Kukuvadzwa kweganda hakungogumiri pakuderedza mvura mumuviri, kuoma uye kuvaviwa, asiwo kunowanzo kukonzera matambudziko akasiyana-siyana eganda akadai seganda rinonzwa kurwadziwa, mapundu, dermatitis, psoriasis, nezvimwewo. Kuwedzera kune mishonga yemuviri uye yemudumbu, kurapwa nemwenje mutsvuku we LED, uko kune zvakanakira zvekuti hakukuvadzi, hakurwadzi uye hakuiti kuti munhu apore, kwakakurumbira muDhipatimendi reDermatology.
Zvidzidzo zvekare zvekiriniki zvakawana kuti kupiswa kwechiedza chitsvuku kunogona kuderedza mwero wekurasikirwa kwemvura kubva paganda, kuwedzera kunyorova kwe stratum corneum, kudzivirira kuumbwa kwe melanin uye kuchengetedza kubatana kwakasimba kwe collagen fibers, izvo zvinovandudza zvakanyanya chitarisiko uye mashandiro ekudzivirira ganda.
Mwenje mutsvuku unogadzirisa sei chivhariso cheganda?
Kuratidzwa nechiedza chitsvuku kunoderedza kurasikirwa nemvura inoyerera paganda
Tsvagiridzo inoratidza kuti kupenya kwechiedza chitsvuku kunogona kukurudzira kuwanda nekusiyana kwekeratinocytes, zvichiita kuti masero e stratum corneum arongwe zvakasimba, uye panguva imwe chete kukurudzira kugadzirwa kwemafuta ari pakati pemasero akadai se ceramides, fatty acids, nezvimwewo. Mafuta aya anogona kushandiswa ne epidermis kugadzira firimu remafuta rinoramba richiyerera mumvura. Mafuta aya anogona kuzadza pakati pemasero kugadzira firimu remafuta rinoramba richiyerera mumvura. Mafuta aya anogona kuzadza masero e stratum corneum kugadzira firimu remafuta rinoramba richiyerera mumvura, seganda rinoisa "zvipfeko zvisingapindi mvura", zvichidzivirira kupararira kwemvura kubva paganda kuenda kunzvimbo yekunze, nokudaro zvichideredza kurasikirwa kwemvura inoyerera mumvura.
Muongororo yehuwandu hweganda rinonzwa, mwero wekurasikirwa nemvura kubva muganda usati wapiswa nemwaranzi, pakarepo mushure mekupiswa nemwaranzi uye awa imwe mushure mekupiswa wakaratidza kudzikira zvishoma nezvishoma nekuwedzera kwemazuva ekupiswa nemwaranzi. Zvakabuda zvinoratidza kuti chiedza chitsvuku che640 nm chinobatsira kuchengetedza ganda, kuderedza kurasikirwa nemvura uye kuchengetedza ganda rakanyorova.
Kupiswa kwechiedza chitsvuku kunogona kuchengetedza mvura mu stratum corneum
Ongororo dzakakosha dzakaratidza kuti chiedza chitsvuku chinoshanda pamitochondria yemasero eganda, zvichikonzera maitiro akasiyana-siyana ekuchinja kwemasero mumuviri, zvichiwedzera mashandiro emasero, zvichiagonesa kugadzira nekuburitsa zvinhu zvinonyorovesa zvakaita se hyaluronic acid, lactate, urea, nezvimwewo zvinobudirira. Zvinhu izvi zvinogona kunwisa mvura kubva mudermis nenzvimbo yekunze, nokudaro zvichichengetedza huwandu hwakawanda hwemvura uye hunyoro.
Zvakakosha kutaura kuti kuchengetwa kweganda zvakanaka uye zvinobudirira mushure mekupiswa nemwaranzi yechiedza chitsvuku kunobatsira ganda kuti ridzoke uye kunovandudza mamiriro eganda rose pamwe nemhedzisiro yekurapa kwacho.
Kupenya kwechiedza chitsvuku kunodzivirira kuumbwa kwemelanin. Ongororo dzakawanda dzakawana kuti kupenya kwechiedza chitsvuku kunokonzera shanduko mukuratidzwa kwemamorekuru ekuzivisa ane chekuita nebasa retyrosinase mumamelanocytes, zvichikonzera kudziviswa kwebasa retyrosinase, nokudaro zvichideredza kugadzirwa kwemelanin uye kuchengetedza hutano hweganda.
Panguva imwe chete, chiedza chitsvuku chine simba rekudzivirira muviri, chinogona kukurudzira mashandiro ema enzymes ekudzivirira muviri, akadai se superoxide dismutase, glutathione peroxidase, nezvimwewo, kuderedza huwandu hweROS yemukati memasero, izvo zvinoderedza mhedzisiro yekusimudzirwa kwekushushikana kwe oxidative pakugadzirwa kwe melanin, zvichibatsira kuderedza kuunganidzwa kwe hyperpigmentation, kuderedza kukuvara kwekuzvimba.
Kuvhenekerwa kwechiedza chitsvuku kunogona kukurudzira kugadzirwa kwecollagen itsva. Zvidzidzo zvakawanda zvekiriniki nedata zvakasimbisa kuti kuvhenekerwa kwechiedza chitsvuku che LED kunogona kukurudzira kuwanda nekutama kwefibroblasts, kukurudzira kuora kwefibers dzakaputsika uye collagen yakakanganisika mudermis, nokudaro zvichikurudzira kugadzirwa kwecollagen itsva, zvichiita kuti dermal collagen fibers ienderane zvakanaka uye zvakasimba uye zvichiwedzera zvakanyanya kuwanda kwayo, zvichiratidza kuvandudzika kwemakwinya eganda, kusimba uye zvimwe zvinodzivirira zvinoderedza kukwegura kweganda.
Muchidzidzo chekurapa varwere vane mavanga ekutambanudza, mhedzisiro yekuyedza yakaratidzawo kuti kupenya kwechiedza chitsvuku kunogona kuwedzera zvakanyanya kuratidzwa kweTGF-β mu dermal fibroblasts yemunhu, uye panguva imwe chete kuwedzera kuratidzwa kwemajini e collagen, izvo zvinokurudzira kugadzirwa kwe collagen uye zvinoita kuti mavanga ekutambanudza apere zvishoma nezvishoma.
Kamuri rekuchenesesa reMERICAN rinochengetedza ganda
Kuwedzera pane zvataurwa pamusoro apa, zvidzidzo zvekiriniki nedata mune dzimwe nzvimbo dzakati wandei dzakaratidza zvizere kuchengetedzeka uye kushanda kwechiedza chitsvuku pakugadzirisa ganda. Chinonyanya kukosha ndechekuti, kurapwa nechiedza chitsvuku che LED se tekinoroji yekushongedza kwakatenderwa uye kwakabvumidzwa neUS Food and Drug Administration (FDA).
Zvichibva pakurapa nechiedza chitsvuku, kabhini yekuchenesesa yechizvarwa chechitatu yeMERICAN inobatanidza tekinoroji ye multi-ratio composite light source yakagadzirwa pamwe chete neMERICAN nechikwata cheGerman. Kuburikidza nemwaranzi yemuviri wese, inogona kumutsa mabasa e mitochondria nema enzymes kuti ipe simba rakakwana uye hwaro hwezvinhu zve metabolism yemasero eganda, izvo zvinogona kubatsira kukurudzira kugadzirwa kwe collagen, kuderedza kukuvara kwekuzvimba uye melanin, uye kuita kuti ganda risagadzikane, zvichiita kuti ganda rive jena uye kusimbisa ganda.
Kukuvadzwa kweganda hakungokanganisi runako rweganda chete, asiwo hutano hwaro. Kana uchida kuva neganda rakanaka uye rine hutano uye kunonoka kukwegura, unogona kutanga nekudzivirira nekugadzirisa ganda.
