Ma radiation a Ultraviolet (UV) ndi mbali ya ma electromagnetic (kuwala) omwe amafika padziko lapansi kuchokera kudzuwa. Ili ndi mawonekedwe afupikitsa kuposa kuwala kowoneka, kupangitsa kuti isawonekere ndi maso amaliseche Ultraviolet A (UVA) ndiye kuwala kwakutali kwa UV komwe kumayambitsa kuwonongeka kwa khungu kosatha, kukalamba kwa khungu, komanso kungayambitse khansa yapakhungu. Ultraviolet B (UVB) ndi mtundu waufupi wa UV womwe umayambitsa kutentha kwa dzuwa, kuwonongeka kwa khungu, komanso kumayambitsa khansa yapakhungu.
Zoteteza ku dzuwa ndi mankhwala omwe amaphatikiza zinthu zingapo zomwe zimathandiza kuteteza kuwala kwa dzuwa kuti zisafike pakhungu. Mitundu iwiri ya radiation ya ultraviolet, UVA ndi UVB, imawononga khungu ndikuwonjezera chiopsezo cha khansa yapakhungu. Zodzitetezera ku dzuwa zimasiyana malinga ndi kuthekera kwawo kuteteza ku UVA ndi UVB.
Mafuta oteteza ku dzuwa angathandize kupewa khansa yapakhungu poteteza ku cheza choopsa cha dzuwa. Bungwe la American Academy of Dermatology limalimbikitsa aliyense kugwiritsa ntchito mafuta oteteza ku dzuwa omwe amapereka zotsatirazi: Chitetezo cha Broadspectrum (chimateteza ku UVA ndi UVB cheza) Sun Protection Factor (SPF) 30 kapena kuposerapo.
Diethylhexyl Butamido Triazonendi mankhwala omwe amayamwa mosavuta ma radiation a UVA ndi UVB ndipo amapezeka kawirikawiri muzoteteza ku dzuwa ndi zinthu zina zosamalira dzuwa.
Chifukwa cha kusungunuka kwake kwakukulu mumafuta ambiri odzikongoletsera, milingo yochepa yokha ndiyofunikira kuti muphatikizepo zosakaniza zokwanira kuti zifikire ma SPF apamwamba.
Amagwiritsidwa ntchito mpaka 10%. Imasefa kunyezimira kwa UVB, ndi kuwala kwa UVA.
Choyatsira cha UV cha Broad spectrum Chimapatsa Mphamvu Yoteteza Dzuwa Yabwino Kwambiri Imalumikizana bwino ndi Zosefera zina za UV. Mafuta odzola odzola Seums Mafuta Onunkhira Sopo Kukongola Usiku seramu Zodzikongoletsera za dzuŵa Zimapanga zinthu/ Zodzikongoletsera zamtundu Zosungunuka mu gawo la mafuta la emulsion Broad spectrum UV absorber Hydrophobic chilengedwe ndi kusungunuka kwake mu mafuta osavuta kupanga osamva madzi.
Diethylhexyl Butamido Triazonendi mankhwala opangidwa ndi triazine omwe amatha kuyamwa mosavuta ma radiation a UVA ndi UVB. Iscotrizinol imapezeka kawirikawiri mu sunscreen ndi zinthu zina zosamalira dzuwa.
