resorcinol, kugeza kuri 91% by'abakoreweho ubushakashatsi bagabanutse cyane mu gace k'ibice by'ibara, kandi urumuri rw'uruhu rwiyongereyeho 17.3%. Aya makuru agaragaza neza akamaro ka phenylethyl resorcinol mu bijyanye no kwera no gukurura uruhu. Waba ubangamiwe n'ibice by'izuba cyangwa melasma, cyangwa wifuza kunoza uruhu rudasobanutse kandi rutangana, phenylethyl resorcinol izagufasha cyane mu kugera ku nzozi zawe zo kwera uruhu. Mu nzira yo kwera, phenylethyl resorcinol nta gushidikanya ko ari we mufatanyabikorwa wawe wizeye cyane. Guhitamo ibikoresho birimo phenylethyl resorcinol bivuze guhitamo gutera imbaraga zikomeye zo kuvugurura uruhu no kuruhindura uruhu. Dufatanye gusezera ku bice by'ibara, twemere urumuri, kandi turabagirane twizeye!
