Ishingiro ry'iminkanyari ni uko uko gusaza bigenda byiyongera, ubushobozi bwo kwisana bw'uruhu bugenda bugabanuka buhoro buhoro. Iyo imbaraga zimwe zo hanze zipfundikiye, igihe cy'uko ibimenyetso bishira buhoro buhoro kugeza igihe bitazongera kuboneka. Ibintu bituma uruhu rusaza bishobora kugabanywamo ubwoko bubiri: ubw'umwimerere n'ubw'inyuma. Nta tandukaniro rinini riri hagati y'abantu basanzwe bafite gusaza kw'umwimerere. Uretse urubyaro ruterwa n'ubusembwa buke bwihariye bw'uturemangingo, urwego rw'imirire y'abantu ba none Ibintu nk'uburyo ntabwo bihagije kugira ngo bigire itandukaniro rikomeye kuri buri wese.
Gusaza kw'inyuma gutandukanye cyane mu bice bitandukanye. Isura igaragara ku rugero ntarengwa rw'izuba, bityo gusaza kw'inyuma byitwa photoaging. Imirasire ya ultraviolet iri mu rumuri ishobora kwangiza imigozi y'uruhererekane ako kanya. Imirasire ya ultraviolet nayo yangiza imikorere y'uruhu, bigatuma amazi atakaza menshi, kandi kuma kw'aho hantu bizagabanya ubushyuhe bwa stratum corneum. Muri iki gihe, gusimbuka gato bizasiga uduce duto.
Iyo ukiri muto, kubera ko ubushobozi bwawe bwo gusana buba bukomeye, imikorere yawe y'umubiri izasubira vuba uko yari imeze mbere. Uko uruhu rugenda rusaza, ubushobozi bwo gusana buragabanuka buhoro buhoro, kandi ibikoresho byo kwita ku ruhu ntibiba bigikora.
Isesengura ry'uruhu rya Meicetishobora kumenya iminkanyari, imirongo mito ku maso hashingiwe ku buhanga n'ikoranabuhanga ryo gufata amashusho.
