Ngo-1998, i-FDA yavuma ukusetshenziswa kwaleli gama kwabanye abakhiqizi be-laser yokususa izinwele kanye nemishini yokukhanya okushukunyiswayo. Ukususwa kwezinwele okuhlala njalo akusho ukususwa kwazo zonke izinwele ezindaweni zokwelapha. Ukuncipha kwesikhathi eside, okuzinzile kwenani lezinwele ezikhula kabusha ngemva kohlelo lokwelashwa.
Uma wazi ukwakheka kwezinwele kanye nesigaba sokukhula, kuyini ukwelashwa nge-laser futhi kusebenza kanjani?
Ama-Laser aklanyelwe ukunciphisa izinwele unomphela akhipha ukukhanya okumuncwa yi-melanin ku-folicle yezinwele (i-dermal papilla, amaseli e-matrix, ama-melanocyte). Uma isikhumba esizungezile silula kunombala wezinwele, amandla amaningi e-laser azogxila ku-shaft yezinwele (i-selective photothermalysis), ayibhubhise ngempumelelo ngaphandle kokuthinta isikhumba. Uma i-follicle yezinwele isibhujisiwe, izinwele zizowa kancane kancane, khona-ke umsebenzi wokukhula kwezinwele osele uzophendukela esigabeni se-anagen, kodwa uphenduke ube mncane kakhulu futhi uthambile ngenxa yokuntuleka kwezakhamzimba ezanele zokusekela ukukhula kwezinwele kwempilo.
Yibuphi ubuchwepheshe obufaneleka kakhulu ekususeni izinwele?
Ukususwa kwamakhemikhali ngokwesiko, ukususwa komshini noma ukususwa kokushefa nge-tweezer konke lokhu kusika izinwele esikhumbeni kwenza isikhumba sibukeke sibushelelezi kodwa akunamthelela ku-folicle yezinwele, yingakho izinwele zikhula ngokushesha, ziqine kakhulu kunangaphambili ngenxa yokuvuselelwa kwazo okubangela izinwele eziningi esigabeni se-anagen. Ngaphezu kwalokho, lezi zindlela zendabuko zingabangela ukulimala kwesikhumba, ukopha, ukuzwela kwesikhumba nezinye izinkinga. Ungabuza ukuthi i-IPL ne-laser zithatha isimiso esifanayo sokwelashwa, kungani ukhethe i-laser?
Uyini umehluko phakathi kwe-Laser ne-IPL?
I-IPL imele 'ukukhanya okunamandla okushaywa' futhi inezinhlobo ezithile zomkhiqizo ezifana ne-SIPL, i-VPL, i-SPL, i-OPT, i-SHR okuyizinto zobuchwepheshe obufanayo. Imishini ye-IPL ayiwona ama-laser ngoba ayiwona ama-wavelength awodwa. Imishini ye-IPL ikhiqiza ububanzi be-wavelength obungafinyelela ukujula okuhlukile kwezicubu zesikhumba, bumuncwe yizinhloso ezahlukene ikakhulukazi kufaka phakathi i-melanin, i-hemoglobin, amanzi. Ngakho-ke ingafudumeza zonke izicubu ezizungezile zifinyelele imiphumela eminingi efana nokususwa kwezinwele nokuvuselelwa kwesikhumba, ukususwa kwemithambo yegazi, ukwelashwa kwama-acne. Kodwa ukwelashwa ngokuthuthumela kuya ebuhlungu ngenxa yamandla ayo amakhulu okukhanya kwe-broad spectrum, ingozi yokusha kwesikhumba nayo izoba phezulu kune-semiconductor diode lasers.
Umshini ojwayelekile we-IPL usebenzisa isibani se-xenon ngaphakathi kwesibambo esikhipha ukukhanya, kukhona ikristalu le-sapphire noma le-quartz ngaphambili kokuthinta isikhumba, udlulise amandla okukhanya futhi wenze ukupholisa ukuze kuvikelwe isikhumba.
(ukukhanya ngakunye kuzoba umphumela owodwa kufaka phakathi ama-pulse amaningi), isikhathi sokuphila sesibani se-xenon (ikhwalithi yaseJalimane cishe ama-pulse angu-500000) sizoba ngaphansi ngokuphindwe kaningi kunebha ye-laser ye-diode laser.
uhlobo (i-marco-channel noma i-micro-channel general kusuka kuzigidi ezimbili kuya kwezingu-20). Ngakho-ke ama-laser okususa izinwele (okungukuthi i-Alexandrite, i-Diode, kanye ne-ND:Yag) avame ukuba nesikhathi eside sokuphila futhi azizwa ekhululekile kakhudlwana ngokwelashwa kwezinwele okungafunwa. Lawa ma-laser akhethekile asetshenziswa esikhungweni sokususa izinwele sochwepheshe.
