Laser plaub hau tshem tawm yog dab tsi?

Laser tshem tawm cov plaub hau tam sim no yog qhov kev nyab xeeb tshaj plaws, ceev thiab ntev kev tshem cov plaub hau tshuab.

txoj cai

Laser plaub tshem tawm yog ua raws li lub hauv paus ntsiab lus ntawm kev xaiv photothermal dynamics.Los ntawm kev kho kom zoo ntawm laser wavelength, lub zog thiab mem tes dav, lub laser tuaj yeem hla ntawm daim tawv nqaij kom ncav cuag cov hauv paus plaub hau follicle ntawm cov plaub hau.Lub teeb lub zog yog absorbed thiab hloov mus rau hauv lub tshav kub lub zog uas rhuav tshem cov plaub hau follicle cov ntaub so ntswg, yog li ntawd cov plaub hau yuav poob nws regeneration muaj peev xwm tsis ua puas rau cov ntaub so ntswg nyob ib ncig ntawm, thiab qhov mob yog me ntsis.Tsis tas li ntawd, kev tshem tawm cov plaub hau laser ua rau siv cov "xaiv cov nyhuv photothermal" ntawm laser, uas siv lub laser tuned rau ib lub wavelength tshwj xeeb kom dhau los ntawm epidermis thiab ncaj qha irradiate cov plaub hau follicle.Lub melanin ntawm cov hauv paus plaub hau thiab plaub hau ncej xaiv absorbs lub teeb lub zog, thiab cov nyhuv thermal ua rau cov plaub hau follicle necrosis thiab plaub hau tsis loj hlob.Raws li cov txheej txheem ntawm kev nqus cua sov necrosis ntawm cov hauv paus plaub hau yog irreversible, laser plaub hau tshem tawm tuaj yeem ua tiav cov txiaj ntsig ntawm kev tshem tawm cov plaub hau mus tas li.

qhov zoo

1. Cov txiaj ntsig ntawm ntau qhov kev sim tshuaj qhia tau hais tias feem ntau ntawm cov neeg mob txoj kev xav tsuas yog kev xav ntawm "tso los ntawm cov roj hmab band".

2. Qhov zoo ntawm laser plaub hau tshem tawm yog tias cov plaub hau tshem tawm tag nrho.Lub laser tuaj yeem nkag mus rau hauv qhov sib sib zog nqus dermis thiab cov nqaij rog subcutaneous, thiab ua rau cov plaub hau sib sib zog nqus ntawm qhov sib txawv kom tshem tawm cov plaub hau sib sib zog nqus ntawm txhua qhov ntawm tib neeg lub cev.

3. Qhov zoo ntawm kev tshem tawm cov plaub hau laser yog tias nws yuav tsis ua mob rau cov epidermis, daim tawv nqaij, thiab ua haujlwm tawm hws.Nws tuaj yeem tiv thaiv daim tawv nqaij los ntawm kev puas tsuaj los ntawm tshav kub.[1]

4. Qhov zoo ntawm laser tshem tawm cov plaub hau yog tias cov pigment nag lossis daus tom qab tshem tawm cov plaub hau yog ze rau peb cov tawv nqaij.

5. Qhov zoo ntawm laser tshem tawm cov plaub hau yog ceev.

Nta

1. Qhov zoo tshaj plaws wavelength yog siv rau kev kho mob: lub laser tuaj yeem ua tiav absorbed los ntawm melanin, thiab lub laser tuaj yeem nkag mus rau ntawm daim tawv nqaij kom ncav cuag qhov chaw ntawm cov hauv paus plaub hau.Lub luag hauj lwm ntawm laser yog zoo reflected nyob rau hauv lub tsim ntawm tshav kub ntawm melanin nyob rau hauv cov plaub hau follicles kom tshem tawm cov plaub hau.

2. Rau qhov zoo tshaj plaws kev tshem tawm cov plaub hau, lub sij hawm yuav tsum tau laser mem tes muaj feem xyuam rau lub thickness ntawm cov plaub hau.Lub thicker cov plaub hau, ntev lub sij hawm laser txiav txim yuav tsum tau, uas yuav ua tau lub zoo tagnrho cov nyhuv yam tsis muaj kev puas tsuaj rau daim tawv nqaij.

3. Laser plaub hau tshem tawm tsis tsim pigment nag lossis daus ntawm daim tawv nqaij tom qab tshem tawm cov plaub hau zoo li cov txheej txheem tshem tawm cov plaub hau.Qhov no yog vim hais tias ntawm daim tawv nqaij absorbs tsawg laser thaum lub sij hawm laser tshem tawm cov plaub hau.

4. Kev siv lub tshuab ua kom txias tuaj yeem tiv thaiv cov tawv nqaij los ntawm kev kub hnyiab hauv tag nrho cov txheej txheem.
