Mu zodzoladzola, akhoza bwino whiten ndi kuchotsa mawanga pa khungu, ndipo pang`onopang`ono kuzimiririka ndi kuchotsa mawanga, chloasma, melanin, ziphuphu zakumaso ndi zaka mawanga pa khungu. Ndizotetezeka kwambiri ndipo zilibe zotsatira zoyipa monga kukwiyitsa komanso kulimbikitsa. Arbutin imapangidwa mosavuta ndi hydrolyzed ndipo iyenera kugwiritsidwa ntchito pa pH ya 5-7. Kuti akhazikitse magwiridwe antchito, kuchuluka koyenera kwa ma antioxidants monga sodium bisulfite ndi vitamini E nthawi zambiri amawonjezeredwa kuti akwaniritse bwino kuyera, kuchotsa makwinya, kunyowa, kufewa, kuchotsa makwinya, ndi zotsatira zotsutsana ndi zotupa.

Komabe, hydroquinone ili ndi zotsatira zoyipa ndipo imafuna kusamala kwambiri. Iyenera kugwiritsidwa ntchito motsogozedwa ndi kuyang'aniridwa ndi dokotala. Pali mamolekyu ambiri a shuga m'mapangidwe a arbutin kuposa hydroquinone.
Ili ndi kukwiya kochepa ndipo imatha kuwonjezeredwa momasuka kuzinthu zosamalira khungu ndi malire apamwamba mpaka 7%.
Mamolekyu omwe amagwira ntchito a arbutin amatha kulowa pakhungu kuti alamulire kwambiri, ndipo amatha kuchiza chloasma, mawanga akuda, madontho a dzuwa, ndi mtundu wa pigmentation wotsalira chifukwa cha kusagwirizana ndi mankhwala.
Onse ali ndi mphamvu zochiritsira zochiritsira, koma ngati ndendeyo ili yotsika kwambiri, kukhazikika kwa zotsatirazo kumakhala kofooka, kotero kuti 5% ndende ndiyo njira yotetezeka kwambiri komanso yothandiza kwambiri yowunikira.
Kuchuluka kwa 5% kumathamanga kuposa vitamini C pakuwunikira mawanga, ndipo kuwunikira kumakhala kokhazikika ndipo sikungayambitse khungu.

Ndipotu palibe chifukwa chodera nkhawa. Mayesero awonetsa kuti arbutin okha omwe ali ndi ndende yopitilira 7% amatha kumva kuwala. Chifukwa chake, 7% ndiyofunika kwambiri pachitetezo. Pali malamulo omveka bwino okhudza zowonjezera zowonjezera muzinthu zosamalira khungu. Pazipita ndende malire ndi 7%. Mkati mwa izi, arbutin sikokwanira kuyambitsa photosensitivity, kotero singagwiritsidwe ntchito popanda chitetezo chopepuka.
Ikalowetsedwa pakhungu ndikuwola ndi kuwala, imatsitsidwa kukhala hydroquinone, ndikupanga kuyanika. Kuchuluka kwa hydroquinone muzinthu zosamalira khungu za arbutin ndi zosakwana 20 ppm (ndiko kuti, magawo 20 pa miliyoni). Pansi pa malire otsika chotere, hydroquinone sichingabweretse zotsatira zoyipa monga mdima wa khungu.
Ngati mukuwopa kugwiritsa ntchito mankhwala osamalira khungu masana chifukwa chakuti ali ndi arbutin, ndiye kuti simukuyenera kutero, pokhapokha ngati mankhwala osamalira khungu omwe ali ndi arbutin amawonjezeranso zinthu zina zosamalira khungu zomwe ziyenera kutetezedwa ku kuwala.
Mwachidule, muyenera kusankha mankhwala osamalira khungu kuchokera kuzinthu zodalirika, ndipo ziribe kanthu zomwe mumagwiritsa ntchito, gwiritsani ntchito chitetezo cha dzuwa masana.
