Muzvizoro, inogona kunyatso chena uye kubvisa mavanga paganda, uye zvishoma nezvishoma kupera uye kubvisa mafinya, chloasma, melanin, mburwa uye zera mavara paganda. Yakachengeteka zvakanyanya uye haina mhedzisiro yakadai sekushatirwa uye kusimudzira. Arbutin iri nyore hydrolyzed uye inofanira kushandiswa pa pH ye5-7. Kuti ugadzikane kuita, huwandu hwakakodzera hwema antioxidants senge sodium bisulfite uye vhitamini E inowanzo wedzerwa kuti iwane kuchena, kubvisa freckle, kunyorova, kupfava, kubvisa wrinkle, uye anti-inflammatory effects.

Nekudaro, hydroquinone ine mhedzisiro uye inoda matanho akawanda ekuzvidzivirira. Inofanira kushandiswa pasi pekutungamirirwa uye kuongororwa nachiremba. Kune akawanda mamorekuru eglucose muchimiro che arbutin pane hydroquinone.
Iine kushatirwa kwakaderera uye inogona kuwedzerwa zvakasununguka kune zvigadzirwa zvekuchengetedza ganda zvine muganho wepamusoro wepamusoro unosvika 7%.
Mamorekuru anoshanda e arbutin anogona kupinda mu basal layer yeganda kuitira kupenya kwakadzika, uye anogona kurapa chloasma, makwapa matema, makwapa ezuva, uye pigmentation inosara kubva kumishonga inodhaka.
Vese vane simba rekurapa mhedzisiro, asi kana iyo yekumisikidza yakadzikira, iyo durability yemhedzisiro inove isina simba, saka 5% yekumisikidza ndiyo yakachengeteka uye yakanyanya kunaka yekuisa kujekesa.
Iko kusanganiswa kwe5% inokurumidza kupfuura vhitamini C mukujekesa mavara, uye mhedzisiro yekuvhenekesa yakagadzikana uye haizokonzeri kutsamwa paganda.
Arbutin ichaderedzwa kuita hydroquinone mushure mekubatwa neganda. Izvi zvakonzera kuti vamwe vanhu vasave nechokwadi chekuchengetedzwa kweArbutin uye vanotenda kuti arbutin inogona kuramba ichigadzirwa.
Hydroquinone-yakafanana nemhedzisiro. Chirevo chinonyanyozivikanwa ndechekuti "zvigadzirwa zvekuchengetedza ganda zvine arbutin hazvigone kushandiswa mukati mezuva, zvikasadaro ganda harizocheneswa uye richasviba."
Kutaura zvazviri, hapana chikonzero chokunetseka. Miedzo yakaratidza kuti arbutin chete ine concentration inodarika 7% inogona kunzwa kuchiedza. Naizvozvo, 7% inzvimbo yakakosha yekuchengetedza. Pane mitemo yakajeka pamusoro pekuwedzera kwezvigadzirwa muzvigadzirwa zvekuchengetedza ganda. Iyo yakanyanya kusungirirwa muganhu ndeye 7%. Mukati meiyi renji yekuisa, arbutin haina kukwana kukonzera photosensitivity, saka haigone kushandiswa pasina chiedza chekudzivirira.
Kana yakanyura mukati meganda uye yakaora nechiedza, inoderedzwa kuita hydroquinone, ichigadzira chena maitiro. Kuwanda kwehydroquinone muzvigadzirwa zvekuchengetedza ganda arbutin kuri pasi pe20 ppm (kureva, zvikamu makumi maviri pamiriyoni). Pasi pemuganho wakaderera wakadaro, hydroquinone haizokonzerese mhedzisiro senge kusviba kweganda.
Kana iwe uchitya kushandisa zvigadzirwa zvekuchengetedza ganda mukati mezuva nekuda kwekuti zvine arbutin, saka haufanirwe kudaro, kunze kwekunge zvigadzirwa zvekuchengetedza ganda zvine arbutin zvinowedzerawo zvimwe zvinongedzo zvekuchengetedza ganda zvinoda kuchengetedzwa kubva kuchiedza.
Muchidimbu, iwe unofanirwa kusarudza zvigadzirwa zvekuchengetedza ganda kubva kumhando dzakavimbika, uye zvisinei kuti chii chaunoshandisa, shandisa zuva kudzivirira mukati mezuva.
