Ngo-1998, i-FDA yavuma ukusetyenziswa kweli gama kwabanye abavelisi bee-laser zokususa iinwele kunye nezixhobo zokukhanya okushukumayo. Ukususwa kweenwele okuhlala ixesha elide akuthethi ukususwa kwazo zonke iinwele kwiindawo zonyango. Ukuncipha okuzinzileyo kwexesha elide kwenani leenwele ezikhula kwakhona emva kwenkqubo yonyango.
Xa usazi indlela iinwele ezikhula ngayo kunye nenqanaba lokukhula, yintoni unyango lwelaser kwaye lusebenza njani?
Iilaser ezenzelwe ukunciphisa iinwele ngokusisigxina zikhupha ukukhanya okufunxwa yi-melanin kwi-folicle yeenwele (i-dermal papilla, ii-matrix cells, ii-melanocytes). Ukuba ulusu olujikelezileyo lukhaphukhaphu kunombala weenwele, amandla e-laser amaninzi aya kugxila kwi-shaft yeenwele (i-selective photothermalysis), ayitshabalalise ngempumelelo ngaphandle kokuchaphazela ulusu. Nje ukuba i-follicle yeenwele itshatyalaliswe, iinwele ziya kuwa kancinci kancinci, emva koko umsebenzi wokukhula kweenwele oseleyo uya kutshintsha ube kwinqanaba le-anagen, kodwa uguquke ube mncinci kakhulu kwaye uthambile ngenxa yokungabikho kwesondlo esaneleyo sokuxhasa ukukhula kweenwele.
Yeyiphi iteknoloji efanelekileyo kakhulu yokususa iinwele?
Ukususwa kweekhemikhali zemveli, ukususwa kweenwele ngoomatshini okanye ukususwa kweenwele nge-tweezer zonke ezi zisika iinwele kwi-epidermis zenza ulusu lubukeke luthambile kodwa alunampembelelo kwi-folicle yeenwele, yiyo loo nto iinwele zikhula ngokukhawuleza, ziqine ngakumbi kunangaphambili ngenxa ye-stimuli ebangela iinwele ezininzi zibe kwinqanaba le-anagen. Ngaphezu koko, ezi ndlela zemveli zinokubangela ukwenzakala kwesikhumba, ukopha, ukuva ulusu kunye nezinye iingxaki. Ungabuza ukuba i-IPL kunye ne-laser zithatha umgaqo ofanayo wonyango, kutheni ukhetha i-laser?
Yintoni umahluko phakathi kweLaser kunye ne-IPL?
I-IPL imele 'ukukhanya okunamandla okutsalwa' kwaye ineempawu ezahlukeneyo ezifana ne-SIPL, VPL, SPL, OPT, SHR zonke ezibuchwepheshe obufanayo. Oomatshini be-IPL abangoo-laser kuba ayingoo-wavelength enye. Oomatshini be-IPL bavelisa ububanzi bobude bobude obunokufikelela kubunzulu obahlukeneyo bezicubu zesikhumba, bufunxwe ziinjongo ezahlukeneyo kubandakanya i-melanin, i-hemoglobin, amanzi. Ngaloo ndlela banokufudumeza zonke izicubu ezijikelezileyo ukufikelela kwiziphumo ezininzi ezifana nokususwa kweenwele kunye nokuvuselelwa kwesikhumba, ukususwa kwemithambo yegazi, unyango lwe-acne. Kodwa unyango olunentlungu ngenxa yamandla alo okukhanya anamandla, umngcipheko wokutsha kwesikhumba uya kuba phezulu kunee-semiconductor diode lasers.
Umatshini we-IPL oqhelekileyo usebenzisa isibane se-xenon ngaphakathi kwesibambo esikhupha ukukhanya, kukho ikristale yesafire okanye ye-quartz ngaphambili, ulusu ludlulisela amandla okukhanya kwaye lwenze ukupholisa ukukhusela ulusu.
(ukukhanya ngakunye kuya kuba yimveliso enye kuquka iipulses ezininzi), ixesha lobomi lesibane se-xenon (umgangatho waseJamani malunga neepulses ezingama-500000) liya kuba ngaphantsi ngokuphindwe kaninzi kune-laser bar ye-diode laser.
(i-marco-channel okanye i-micro-channel general ukusuka kwizigidi ezi-2 ukuya kwezingama-20). Ngoko ke, ii-laser zokususa iinwele (umz. i-Alexandrite, i-Diode, kunye ne-ND:Yag types) zihlala ixesha elide kwaye ziziva zikhululekile ngakumbi kunyango lweenwele olungafunekiyo. Ezi lasers zisetyenziswa ngokukodwa kwiziko lobuchwephesha lokususa iinwele.
