Mu 1998, FDA yemeje ikoreshwa ry'iri jambo ku bakora imashini zikuraho umusatsi za laser n'ibikoresho by'urumuri bikoresha pulsed. Gukuraho umusatsi burundu ntibisobanura gukuraho umusatsi wose mu bice bivurirwamo. Kugabanuka kw'igihe kirekire kandi ku buryo buhamye k'umubare w'umusatsi wongera gukura nyuma yo kuvurwa.
Iyo uzi imiterere y'umusatsi n'igihe ukura, none se ubuvuzi bwa laser ni iki kandi bukora bute?
Imirasire ya laser yagenewe kugabanya umusatsi burundu isohora urumuri rwinjizwa na melanin mu musatsi (dermal papilla, matrix cells, melanocytes). Iyo uruhu rukikije rworoshye kurusha ibara ry'umusatsi, ingufu nyinshi za laser zizagera mu gice cy'umusatsi (selective photothermalysis), zikawusenya neza nta ngaruka ku ruhu. Iyo umusatsi umaze kwangirika, umusatsi uzagenda ugabanuka buhoro buhoro, hanyuma ibikorwa byo gukura k'umusatsi bisigaye bizahinduka ikiciro cya anagen, ariko bigahinduka bito cyane kandi byoroshye bitewe no kutagira intungamubiri zihagije zishyigikira imikurire y'umusatsi.
Ni ikoranabuhanga irihe rikwiriye cyane mu gukuraho umusatsi?
Uburyo gakondo bwo gukata umusatsi hakoreshejwe imiti, gukata imisatsi hakoreshejwe uburyo bwa "mechanical epilation" cyangwa "shaving epilation" hakoreshejwe "tweezer" byose bigabanya umusatsi ku ruhu bituma uruhu rusa neza ariko nta ngaruka ku musatsi, niyo mpamvu umusatsi ugaruka vuba, ndetse ukaba ukomeye kurusha mbere bitewe n'uburyo bwo kuwutera. Ikindi kandi, ubu buryo gakondo bushobora gutera ububabare bw'uruhu, kuva amaraso, kumva uruhu neza n'ibindi bibazo. Ushobora kwibaza ko IPL na "laser" bifatwa nk'uburyo bumwe bwo kuvura, kuki wahitamo "laser"?
Itandukaniro riri hagati ya Laser na IPL ni irihe?
IPL isobanura 'urumuri rwinshi rwa pulsed' kandi ifite ubwoko butandukanye nka SIPL, VPL, SPL, OPT, SHR byose ni ikoranabuhanga rimwe. Imashini za IPL si laser kuko uburebure bwazo butari bumwe. Imashini za IPL zikora uburebure bwinshi bw'uburebure bushobora kugera ku burebure butandukanye bw'uruhu, bugatwarwa n'ibintu bitandukanye birimo melanin, hemoglobin, amazi. Bityo zishobora gushyushya ingingo zose zikikije zigera ku musaruro mwinshi nko gukuraho umusatsi no kuvugurura uruhu, gukuraho imitsi y'amaraso, kuvura ibiheri. Ariko uburyo bwo kuvura butuma umuntu yumva ababara bitewe n'imbaraga ze zikomeye z'urumuri rwinshi, ibyago byo gushya uruhu bizaba byinshi kuruta laser za semiconductor diode.
Imashini ya IPL ikoresha itara rya xenon imbere mu mugozi, igice cy'urumuri gisohoka, imbere hagaragara ikirahure cya safiro cyangwa quartz, uruhu rwohereza ingufu z'urumuri kandi rukonjesha kugira ngo rurinde uruhu.
(Buri rumuri ruzaba rutanga umusaruro umwe harimo n'amatara menshi), igihe cy'itara rya xenon (ubuziranenge bw'Abadage bugera kuri 500000) kizaba gito inshuro nyinshi ugereranyije n'umurongo wa laser wa diode.
Ubwoko bwa (marco-channel cyangwa micro-channel general kuva kuri miliyoni 2 kugeza kuri 20). Bityo, laser zo gukuraho imisatsi (urugero: Alexandrite, Diode, na ND:Yag) zikunda kugira igihe kirekire kandi zikumva zoroshye kuvura imisatsi idakenewe. Izi laser zikoreshwa mu kigo cy’inzobere mu gukuraho imisatsi.
