I-Intense pulsed light (IPL), ekwabizwa ngokuba yi-pulsed strong light, kukukhanya okubanzi okwenziwa ngokujolisa nokucoca umthombo wokukhanya ophezulu. Undoqo wayo awuhambelani nokukhanya okuqhelekileyo kune-laser. Ubude bobude be-IPL ubukhulu becala buphakathi kwe-500-1200nm. I-IPL yenye yezona ndlela zisetyenziswa kakhulu kwi-phototherapy yobuchule kwiklinikhi kwaye ibambe indawo ebaluleke kakhulu kwinkalo yobuhle bolusu. I-IPL isetyenziswa ngokubanzi kunyango lwezifo zesikhumba ezahlukahlukeneyo, ngakumbi ezo zihambelana ne-photodamage kunye ne-photoaging, ezizezi Uhlobo lwe-Classic Type I kunye nohlobo lwe-II yokuvuselela ulusu.
Uhlobo lwe-I ukuvuselelwa kwesikhumba: unyango lwe-IPL lwe-pigmentary kunye nezifo zesikhumba ze-vascular. Izifo zesikhumba ezinemibala ziquka amabala, i-melasma, amabala elanga, amabala abomvu njenge-nevi, njl. Izifo zesikhumba se-Vascular, kuquka i-telangiectasia, i-rosacea, i-erythematous nevi, i-hemangioma, njl.
Uhlobo lwe-II yokuvuselela ulusu: Lunyango lwe-IPL lwezifo ezinxulumene notshintsho kwisakhiwo se-dermal collagen tissue, kubandakanywa imibimbi, i-pores eyandisiweyo, ulusu olubi, kunye nezibazi ezincinci ze-concave ezishiywe zizifo ezahlukahlukeneyo ezivuthayo ezifana ne-acne kunye nenkukhu.
I-IPL ingasetyenziselwa ukunyanga i-photoaging, izifo zesikhumba ze-pigmentary, izifo zesikhumba se-vascular, i-rosacea, i-telangiectasia, i-freckles, ukususwa kweenwele, kunye ne-acne.
Isiseko sethiyori sonyango lwe-IPL yezifo zesikhumba ngumgaqo wokukhetha isenzo se-photothermal. Ngenxa yobubanzi bayo, i-IPL inokugquma iziseko zombala ezininzi ezifana ne-melanin, i-hemoglobin ene-oxidized, amanzi, kunye nezinye iincopho zokufunxa.
Xa unyango lwezifo zesikhumba se-vascular, i-hemoglobin iyona chromophore ephambili. Amandla okukhanya e-IPL afunxwa ngokukhethekileyo yi-oksijini ye-hemoglobin kwimithambo yegazi kwaye iguqulelwe amandla obushushu ukutshisa izicubu. Xa ububanzi be-pulse ye-wave yokukhanya bungaphantsi kwexesha lokuphumla kwe-thermal ye-tissue ekujoliswe kuyo, ubushushu bomkhumbi wegazi bunokufikelela kumda womonakalo wesitya segazi, esinokuthi sidibanise kwaye sitshabalalise isitya segazi, esikhokelela kwi-vascular occlusion kunye nokuwohloka, kwaye ngokuthe ngcembe itshintshwe ngezicubu ezincinci ukuze ufezekise injongo yonyango.
Xa unyanga izifo zolusu lwe-pigmentary, i-melanin ithatha ngokukhethiweyo i-IPL kwaye ivelise "isiphumo sokuqhuma kwangaphakathi" okanye "isiphumo esikhethiweyo se-pyrolysis", esinokutshabalalisa i-melanocytes kunye ne-melanosomes ephukile.
I-IPL iphucula imeko yolusu enje ngokuhexa, imibimbi, kunye neepores ezandisiweyo, ngakumbi ngesiphumo sokuvuselela ibhayoloji. Unyango lwe-acne lusebenzisa i-photochemical kunye nemiphumo ekhethiweyo ye-photothermal.
