1. Mbere ya byose, urumva urumuri UV aricyo? Ikora iki?
UV ni impfunyapfunyo ya Ultraviolet Imirasire, cyangwa urumuri ultraviolet, hamwe nuburebure bwumurambararo wa 100 kugeza 400 nm, aribwo buryo bwa elegitoroniki yumuriro hagati ya X-yumucyo numucyo ugaragara. Ibi bivuze ko urumuri ari urumuri rwingufu rwinjira kandi rutanga ubushyuhe kumubiri.
Kwangirika kwizuba ryuruhu rwumuntu ahanini bituruka kuri ultraviolet A (UVA) na ultraviolet B (UVB). UVA ni iy'umuraba muremure, ikora kumurongo wimbitse wuruhu, ibikorwa biratinda, ariko birashobora gutera umwijima inshuro imwe. UVB ni iyumuvuduko wo hagati, ikora hejuru yuruhu, ingaruka byihuse. Irashobora gukangura uruhu rwa keratinocytes, kugirango imiyoboro yamaraso yaguke, yongere umuvuduko wamaraso, iyambere izaba umutuku, hanyuma buhoro buhoro ihinduka umukara. Muri make rero, UVB iganisha kuri "umutuku izuba" naho UVA iganisha "izuba ryijimye".
Ingaruka: Muri rusange ikoreshwa mubuvuzi mu kuvura ibisazi byera, bivuze ko binyuze muri uku kumurika urumuri ultraviolet, gukora mu buryo butaziguye ikibara cyera munsi yuruhu rwa tyrosine enzyme itera umusaruro wa melanin, uruhu rwera rukaba umukara.
Turashobora kubona ibintu byinshi UV yoroheje ivura ibikoresho byasaze byera kuri enterineti, dushobora kugerageza gushakisha.
2. Ni uruhe ruhare rwa bamwe mubakora mugukoresha urumuri rwa UV muri imashini isesengura uruhu?
Niba urumuri UV rwangiza cyangwa rutangiza uruhu, ubucuruzi bumwe na bumwe ku isoko bukoresha urumuri rwa UV ku bikoresho byerekana uruhu bikoreshwa cyane cyane mu kureba ibibara byamabara hamwe nuduce (hejuru yuruhu) ibi bintu 2 nibintu bike mubuhanga bwa tekiniki mumushinga wo gutahura, kubera iki? Ibara ryuruhu urashobora kuboneka binyuze murwacu Imashini ya Magic Mirror Isesengura Imashini, barashobora kandi kubona ikibanza, kuki bagomba gukenera igikoresho kugirango bamenye, nka aIgikoresho cyo gusesengura uruhutwibwira ko ari byiza cyane kubona ikibara cyamabara munsi ya derm.
