Yini okudingeka ukwazi mayelana nokususwa kwezinwele ze-laser?

Umjikelezo Wokukhula Kwezinwele:Isigaba sokukhula, isigaba seCatagen, isigaba sokuphumula

Ukususwa kwezinwele ze-Laser kusebenza kuphela izinwele esigabeni sokukhula futhi kunomphumela omncane ezigabeni ze-catagen ne-telogen.Ngakho-ke, ukususwa kwezinwele ze-laser kudinga izikhathi ezi-3 kuya kwezi-5 ukuze umphumela usebenze.Abantu abaningi abasoze badinga ukususa izinwele futhi empilweni yabo.Iqiniso liwukuthi ngemva kokususwa kwezinwele ze-laser, kungakwazi ukuzinzisa kuphela inani lokuvuselelwa kwezinwele endaweni yokwelapha ezingeni eliphansi kunangaphambili isikhathi eside ngemva kokwelashwa.Ezinye izindawo zokususa izinwele zingase zibe nenani elincane le-villi enhle, engabonakali nenombolo encane.

Isimiso: Ithiyori ekhethiwe ye-Photothermolysis

Lo mbono ubhekisela eqinisweni lokuthi izinto zikhiqiza izici ezikhethekile zamandla okushisa lapho zikhanyiswa ukukhanya okubonakalayo.Isici sawo esiyinhloko ukuthi ukukhanya kuphela kombala onikeziwe kungamuncwa into, kuyilapho ukukhanya kweminye imibala kuboniswa noma kudluliselwa.

Ubude begagasi

I-laser ye-semiconductor: Ubude be-wavelength: 808nm/810nm i-double-pulse laser ingakhuphula kancane izinga lokushisa kwesikhumba esikhishwe imisebe, ithambile esikhumbeni, futhi ithuthukise ukusebenza kahle kokukhipha izinwele ngaphandle kokubangela ubuhlungu nokunye ukusabela okungekuhle.

I-Alexandrite laser: Ubude begagasi: 755nm, amandla aphezulu.Uma isikhathi sokufaka iqhwa singeside ngokwanele, izimpawu ezingezinhle ezifana ne-erythema namabhamuza zivame ukwenzeka.

Ukukhanya kwe-pulsed okunamandla: Ubude be-waveleng: 480nm ~ 1200nm.Ubude begagasi obufushane bumuncwa i-melanin ku-epidermis kanye ne-haft shaft, ihlakaza ingxenye yamandla ebusweni besikhumba, futhi amandla asele asebenza ku-melanin ezimpandeni zezinwele.

I-laser ye-YAG: Ubude be-waveleng: 1064nm.Ubude begagasi obubodwa.Ubude begagasi bungena kancane futhi bungakwazi ukugxila ezinhlakeni zezinwele ezijulile.Kuyasiza esikhumbeni esimnyama, izinwele nezindebe.Izindebe nazo zifanelekile ngoba izinwele zincane futhi zilula ngombala, zine-melanin encane ezimpandeni zezinwele kanye nokumuncwa okungalungile kokukhanya.Izinwele ziminyene kakhulu futhi ziminyene futhi zinemelanin eningi.

Ama-laser angamaza amathathu ahambisana kakhulu nemishini yokususa izinwele.Ukumuncwa, ukungena, nokumbozwa yizici ezibalulekile lapho usebenzisa ukwelashwa nge-laser ukususa izinwele.Le laser inikeza amaza okwanele okukhipha izinwele.Umgomo wokusebenzisa ama-lasers angama-wavelength amathathu "okuningi, kungcono."Ukuhlanganisa ama-wavelength amathathu kulindeleke ukuthi kukhiqize imiphumela engcono ngesikhathi esingaphansi kwe-laser eyodwa yamaza.Ubuchwepheshe belaser ye-triple diode bunikeza odokotela isixazululo esididiyelwe lapho besebenzisa amalaser.Le laser entsha inikeza izinzuzo zamaza amaza amathathu ahlukene kudivayisi eyodwa.I-handpiece yale divayisi ye-laser ifinyelela ekujuleni okuhlukene ngaphakathi kwe-follicle yezinwele.Ukusebenzisa ama-wavelength amathathu ahlukene ndawonye kungase kuveze imiphumela enenzuzo mayelana nalawa mapharamitha.Ukunethezeka nokunethezeka komtholampilo akubekeki engcupheni uma kusetshenziswa amalaser anezendlalelo ezintathu ze-diode ekususeni izinwele.Ngakho-ke, i-laser ye-wavelength diode laser ingaba inketho ebanzi yokususwa kwezinwele.Le laser ingaba yinzuzo ikakhulukazi kubantu abanesikhumba esimnyama.Inekhono lokungena elijule kakhulu futhi isebenza ezindaweni ezijule njengesikhumba, amakhwapha, nezitho zangasese.Ukupholisa okuphumelelayo ngaphakathi kwedivayisi kwenza inqubo yokususa izinwele icishe ingabi nabuhlungu.Manje i-laser entsha ye-pulsed 940 nm diode esetshenziselwa ukususa izinwele ezinhlotsheni zesikhumba zase-Asia.
