Kodi kuchotsa tsitsi la laser ndi chiyani?

Kuchotsa tsitsi la laser pakali pano ndi njira yotetezeka kwambiri, yachangu komanso yokhalitsa yochotsa tsitsi.

mfundo

Kuchotsa tsitsi la laser kumachokera pa mfundo yosankha ma photothermal dynamics.Mwa kusintha moyenerera laser wavelength, mphamvu ndi kugunda m'lifupi, laser akhoza kudutsa pamwamba pa khungu kufika muzu tsitsi follicle.Mphamvu ya kuwala imatengedwa ndikusandulika kukhala mphamvu ya kutentha yomwe imawononga minofu ya tsitsi, kotero kuti tsitsi likhoza kutaya mphamvu yake yokonzanso popanda kuwononga minofu yozungulira, ndipo kupweteka kumakhala kochepa.Kuonjezera apo, kuchotsa tsitsi la laser kumagwiritsa ntchito "elective photothermal effect" ya laser, yomwe imagwiritsa ntchito laser yokonzedwa ndi kutalika kwake kuti idutse pa epidermis ndikuyatsa tsitsi.The melanin wa tsitsi follicle ndi tsitsi shaft mwa kusankha kuyamwa mphamvu kuwala, ndi zotsatira matenthedwe zotsatira kuchititsa tsitsi follicle necrosis ndipo tsitsi silimakulanso.Monga njira ya kutentha mayamwidwe necrosis wa tsitsi follicle ndi zosasinthika, laser kuchotsa tsitsi akhoza kukwaniritsa zotsatira za okhazikika tsitsi kuchotsa.

mwayi

1. Zotsatira za mayeso ambiri azachipatala zikuwonetsa kuti ambiri mwa odwala amangomva "kumenyedwa ndi gulu la rabala".

2. Ubwino wochotsa tsitsi la laser ndikuti tsitsi limachotsedwa kwathunthu.Laser imatha kulowa mkati mwa dermis yakuya ndi minofu yamafuta ochepa, ndikuchitapo kanthu pamitsempha yakuya yamitundu yosiyanasiyana kuti ichotse bwino tsitsi lakuya la gawo lililonse la thupi la munthu.

3. Ubwino wochotsa tsitsi la laser ndikuti sudzawononga epidermis, khungu, ndi thukuta.Ikhoza kuteteza bwino khungu kuti lisawonongeke ndi kutentha.[1]

4. Ubwino wa kuchotsa tsitsi la laser ndikuti mpweya wa pigment pambuyo pochotsa tsitsi uli pafupi kwambiri ndi khungu lathu.

5. Ubwino wa kuchotsa tsitsi laser ndi mofulumira.

Mawonekedwe

1. Utali wabwino kwambiri umagwiritsidwa ntchito pochiza: laser imatha kutengeka bwino mwa kusankha ndi melanin, ndipo laser imatha kulowa bwino pakhungu kuti ifike pamalo amtundu wa tsitsi.Ntchito ya laser ikuwonekera bwino mumbadwo wa kutentha kwa melanin muzitsulo za tsitsi kuchotsa tsitsi.

2. Kuti mukhale ndi zotsatira zabwino kwambiri zochotsera tsitsi, nthawi yofunikira ya laser pulse ikugwirizana ndi makulidwe a tsitsi.Tsitsi lokulirapo, nthawi yayitali ya laser imafunika, yomwe imatha kukwaniritsa bwino popanda kuwononga khungu.

3. Kuchotsa tsitsi la laser sikutulutsa mpweya wa pigment pakhungu pambuyo pochotsa tsitsi ngati njira zachikhalidwe zochotsera tsitsi.Izi ndichifukwa choti khungu limatenga pang'ono laser pakuchotsa tsitsi la laser.

4. Kugwiritsa ntchito makina oziziritsa kungathe kuteteza khungu kuchokera ku laser kuwotcha muzochitika zonse.
