Cov plaub hau loj hlob: theem loj hlob, Catagen theem, so theem
Laser tshem tawm cov plaub hau tsuas yog siv tau rau cov plaub hau nyob rau theem kev loj hlob thiab muaj me ntsis cuam tshuam rau cov theem catagen thiab telogen.Yog li ntawd, laser tshem tawm cov plaub hau yuav tsum tau 3 mus rau 5 zaug rau cov nyhuv kom zoo.Ntau tus neeg yuav tsis tas yuav tshem cov plaub hau dua hauv lawv lub neej.Qhov tseeb yog tias tom qab laser tshem tawm cov plaub hau, nws tsuas tuaj yeem ua kom cov plaub hau rov ua dua tshiab hauv thaj chaw kho mob ntawm qis dua ua ntej rau lub sijhawm ntev tom qab kev kho mob.Qee qhov chaw tshem tawm cov plaub hau tej zaum yuav muaj me me ntawm cov villi zoo, uas tsis pom tseeb thiab tsawg.
Lub hauv paus ntsiab lus: Selective Photothermolysis Theory
Qhov kev xav no hais txog qhov tseeb tias cov khoom tsim tshwj xeeb thermal zog zog thaum illuminated los ntawm pom lub teeb.Nws cov yam ntxwv tseem ceeb yog tias tsuas yog lub teeb ntawm ib qho xim tuaj yeem nqus tau los ntawm ib qho khoom, thaum lub teeb ntawm lwm cov xim raug cuam tshuam los yog kis tau.
Lub wavelength
Semiconductor laser: Wavelength: 808nm / 810nm ob-mem tes laser tuaj yeem maj mam nce qhov kub ntawm daim tawv nqaij irradiated, maj mam rau ntawm daim tawv nqaij, thiab txhim kho cov plaub hau tshem tawm efficiency tsis ua rau mob thiab lwm yam kev phiv tshwm sim.
Alexandrite laser: Wavelength: 755nm, siab zog.Yog tias lub sijhawm siv dej khov tsis ntev txaus, cov tsos mob tsis zoo xws li erythema thiab hlwv feem ntau tshwm sim.
Lub teeb pom kev zoo: Wavelength: 480nm ~ 1200nm.Qhov luv wavelength yog absorbed los ntawm melanin nyob rau hauv lub epidermis thiab cov plaub hau ncej, dispersing ib feem ntawm lub zog nyob rau saum npoo ntawm daim tawv nqaij, thiab cov seem zog ua rau cov melanin nyob rau hauv lub hauv paus plaub hau.
YAG laser: wavelength: 1064nm.Ib lub wavelength.Lub wavelength yog qhov nkag mus thiab tuaj yeem mloog zoo rau cov plaub hau tob.Nws muaj txiaj ntsig zoo rau cov tawv nqaij tawv, plaub hau thiab daim di ncauj.Daim di ncauj kuj tsim nyog vim hais tias cov plaub hau nyias thiab lub teeb nyob rau hauv cov xim, nrog tsawg melanin nyob rau hauv cov plaub hau follicles thiab lub teeb tsis haum.Cov plaub hau yog tuab heev thiab ntom thiab muaj ntau melanin.
Peb-wavelength lasers yog qhov zoo rau cov cuab yeej tshem tawm cov plaub hau.Kev nqus, nkag mus, thiab kev tiv thaiv yog qhov tseem ceeb thaum siv laser kho kom tshem tawm cov plaub hau.Qhov no laser muab txaus wavelengths rau cov plaub hau tshem tawm.Lub hauv paus ntsiab lus ntawm kev siv peb-wavelength lasers yog "qhov ntau, qhov zoo dua."Kev sib txuas ntawm peb lub wavelengths xav tias yuav tsim cov txiaj ntsig zoo hauv lub sijhawm tsawg dua li ib lub wavelength laser.Triple diode laser technology muab cov kws kho mob nrog kev daws teeb meem thaum siv lasers.Lub laser tshiab no muab qhov zoo ntawm peb qhov sib txawv wavelengths hauv ib lub cuab yeej.Lub handpiece ntawm no laser ntaus ntawv mus txog qhov sib txawv qhov tob nyob rau hauv cov plaub hau follicle.Siv peb qhov sib txawv wavelengths ua ke yuav ua rau muaj txiaj ntsig zoo txog cov kev txwv no.Clinician kev nplij siab thiab kev yooj yim tsis cuam tshuam thaum siv triple-txheej diode lasers rau kev tshem tawm cov plaub hau.Yog li ntawd, peb-wavelength diode laser tuaj yeem yog qhov kev xaiv zoo rau kev tshem tawm cov plaub hau.Qhov no laser tej zaum yuav muaj txiaj ntsig tshwj xeeb rau cov neeg uas muaj tawv nqaij tawv.Nws muaj peev xwm nkag mus tob tshaj plaws thiab ua haujlwm ntawm qhov tob tob xws li tawv taub hau, armpits, thiab qhov chaw mos.Kev ua kom txias hauv cov cuab yeej ua rau cov txheej txheem tshem tawm cov plaub hau yuav luag tsis mob.Tam sim no tus tshiab ntev pulsed 940 nm diode laser siv rau kev tshem tawm cov plaub hau nyob rau hauv Asian hom tawv nqaij.
