Kushandiswa
Shandisa semushonga wekuderedza mifananidzo uye kugadzira; semushonga wekugadzirisa phosphate shoma; semushonga wekudzivirira ganda kubva muganda.
Hydroquinone chinhu chinobvisa ruvara chinoshandiswa mumakirimu ekutsvukisa. Hydroquinone inosangana neokisijeni nekukurumidza uye inova brown kana yaiswa mumhepo. Kunyangwe ichiitika zvega, chigadzirwa ichi ndicho chinowanzoshandiswa muzvizoro. Kushandiswa paganda kunogona kukonzera allergic reaction uye kuwedzera kunzwa kwezuva paganda. Hydroquinone inogona kukonzera kenza uye ine chekuita nekukonzera ochronosis, kuchinja kweruvara rweganda. US FDA yakarambidza hydroquinone kubva muzvigadzirwa zve oTC cosmetic, asi inobvumira 4 muzana muzvigadzirwa zvechiremba. Kushandiswa kwayo muzvizoro hakubvumirwi mune dzimwe nyika dzeEurope nemuAustralia.
