Turagira inama ko kurinda izuba ari bumwe mu buryo bwiza bwo kwirinda gusaza vuba kandi ko ari bwo buryo bwa mbere bwo kwirinda mbere yuko tugura ibikoresho bikomeye byo kwita ku ruhu. Ariko abakiriya bavuga ko batambara amavuta yo kwisiga izuba kuko bafite impungenge ku bijyanye n'umutekano w'ibintu biri mu bikoresho byo kwirinda izuba.
Niba utabizi neza, komeza usome itandukaniro riri hagati y'amavuta y'izuba akoreshwa mu binyabutabire n'ay'umubiri (mineral) ndetse n'impamvu tubona ko amavuta y'izuba ari yo meza yo gukoresha ku ruhu rwawe.
Ariko mbere na mbere, ni ngombwa gusobanura ijambo "chemical" kuko rimwe na rimwe hashobora kubaho igitekerezo kitari cyo cy’uko "chemicals" zose ari mbi. Ariko, twe, kimwe n’ibindi byose bitukikije tugizwe n’ibintu bihumanya ikirere, ndetse n’amazi ni ikintu kidasanzwe, bityo nta kintu na kimwe gishobora gushyirwa mu cyiciro cy’ibidafite "chemicals". Aho hari ubwoba ku bikoresho byo kwita ku ruhu, ibi muri rusange bifitanye isano n’ikintu gikozwe mu bintu bihumanya ikirere. Muri iki gihe, twakoresha amagambo, 'nta burozi' iyo tugaragaza ibintu byemewe ko bishobora gukoreshwa neza.
Indabyo zisiga izuba hakoreshejwe imiti ni iki?
Imiti irinda izuba ikora mu kwinjiza mu ruhu, kandi iyo imirasire ya UV ihuye na suncream, habaho ingaruka zikuraho imirasire ya UV mbere yuko uruhu rwawe rwangirika. Byitwa chemical, kuko hari ingaruka za chemical zibaho kugira ngo zirinde izuba.
Ibikoresho bikunze gukoreshwa cyane ni oxybenzone, avobenzone, na octinoxate kandi nubwo amazina yabyo bigoye kuyavuga, ibi bikoresho bikora nk'ikirungo kugira ngo byinjize imirasire ya ultraviolet yangiza.
Indabyo zirinda izuba zifite ubutare ni iki?
Imiti irinda izuba ikoresheje amabuye y'agaciro n'iy'umubiri ni imwe kandi iba hejuru y'uruhu kandi ikora nk'ikirinda imirasire y'izuba. Imiti irinda izuba ikoresha ibintu bibiri by'ingenzi karemano - zinc oxyde na titanium dioxide - kandi muri rusange ifite ibintu bike birimo ugereranyije n'amavuta yo kwisiga ku zuba.
Wamenya ute niba amavuta akingira izuba ari amabuye y'agaciro cyangwa imiti?
Ushobora kumenya ubwoko bw'amavuta yo kwisiga akingira izuba ufite uhindukiza icupa cyangwa ikibindi hanyuma ukareba urutonde rwa INCI (ibikubiye mu gipfunyika) inyuma y'ipaki kugira ngo urebe ibintu bikora.
Kuki uhitamo amavuta yo kwisiga akingira izuba?
Nkuko twabivuze haruguru, hari abantu bafite impungenge ku birebana n'ibintu birimo uburozi biri mu mavuta yo kwisiga ku zuba bityo bagahitamo gukoresha mineral SPF kuko ziba hejuru y'uruhu aho kwinjizwamo. Uretse ibibazo by'ibikubiye muri ayo mavuta, uruhu rworoshye, cyangwa abafite ubwivumbure ku mavuta amwe n'amwe yo kwisiga ku zuba cyangwa abarwayi b'ibiheri bashobora no guhitamo ibintu byoroshye biri mu mavuta yo kwisiga ku zuba n'urutonde rw'ibintu bigufi.
Hanyuma hari uburyo bwo gukoresha. Niba urimo kwishima ngo usohoke ahantu hose, ushobora guhitamo amavuta yo kwisiga afite ubuziranenge kuko bitandukanye n'amavuta yo kwisiga afite ubuziranenge, agomba kwinjira mu ruhu neza mbere yuko agira akamaro (afata iminota irenga 15), amavuta yo kwisiga afite ubuziranenge agira akamaro ako kanya akimara gushyirwaho.
Akamaro k'amavuta yo kwisiga ku zuba afite imyunyungugu
Irinda amazi iyo ikoreshejwe ku ruhu - hamwe n'amavuta y'izuba yaba ay'imiti cyangwa ay'imyunyu ngugu ugomba kongera kuyakoresha iyo uvuye muri pisine cyangwa mu nyanja.
Uburinzi bwa UVA na UVB – zinc oxide, ikora muri mineral suncream, iraboneka neza cyane bityo itanga uburinzi bwiza bwa UVA na UVB kuko itazigera itakaza imbaraga zayo zo kurinda iyo ihuye n'urumuri rwa UV. Ibi ni ingenzi mu kwirinda gusaza imburagihe n'ibibazo by'ubuzima bw'uruhu. Titanium dioxide itanga uburinzi buke bwa UVA bityo uzabona zinc oxide kenshi ku rutonde rw'ibintu bikoreshwa mu gusiga suncream.
Ifite umutekano kandi irinda ibidukikije - ibintu by'ingenzi biri mu mavuta menshi ya suncream ashobora kwangiza ibinyabuzima byo mu mazi n'amabuye ya korali mu gihe ibintu by'ingenzi bya suncream muri rusange bifatwa nk'ibidahungabanya ibidukikije kandi ntibishobora gutuma korali ihinduka cyangwa ngo bigire ingaruka ku buzima bwo mu mazi.
Oxyde ya zinc ifitanye isano n'inyungu nyinshi ku buzima - Ishobora kugabanya uburibwe (ni byiza niba waratwitswe n'izuba), ntizangiza imyenge kuko idatera indwara kandi ifite ubushobozi bwo kurwanya indwara ziterwa na bagiteri n'ububyimbirwe bishobora gutuma uruhu rugumana uburibwe, iminkanyari igaragara kandi igafasha mu kurwanya ibiheri.
Twizeye ko iyi blog yagufashije gusobanukirwa neza itandukaniro riri hagati y’ibicuruzwa bitandukanye birinda izuba biri hanze aha.
