Intense pulsed light (IPL), yomwe imadziwikanso kuti pulsed strong light, ndi kuwala kotakataka komwe kumapangidwa poyang'ana ndi kusefa gwero lamphamvu kwambiri. Chofunikira chake ndi kuwala wamba kosagwirizana osati laser. Kutalika kwa IPL kumakhala pakati pa 500-1200nm. IPL ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri ndi phototherapy pachipatala ndipo imakhala ndi udindo wofunikira kwambiri pa nkhani ya kukongola kwa khungu. IPL imagwiritsidwa ntchito kwambiri pochiza matenda osiyanasiyana a khungu, makamaka okhudzana ndi photodamage ndi photoaging, zomwe ndi mtundu wa mtundu woyamba wa mtundu woyamba ndi mtundu wachiwiri wotsitsimutsa khungu.
Mtundu Wotsitsimula khungu: Chithandizo cha IPL cha matenda a pigmentary and vascular skin. Matenda a pakhungu monga mawanga, melasma, mawanga a dzuwa, mawanga ngati nevi, ndi zina zotero; Matenda a pakhungu monga telangiectasia, rosacea, erythematous nevi, hemangioma, etc.
Mtundu Wachiwiri wotsitsimula khungu: Ndi mankhwala a IPL a matenda okhudzana ndi kusintha kwa dermal collagen minofu, kuphatikizapo makwinya, ma pores okulirapo, khungu lopakapaka, ndi zipsera zazing'ono zomwe zimasiyidwa ndi matenda osiyanasiyana otupa monga ziphuphu zakumaso ndi nkhuku.
IPL angagwiritsidwe ntchito pochiza photoaging, pigmentary khungu matenda, mitsempha khungu matenda, rosacea, telangiectasia, mawanga, kuchotsa tsitsi, ndi ziphuphu zakumaso.
The chiphunzitso maziko IPL mankhwala a matenda a khungu ndi mfundo ya kusankha photothermal kanthu. Chifukwa cha kuchuluka kwake, IPL imatha kuphimba mitundu ingapo monga melanin, hemoglobin oxidized, madzi, ndi nsonga zina zamayamwidwe.
Pochiza matenda amtima, hemoglobin ndiye chromophore yayikulu. Mphamvu yowunikira ya IPL imatengedwa ndi hemoglobin wokhala ndi okosijeni m'mitsempha yamagazi ndikusinthidwa kukhala mphamvu ya kutentha kuti itenthetse minofu. Pamene kugunda kwa mafunde a kuwala kumakhala kochepa kuposa nthawi yopumula yamtundu womwe mukufuna, kutentha kwa mtsempha wamagazi kumatha kufika pachimake chowononga chotengera chamagazi, chomwe chimatha kuphatikizira ndikuwononga chotengera chamagazi, zomwe zimayambitsa kutsekeka kwa mitsempha ndi kuwonongeka, ndi kusinthidwa pang'onopang'ono ndi minofu ya microscopic kuti akwaniritse cholinga chochizira.
Pochiza matenda amtundu wa pigmentary, melanin imatenga mawonekedwe a IPL ndikupanga "kuphulika kwamkati" kapena "kusankha pyrolysis effect", yomwe imatha kuwononga ma melanocyte ndikuphwanya ma melanosomes.
IPL imapangitsa kuti khungu liziyenda bwino, monga makwinya, makwinya, ndi ma pores okulirapo, makamaka kudzera muzoyambitsa zake zokondoweza. Chithandizo cha ziphuphu zakumaso makamaka chimagwiritsa ntchito photochemical ndi kusankha photothermal zotsatira.
