Kududzirwa chaiko kwemaitiro echisikigo eganda ganda redu rakajairika.Inoperekedzwa nevanhu pakuzvarwa.Iyo inoumbwa neundulating ganda grooves uye ganda crests, ayo anonyanya kugadziriswa mapolygoni uye anenge asina kuchinjika.Kutarisa zvakananga paganda rakashama, unogona kuona maitiro akaoma, akavhiringidzika, pamwe chete nevhudzi rakanaka remavara anorema kana akareruka.Zvisinei, nekufamba kwenguva, vanhu vanoramba vachikwegura, uye ganda rinokurawo zvishoma nezvishoma.Panguva imwecheteyo, ganda rinowanzoonekwa richatamburawo nekunze kwekunze sekusvibiswa kwezvakatipoteredza, uye kuramba kuchikuvadzwa, uye chiyero chekukuvadza kune stratum corneum cells chichachinja.Nhamba yeganda grooves uye mitsetse yeganda iri kuchinja, uye chimiro chakagadzikana chinoratidzikawo chakabatanidzwa, nhamba inoderera, uye nzvimbo yepamusoro inoramba ichiwedzera, saka ganda rinoita kuunyana uye rakaomarara.
Kazhinji, vasati vasvika makore makumi maviri nemashanu, pamusoro peganda rakatsetseka, rinopenya, uye elastic.Mushure meizvi, zvisinei, ganda rinotanga kukwegura zvishoma nezvishoma uye zviratidzo zvepanyama zvinowanzochinja.
1. Unyoro hweganda uye chipingamupinyi cheganda
Zvizhinji zvekutsvagisa pamusoro peganda rakaomarara rinotarisa pamabasa eiyo stratum corneum, senge basa rekugona kuchengetedza mvura uye basa reganda barriers.Zvakadai sekudzidza kwekunyorova, zvakasikwa zvinonyorovesa zvinhu, uye lipid shanduko pakati pe stratum corneum masero.Kurasika kwehunyoro kwakanyanyisa, zvichiita kuti ganda rive matted uye zviyo.Kudeuka kwemasero epidermal kunovhiringidzika, zvichiita kuti pave nekugadzirwa kwedandruff nemakero.Hunyoro hweganda hunoenderana zvakanyanya nehunyoro, kupenya uye kunaka kweganda.Iyo yakatsetseka, ine mvura yakawanda stratum corneum inoratidzira nguva nenguva kuti igadzire kupenya kunopenya, nepo yakaoma, ine scaly stratum corneum inoratidzira nenzira isiri-yakasarudzika inoita kuti ganda riite imvi.Nehunyoro hushoma huri muganda, ganda rinova rakaoma uye rakaoma, uye ganda rinoputika.
Ganda rine basa rakaderedzwa rinodzivisa rakafanana neamburera yakaputsika.Hakusi chete kuti endogenous mvura inoputika nyore nyore, asi kunze kwekukurudzira kuri nyore kupinda, uye kuzvimba kunowanzoitika.Zvakadai sezvinetso zveganda zvine chokuita nekuputika: kuputika, kuputika, kuputika, kuputika, kuputika, nezvimwewo. Zvinetso zveganda zvinogara zvichikonzerwa kwete nemhando yeganda asi nekuputika kusingaperi mukati meganda.
Iyo photoaging epidermis yakaratidza kugadzirisa kukora kana kukuvara kwacho kwakapfava, uye atrophy kana kukuvara kwakanyanya.Masero e-basal layer akachinjwa neatypia yakajeka, uye pakanga pane nhamba yakawanda yemasero e-dyskeratotic.
2. Dermis inorasikirwa nekunaka kwayo
Kushata kweganda kunoenderana zvakanyanya nekutanuka kweganda.Kuwanda kweganda kunoderera, kupfava kweganda kana makwinya kunoonekwa, uye kushata kweganda kunowedzera.Fibroblasts ndiyo inonyanya kukosha cellular chikamu mudermis yeganda uye inoita basa rakakosha mukubatanidzwa kwesecretory fibers uye extracellular matrix.Inoita basa rinokosha mukugadzirisa ronda retishu.Nezera, ukobvu hweganda hunodzikira sezvo elastic fiber yemukati muganda inoderera zvishoma nezvishoma.Kuchembera kweganda kwakakurumbira, izvo zvinogona kuonekwa seganda rakaoma uye rakaomarara, rinowedzera uye rakadzama wrinkles, ganda rakasununguka, uye kuderera kusimba.Zera rinoperekedzwa nekuderera kweganda riri kure neprotein content, kusasimba kwekusimba kweganda, uye kuwedzera kwekudzika kweganda reganda rinotungamirira pakuonekwa kwemakwinya.
Saka matambudziko eganda asati aumbwa, tichine zvinhu zvakawanda zvekuita.Somuenzaniso, theganda analyzerinogona kutibatsira kunonoka kana kugadzirisa matambudziko eganda kune imwe nhanho pamberi peganda matambudziko asati anyatsooneka!
