Ngo-1998, i-FDA yagunyaza ukusetshenziswa kwaleli gama kwabanye abakhiqizi bezinsimbi zokususa izinwele kanye nemishini yokukhanya eshaywayo.Ukususwa kwezinwele okungapheli akusho ukuqedwa kwazo zonke izinwele ezindaweni zokwelashwa.Ukunciphisa isikhathi eside, okuzinzile kwenani lezinwele ezikhula kabusha ngemva kombuso wokwelapha.
Uma wazi i-anatomy yezinwele kanye nesiteji sokukhula ke Iyini i-laser therapy futhi isebenza kanjani?
Amalaza aklanyelwe ukuncishiswa kwezinwele unomphela akhipha amaza okukhanya amuncwa i-melanin embotsheni yezinwele (i-dermal papilla, amaseli e-matrix, ama-melanocyte).Uma isikhumba esizungezile silula kunombala wezinwele, amandla amaningi e-laser azogxila ku-shaft yezinwele (i-photothermalysis ekhethiwe), ayibhubhise ngokuphumelelayo ngaphandle kokuthinta isikhumba.Lapho i-follicle yezinwele isicekeleke phansi, izinwele zizowa kancane kancane, khona-ke umsebenzi osele wokukhula kwezinwele uzophendukela esigabeni se-anagen, kodwa uphenduke ube mncane kakhulu futhi uthambile ngenxa yokungabi nomsoco owanele ukuxhasa ukukhula kwezinwele.
Yibuphi ubuchwepheshe obufaneleka kakhulu ukususa izinwele?
I-epilation yamakhemikhali evamile, i-mechanical epilation noma i-sheve epilation nge-tweezer konke ukugunda izinwele ku-epidermis kwenza isikhumba sibukeke sibushelelezi kodwa singathinteki embotsheni yezinwele, yingakho izinwele zikhula ngokushesha, ziqine nakakhulu kunangaphambili ngenxa yesizathu esishukumisayo. izinwele zibe yisiteji se-anagen.Ngaphezu kwalokho, lezi zindlela zendabuko zingabangela ukulimala kwesikhumba, ukopha, ukuzwela kwesikhumba nezinye izinkinga. Ungase ubuze ukuthi i-IPL ne-laser zithatha isimiso sokwelashwa esifanayo, kungani ukhetha i-laser?
Uyini umehluko phakathi kweLaser ne-IPL?
I-IPL imele 'i-intense pulsed light' futhi inokuhluka okuthile okunegama elinjenge-SIPL, VPL, SPL, OPT, SHR konke okuwubuchwepheshe obufanayo.Imishini ye-IPL ayiwona ama-laser ngoba imishini yayo ayiyona i-wavelength.IPL eyodwa ikhiqiza umkhawulokudonsa obanzi we-wavelength ongafinyelela ukujula okuhlukene kwezicubu zesikhumba, umuncwe izinhloso ezihlukene ikakhulukazi ezihlanganisa i-melanin, i-hemoglobin, amanzi.Ngakho ingashisisa zonke izicubu ezizungezile. finyelela imiphumela esebenza ngezinto eziningi njengokususwa kwezinwele nokuvuselelwa kwesikhumba, ukususwa kwemithambo yemithambo, ukwelashwa kwezinduna.Kodwa ukwelashwa okuncinza kube nomuzwa obuhlungu ngenxa yamandla anamandla okukhanya okubanzi okubanzi, ingozi yokushiswa kwesikhumba nayo izoba phezulu kune-semiconductor diode lasers.
Umshini jikelele we-IPL usebenzisa isibani se-xenon ngaphakathi kwesibambo esikhipha ukukhanya, kukhona isafire noma ikristalu ye-quartz ngaphambili ukuthinta isikhumba kudlulise amandla okukhanya nokwenza ukupholisa ukuvikela isikhumba.
(ukukhanya ngakunye kuzoba okukhiphayo okukodwa kufaka phakathi ama-pulses amaningi), isibani se-xenon(ikhwalithi yaseJalimane cishe ama-pulses angu-500000) isikhathi sokuphila sizoba ngaphansi kaningi kunebha ye-laser ye-diode
(i-marco-channel noma i-micro-channel general kusuka ezigidini ezi-2 kuye kwezingu-20) uhlobo.Ngakho-ke ama-laser okususa izinwele (okungukuthi, i-Alexandrite, i-Diode, ne-ND:Izinhlobo ze-Yag) avame ukuba nokuphila isikhathi eside nomuzwa okhululekile wokwelashwa kwezinwele okungafunwa.Lawa ma-lasers akhethekile. sebenzisa esikhungweni sokususa izinwele ezichwepheshile.
