Mu 1998, a FDA adavomereza kugwiritsa ntchito mawuwa kwa ena opanga ma laser ochotsa tsitsi ndi zida zowunikira. Kuchotsa tsitsi la permament sikutanthauza kuchotsedwa kwa tsitsi lonse m'madera ochiritsira.Kuchepetsa kwa nthawi yaitali, kokhazikika kwa chiwerengero cha tsitsi lomwe limakulanso pambuyo pa ulamuliro wa mankhwala.
Mukadziwa mawonekedwe a tsitsi ndi gawo lakukula ndiye Kodi chithandizo cha laser ndi chiyani ndipo chimagwira ntchito bwanji?
Ma laser opangidwira kuchepetsa tsitsi kosatha amatulutsa kuwala komwe kumatengedwa ndi melanin mu folicle ya tsitsi (dermal papilla, matrix cell, melanocytes). Ngati khungu lozungulira limakhala lowala kuposa mtundu wa tsitsi, mphamvu zambiri za laser zidzakhazikika muzitsulo za tsitsi (zosankha photothermalysis), zimawononga bwino popanda kukhudza khungu. Tsitsi likawonongeka, tsitsi limagwa pang'onopang'ono, ndiye kuti zotsalira zakukula kwa tsitsi zimasanduka siteji ya anagen, koma zimasanduka zoonda kwambiri komanso zofewa chifukwa chopanda michere yokwanira yothandizira kukula kwa tsitsi.
Ndi teknoloji iti yomwe ili yoyenera kwambiri kuchotsa tsitsi?
Tradtional mankhwala epilation, mechanical epilation kapena kumeta epilation ndi tweezer onse kudula tsitsi pa epidermis kumapangitsa khungu kuwoneka yosalala koma osakhudza ku folicle tsitsi, ndichifukwa chake tsitsi amakula mofulumira, ngakhale amphamvu kwambiri kuposa kale chifukwa stimulate chifukwa kwambiri tsitsi mu siteji anagen. Kuphatikiza apo, njira zachikhalidwe izi zitha kuvulaza khungu, kutuluka magazi, kukhudzika kwapakhungu ndi zovuta zina. Mungafunse kuti IPL ndi laser zimatenga njira yochizira, bwanji kusankha laser?
Kodi pali kusiyana kotani pakati pa laser ndi IPL?
IPL imayimira 'kuwala kwamphamvu kwambiri' ndipo ili ndi mitundu yosiyanasiyana monga SIPL, VPL, SPL, OPT, SHR yomwe ndiukadaulo womwewo. Makina a IPL si ma lasers chifukwa makina ake amtundu umodzi wavelength.IPL amapanga bandwidth yayikulu ya kutalika komwe kumatha kufika kuya kosiyanasiyana kwa minofu yapakhungu, kutengeka ndi zolinga zosiyanasiyana makamaka monga melanin, hemoglobin, water. mphamvu, chiwopsezo chowotcha pakhungu chidzakhalanso chachikulu kuposa ma semiconductor diode lasers.
General IPL makina ntchito nyali xenon mkati chogwirira chidutswa chimatulutsa kuwala, pali safiro kapena quartz krustalo kutsogolo kukhudza khungu kusamutsa kuwala mphamvu ndi kupanga kuzirala kuteteza khungu.
(kuwala kulikonse kudzakhala kutulutsa kumodzi kuphatikiza ma pulses ambiri), nyali ya xenon (mtundu waku Germany pafupifupi 500000 pulses) nthawi yamoyo idzakhala yocheperako nthawi zambiri kuposa bala ya laser ya diode
(marco-channel kapena micro-channel general from 2 to 20 millions) type.Motero ma lasers ochotsa tsitsi (ie Alexandrite, Diode, ndi ND: Yag mitundu) amakhala ndi moyo wautali komanso kumva bwino kwa chithandizo cha tsitsi losafunikira.Ma lasers awa amagwiritsidwa ntchito mwapadera pa akatswiri ochotsa tsitsi.
