Mugadziri wechishamiso chekuchenesesa - phenethyl resorcinol

Murwendo rurefu rwekutsvaga ganda rakanaka, vanhu vakawanda vane runako - vanoda runako vari kugara vachiongorora zvakavanzika zvekuchenesa zvinobudirira uye zvakachengeteka. Mazuva ano, nyeredzi inopenya mumunda wekuchenesa - phenylethyl resorcinol, nekushanda kwayo kunoshamisa, iri kuvhura rwendo runoshamisa rwekuchenesa ganda kwatiri.
Melanin ndiye "Nemesis ane simba" we melanin. Melanin ndiye "mhosva" yekusviba kweganda uye kukura kwemavara, uye tyrosinase ndiyo "mutyairi wepachivande" akakosha mukugadzirwa kwe melanin. Phenylethylresorption ine chimiro chakasiyana chemamorekuru, chakafanana ne "munyengeri" akadzidziswa zvakanaka, anokwanisa kutevedzera zvakanyatsonaka substrate ye tyrosinase uye kubata neunyanzvi nzvimbo inoshanda ye enzyme, nokudaro achidzivirira zvinobudirira kushanda kwe tyrosinase. Nenzira iyi, nzira yekugadzira melanin inovharwa zvinobudirira, zvichibvisa mukana wekusviba kweganda. Data rekutsvagisa kwesainzi rakasimbisazve kugona kwakasimba kwe phenethyl resorcinol: mhedzisiro yayo yekudzivirira pa tyrosinase inopfuura zvakanyanya iyo yezvinhu zvechinyakare zvekucheneswa, iri ka22 ka kojic acid uye kanopfuura zana ka arbutin!
"Murindi weAntioxidant" weganda Muhupenyu hwezuva nezuva, ganda redu rinogara richisangana nezvinhu zvekunze zvakaita semwaranzi ye ultraviolet uye kusvibiswa kwezvakatipoteredza. Zvinhu izvi zvakaipa zvinogona kukonzera kugadzirwa kwakanyanya kwe free radicals, nokudaro zvichikurumidzisa kugadzirwa kwe melanin uye zvichikonzera matambudziko ekukwegura kweganda. Phenethyl resorcinol, se "murindi weAntioxidant" asingatyi, inogona kubvisa free radicals, inoderedza kukuvara kwemwaranzi ye ultraviolet paganda, uye inodzivirira hutano nerunako rweganda zvakakwana. Kana ukashandisa zvigadzirwa zvine phenethyl resorcinol nguva dzose, kugona kwe antioxidants kweganda rako kuchawedzera zvakanyanya, uye zviratidzo zvekukwegura zvakaita semitsetse midiki uye kudzika kweganda zvichadzikira zvishoma nezvishoma, zvichiita kuti ganda rako rirambe riri jaya nguva dzese.
Yakachengeteka uye yakapfava, "sarudzo ine musoro" kune ganda rinonzwa kuchena. Kune vazhinji vevatengi, kuchengetedzeka kwezvinhu zvinochenesa kunokosha zvikuru. Phenethyl resorquinone yakabatanidzwa mu "Catalogue of Used Cosmetic Raw Materials" muChina. Kana ikashandiswa mukati mehuwandu hwakatarwa hwehuwandu (kazhinji 0.2%-0.5%), yakachengeteka zvikuru. Zvidzidzo zvakawanda zvehunyanzvi zvakaratidza kuti phenethyl resorcinol haina kushatirwa zvakanyanya paganda, uye kunyangwe ganda rakapfava uye rinonzwa kuchena rinogona kuishandisa nerunyararo rwepfungwa. Ehe, kuti ive nechokwadi chekuti zvese hazvina njodzi, shamwari dzine ganda rinonzwa kuchena dzinokurudzirwa kuyedza chigadzirwa chine chinhu ichi panzvimbo yeganda pakutanga pavanochishandisa kekutanga.
Kusimbiswa kwesainzi kunoratidza mhedzisiro inoshamisa yekuchena kweganda. Mhedzisiro yekuyedza kwakasimba kwekiriniki pavakadzi vekuAsia inoshamisa: mushure memavhiki masere akateedzana ekushandisa mushonga wekuchena une 0.5% phenylethyl resorcinol, kusvika 91% yevanhu vakaongororwa vakaona kudzikira kukuru munzvimbo yemavanga epigmentation, uye kupenya kweganda kwakawedzera ne17.3%. Ruzivo urwu runoratidza zvizere kushanda kwakanaka kwephenylethyl resorcinol mumunda wekuchena kweganda uye mavanga ekupenya. Kunyangwe uchinetseka nemavanga ezuva kana melasma, kana uchida kuvandudza ganda risina kupenya uye risina kuenzana, phenylethyl resorcinol ichakubatsira zvikuru mukuzadzisa hope dzako dzekuchena kweganda. Munzira yekuchena kweganda, phenylethyl resorcinol pasina mubvunzo ndiye mudiwa wako akavimbika. Kusarudza zvigadzirwa zvine phenylethyl resorcinol zvinoreva kusarudza kuisa simba rine simba rekuvandudza ganda uye kuchena. Ngatishandei pamwe chete kuti tisiyane nekusviba, kugamuchira kupenya, uye kupenya nechivimbo!
