M'zaka zaposachedwa, ndikuchulukitsa kwachuma, mphamvu ya anthu pazachilengedwe ikuwonjezeka, zomwe zimapangitsa kuti ozoni wosanjikiza ayambe kuchepa. Mphamvu ya kuwala kwa ultraviolet yomwe imafikira padziko lapansi dzuwa likuwonjezeka, zomwe zimawopseza mwachindunji thanzi la anthu. M'moyo watsiku ndi tsiku, kuti muchepetse kuwonongeka kwa ma radiation pa khungu, Anthu ayenera kupewa kuwonetsedwa ndi dzuwa ndikupita kunja masana dzuwa likuwala, kuvala zovala zoteteza, komanso kugwiritsa ntchito zodzoladzola zowotcha dzuwa patsogolo pa chitetezo cha dzuwa, pakati pawo , kugwiritsa ntchito zodzikongoletsera zoteteza ku dzuwa ndi njira zomwe zimagwiritsidwa ntchito kwambiri podziteteza ku UV, zimatha kuteteza kuwala kwa dzuwa kuyambitsa erythema ndi kuvulala kwa inshuwaransi, kupewa kapena kuchepetsa kuwonongeka kwa DNA, Kugwiritsa ntchito zodzoladzola zowotchera dzuwa kumathandizanso kuononga kuwonongeka kwa khansa isanachitike, kumatha kuchepetsa kwambiri zochitika za khansa ya dzuwa.
Sunscreen ndi mtundu wa mankhwala omwe amapezeka ndi kuyamwa kwa dzuwa, kotchedwanso uv absorbent. Omwe amagwiritsidwa ntchito kwambiri ndi p-methoxy cinnamic acid ester, zotumphukira za camphor, benzotriazole ndi oakelin, ndi zina zambiri. Amagwiritsidwa ntchito limodzi ndi zowotchera dzuwa kuti zikuthandizeni kuteteza dzuwa.
