Indi ndwara yo gutandukanya ibara ry’uruhu ijyana no kubona urumuri rw’izuba ni ugutera ibara ry’uruhu nyuma yo kubyimba (PIH). Ibi bibaho iyo uruhu rubyimbye, nko mu gihe cy’ibiheri cyangwa eczema, maze melanocytes mu gace kafashwe zigatanga melanin nyinshi. Kubera iyo mpamvu, uduce twahinduye ibara cyangwa utudomo dushobora kuguma ku ruhu nyuma y’uko ububyimbirwe bugabanutse.
Isano iri hagati y'imirasire ya UV n'indwara zo gutandukanya ibara ry'uruhu igaragaza akamaro ko kurinda uruhu imirasire yangiza y'izuba. Ibi bishobora gukorwa wambaye imyenda irinda uruhu, nk'amashati n'ingofero by'amaboko maremare, kandi ugakoresha amavuta yo kwisiga afite SPF nibura 30. Ni ngombwa kandi kwirinda kwibasirwa n'izuba igihe kirekire, cyane cyane mu masaha y'akazi kenshi iyo UV ifite igipimo cyo hejuru.
