Mu 1998, bungwe la FDA linavomereza kugwiritsa ntchito mawuwa kwa opanga ena opanga ma laser ochotsa tsitsi ndi zida zowunikira. Kuchotsa tsitsi kosatha sikutanthauza kuchotsa tsitsi lonse m'malo ochiritsira. Kuchepetsa kwa nthawi yayitali komanso kokhazikika kwa chiwerengero cha tsitsi lomwe limakulanso pambuyo pa chithandizo.
Mukadziwa kapangidwe ka tsitsi ndi kukula kwake, kodi laser therapy ndi chiyani ndipo imagwira ntchito bwanji?
Ma laser opangidwa kuti achepetse tsitsi nthawi zonse amatulutsa kuwala komwe kumayamwa ndi melanin mu folicle ya tsitsi (dermal papilla, matrix cell, melanocytes). Ngati khungu lozungulira ndi lopepuka kuposa mtundu wa tsitsi, mphamvu zambiri za laser zimayikidwa mu shaft ya tsitsi (selective photothermalysis), ndikuwononga bwino popanda kukhudza khungu. Tsitsi likawonongeka, tsitsi lidzagwa pang'onopang'ono, ndiye kuti ntchito yotsala yokulitsa tsitsi idzasanduka gawo la anagen, koma idzasanduka yopyapyala komanso yofewa chifukwa chosowa michere yokwanira yothandizira kukula kwa tsitsi.
Ndi ukadaulo uti woyenera kwambiri pochotsa tsitsi?
Kudula tsitsi pogwiritsa ntchito mankhwala achikhalidwe, kudula tsitsi pogwiritsa ntchito makina kapena kumeta pogwiritsa ntchito tweezer kumapangitsa kuti khungu lizioneka losalala koma silimakhudza tsitsi, ndichifukwa chake tsitsi limakula mofulumira, komanso lolimba kwambiri kuposa kale chifukwa cha kukondoweza komwe kumayambitsa tsitsi kulowa mu gawo la anagen. Kuphatikiza apo, njira zachikhalidwe izi zingayambitse kupweteka kwa khungu, kutuluka magazi, kumva khungu ndi mavuto ena. Mungafunse kuti IPL ndi laser zimagwiritsa ntchito njira yofanana yochizira, bwanji osasankha laser?
Kodi kusiyana pakati pa laser ndi ipl ndi kotani?
IPL imayimira 'intense pulsed light' ndipo ili ndi mitundu yosiyanasiyana monga SIPL, VPL, SPL, OPT, SHR zomwe zonse ndi ukadaulo womwewo. Makina a IPL si ma laser chifukwa si ma wavelength amodzi. Makina a IPL amapanga bandwidth yayikulu ya ma wavelength yomwe imatha kufikira kuzama kosiyana kwa minofu ya khungu, yomwe imayamwa ndi zolinga zosiyanasiyana kuphatikizapo melanin, hemoglobin, ndi madzi. Chifukwa chake imatha kutentha minofu yonse yozungulira kufikira zotsatira zambiri monga kuchotsa tsitsi ndi kukonzanso khungu, kuchotsa mitsempha yamagazi, chithandizo cha ziphuphu. Koma chithandizo chokhala ndi kupweteka chifukwa cha mphamvu yake yayikulu ya kuwala kwa broad spectrum, chiopsezo cha kutentha pakhungu chidzakhala chachikulu kuposa ma semiconductor diode lasers.
Makina a IPL amagwiritsa ntchito nyali ya xenon mkati mwa chogwiriracho, yomwe imatulutsa kuwala, pali kristalo wa safiro kapena quartz kutsogolo, zomwe zimapangitsa kuti khungu lizitha kuzizira ndikuzimitsa kuti khungu lizitetezedwe.
(kuwala kulikonse kudzakhala kotulutsa kamodzi kuphatikiza ma pulse ambiri), nyali ya xenon (yabwino kwambiri ku Germany pafupifupi ma pulse 500000) nthawi yonse ya moyo idzakhala yocheperako kuposa bala ya laser ya diode laser.
(mtundu wa marco-channel kapena micro-channel general kuyambira 2 mpaka 20 miliyoni). Chifukwa chake ma laser ochotsa tsitsi (monga Alexandrite, Diode, ndi ND:Yag) nthawi zambiri amakhala ndi moyo wautali komanso womasuka kwambiri pochiza tsitsi losafunikira. Ma laser awa amagwiritsidwa ntchito makamaka ku malo ochotsera tsitsi akatswiri.
