Red Light Therapy (RLT) ingathandize pochiza Post-inflammatory Hyperpigmentation (PIH). Hyperpigmentation nthawi zambiri imachitika kutupa kapena kuvulala kwa khungu kutatha, nthawi zambiri chifukwa ma melanocyte pakhungu akupanga melanin yambiri.
Red Light Therapy imalowa m'magawo akuya a khungu ndi kutalika kwake kwa kuwala (nthawi zambiri 630-650 nanometers) kuti ilimbikitse njira yokonzanso maselo a khungu, kusintha kuyenda kwa magazi ndikuwonjezera kupanga collagen. Imachepetsanso kutupa kwa khungu ndikulimbikitsa kuchira kwa khungu. Zotsatirazi zimathandiza kuchepetsa kuwoneka kwa hyperpigmentation, makamaka kusintha kwa mtundu komwe kumachitika chifukwa cha hyperpigmentation pambuyo pa kutupa.
Kutupa kwa khungu pambuyo pa kutupa (PIH) ndi kuchuluka kwa melanin yochulukirapo pakhungu pambuyo pochira matenda kapena kuvulala kwa khungu, komwe kungayambitse mdima pakhungu kapena kusintha mtundu wake. Nthawi zambiri zimachitika khungu likayamba kutupa, monga ziphuphu, eczema, kuchira kwa mabala, kupsa ndi dzuwa, kapena kuyabwa kwina pakhungu.
Kodi hyperpigmentation pambuyo pa kutupa ndi chiyani?
Zomwe zimayambitsa mapangidwe a hyperpigmentation pambuyo pa kutupa:
1. Kutupa: Pakachitika kutupa pakhungu, maselo a khungu (makamaka ma melanocyte) amayamba kugwira ntchito kuti apange melanin yambiri. Kupezeka kwa kutupa kumalimbikitsa ma melanocyte kuti apange melanin yambiri.
2. Kuvulala Pakhungu: Kuvulala kulikonse pakhungu, kuphatikizapo ziphuphu, kupsa kapena mabala, kungayambitse kutayika kwa melanin m'malo osiyanasiyana. Izi zili choncho chifukwa panthawi yochira, khungu limakonzedwanso, ndipo melanin yowonjezera ikhoza kupangidwa panthawiyi.
3. Kuwonekera kwa UV: Kuwonekera kwa UV kungapangitse kuti khungu lizikula kwambiri, makamaka m'malo omwe khungu lawo lawonongeka kale, ndipo kuwala kwa UV kungayambitse kupanga melanin, zomwe zimapangitsa kuti khungu lizikula kwambiri.
Makhalidwe:
Kusaoneka ndi mtundu kapena khungu losafanana: Kawirikawiri limapezeka ngati mawanga akuda kapena abulauni pakhungu, nthawi zambiri akuda kuposa mtundu wa khungu lozungulira.
Kufalikira Kosasinthasintha: Utoto nthawi zambiri umapezeka pafupi ndi malo omwe kutupa koyambirira kumachitika ndipo ukhoza kuwonekera pankhope, pachifuwa, kumbuyo, mapewa kapena miyendo.
Kodi hyperpigmentation ndi chilonda?
Mawanga akuda omwe amayamba chifukwa cha kuchuluka kwa pigmentation pambuyo pa kutupa nthawi zambiri amasokonezedwa ndi zipsera; komabe, mawanga akuda awa ndi osiyana kwambiri ndi zipsera. Pamene dermis, kapena zigawo zakuya za khungu, zawonongeka, collagen matrix pakhungu imadzikonza yokha mosakhazikika, ndikusiya zizindikiro zokhalitsa pathupi. Zipsera nthawi zambiri zimakwezedwa (hypertrophic) kapena kuchepetsedwa (dystrophic), pomwe mawanga akuda omwe amayamba chifukwa cha kuchuluka kwa pigmentation pambuyo pa kutupa amakhala athyathyathya pakhungu. Kuphatikiza apo, zipsera zambiri zimawoneka zopepuka kuposa mtundu wa khungu, koma izi sizofala.
Ngakhale kuti hyperpigmentation imadziziritsa yokha pambuyo pa kutupa, ngakhale izi zingatenge nthawi, zipsera zimakhala zokhalitsa. M'malo omwe ali ndi hyperpigmentation, khungu la khungu silimawonongeka kwenikweni ndipo melanin yochulukirapo ndi gawo la njira yochiritsira. Ganizirani za momwe khungu limayankhira ku UV (kuwala kwa dzuwa): melanin imapangidwa kuti idetse khungu ndikuliteteza ku kuwonongeka kwa UV, chifukwa mithunzi yakuda imayamwa kuwala kochepa. Pankhani ya hyperpigmentation pambuyo pa kutupa, melanin yochulukirapo imaletsa kuwonongeka kwina kwa UV.
Chithandizo cha hyperpigmentation pambuyo pa kutupa
Ngakhale kuti khungu likayamba kuuma kwambiri, mawanga akuda omwe amauma amatha kukhala okwiyitsa kapena osavomerezeka. Komabe, pali zinthu zambiri zomwe zingathandize kuchotsa mawanga akuda. Chithandizo chodziwika bwino cha mawanga akuda ndi kugwiritsa ntchito retinol, chomwe chimapezeka mu mafuta ambiri ndi seramu, chomwe chimawonjezera kupanga kwa collagen ndi kukonzanso maselo. Anthu ambiri omwe amagwiritsa ntchito zinthu za retinol amakumana ndi kufiira ndi kupukuta khungu, zomwe ndi chizindikiro cha kukwiya ndi mankhwalawa komanso chifukwa chomwe anthu ena amasiya kulandira mankhwala a retinol. Zinthuzi ndizokwera mtengo kwambiri ndipo zimatha kutenga masiku 90 kuti ziyambe kuwonetsa zotsatira.
Momwe Kuchiritsa kwa Red Light Kumathandizira Kuchuluka kwa Pigmentation
Chithandizo cha kuwala kofiira chimathandiza pamavuto osiyanasiyana a pakhungu kuphatikizapo ziphuphu, makwinya, zipsera ndi kuwonongeka kwa dzuwa. Chithandizochi chimagwiritsa ntchito kuwala kofiira kochulukira kuti chilimbikitse kupanga mphamvu zamaselo, zomwe zimapangitsa kuti pakhale zochitika zosiyanasiyana kuti machiritso achilengedwe apitirire. Kuchuluka kwa magazi m'thupi kumathandiza kupereka mankhwala ophera kutupa ku minofu yowonongeka kuti achepetse kutupa mwachangu. Kuphatikiza apo, chithandizo cha kuwala kofiira chimawonjezera kupanga kwa collagen, gawo lalikulu la maselo a khungu lathu omwe amathandiza kusunga kapangidwe ndi kusinthasintha.
Tonsefe tili ndi khungu losiyana, kotero ndikofunikira kuti chithandizo cha khungu chikhale chosiyanasiyana komanso chosinthidwa. Chithandizo cha kuwala kofiira chikhoza kusinthidwa kwa munthu aliyense, pogwiritsa ntchito mitundu yosiyanasiyana ya mafunde, mphamvu, komanso kugwiritsa ntchito kuwala kosalekeza kapena kozungulira. Kuphatikiza apo, mabedi owala (mongaBedi la ku America lotchedwa Red Light Therapy Bed m4n) akhoza kuchiza thupi lonse nthawi imodzi. Izi zikutanthauza kuti mungathe kuthetsa madera angapo a zofooka pakhungu nthawi imodzi.
Chithandizo cha kuwala kofiira ndi chithandizo chosavulaza chomwe sichimayambitsa kuyabwa ndi kutsekeka komwe anthu ambiri amakumana nako pogwiritsa ntchito mankhwala a retinoid. Kuphatikiza apo, anthu ambiri amayamba kuwona zotsatira mkati mwa milungu ingapo yoyambirira ya chithandizo.
