Ukuhumusha ngokwezwi nezwi kwezici zemvelo zezicubu zesikhumba ukuthungwa kwethu okujwayelekile kwesikhumba. Iphelezelwa ngabantu ekuzalweni kwayo. Yakhiwe ngemifantu yesikhumba enyakazayo kanye nezimbotshana zesikhumba, ngokuvamile okungamapholigoni angaguquki futhi acishe angashintshile. Uma ubheka ngqo esikhumbeni esingenalutho, ungabona ukwakheka okuyinkimbinkimbi, okuyisiphithiphithi, kanye nezinwele ezinhle zombala onzima noma okhanyayo. Nokho, ngokuhamba kwesikhathi, abantu bayaqhubeka nokuguga, futhi isikhumba siguga kancane kancane ngokwemvelo. Ngesikhathi esifanayo, isikhumba esivame ukuvezwa sizophinde sihlupheke ngenxa yezizathu zangaphandle ezifana nokungcoliswa kwemvelo, futhi siqhubeke nokulimala, futhi izinga lomonakalo kumaseli we-stratum corneum lizoshintsha. Isibalo semifantu yesikhumba kanye nemigqa yesikhumba siyashintsha, futhi ukumila okuzinzile nakho kubonakala kuxhumene, inombolo iyancipha, futhi indawo engaphezulu iyaqhubeka nokukhula, ngakho isikhumba siyashwabana futhi sibe namaholoholo.
Ngokuvamile, ngaphambi kweminyaka engu-25, ubuso besikhumba bushelelezi, bugqamile futhi bunwebeka. Nokho, ngemva kwalokho, isikhumba siqala ukuguga kancane kancane futhi izimpawu ze-physiological ngokuvamile ziyashintsha.
1. Umswakama wesikhumba kanye nokuvimbela isikhumba
Iningi locwaningo ngesikhumba esimangelengele ligxile emisebenzini ye-stratum corneum, njengomsebenzi wekhono lokugcina amanzi kanye nomsebenzi wokuvimbela isikhumba. Njengokutadisha umswakama, izici zemvelo ezimanzisa, kanye nezinguquko ze-lipid phakathi kwamaseli e-stratum corneum. Ukulahlekelwa umswakama kubi kakhulu, okwenza isikhumba sibe matted futhi sibe nezinhlamvu. Ukuchithwa kwamangqamuzana e-epidermal kuyaphazamiseka, okuholela ekukhiqizweni kwe-dandruff nezikali. Umswakama wesikhumba uhlobene eduze nomswakama, ukucwebezela kanye nokucoleka kwesikhumba. I-stratum corneum ebushelelezi, enamanzi amaningi ibonisa njalo ukuze idale ukukhazimula okukhanyayo, kuyilapho i-corneum eyomile, ene-scaly stratum ibonakala ngendlela engacacile eyenza isikhumba sibukeke simpunga. Ngokuqukethwe komswakama ophansi esikhumbeni, isikhumba siyaba somile futhi sibe lukhuni, futhi isikhumba sibuhlungu.
Isikhumba esinomsebenzi wokuvimbela oncishisiwe sifana nesambulela esiphukile. Akukhona nje ukuthi amanzi e-endogenous ahwamuka kalula, kodwa izisusa zangaphandle kulula ukuhlasela, futhi ukuvuvukala nakho kujwayele ukwenzeka. Njengezinkinga zesikhumba ezihlobene nokuvuvukala: ukulunywa, ukuhwalala, ukuxebuka, ukulunywa, ububomvu, njll. Izinkinga zesikhumba eziphindelelayo ezingabangelwa uhlobo lwesikhumba kodwa ukuvuvukala okungapheli ngaphakathi kwesikhumba.
I-epidermis ye-photoaging ibonise ukulungisa ukujiya lapho umonakalo uncane, kanye ne-atrophy lapho umonakalo mkhulu. Amaseli we-basal layer ashintshwa yi-atypia esobala, futhi kwakukhona inani elikhulu lamaseli e-dyskeratotic.
2. I-dermis ilahlekelwa ukunwebeka kwayo
Ukuqina kwesikhumba kuhlobene eduze nokunwebeka kwesikhumba. Ukunwebeka kwesikhumba kuyehla, ukuxega kwesikhumba noma imibimbi kuvela, futhi ukuqina kwesikhumba kuyanda. I-Fibroblasts iyingxenye yeselula ebaluleke kakhulu ku-dermis yesikhumba futhi idlala indima ebalulekile ekuhlanganiseni imicu eyimfihlo kanye ne-extracellular matrix. Idlala indima ebalulekile ekulungiseni amanxeba ezicubu. Ngokukhula, ukushuba kwesikhumba kuyehla njengoba okuqukethwe kwe-elastic fiber esikhumbeni kuncipha kancane kancane. Ukuguga kwesikhumba kugqamile, okungabonakala njengesikhumba esomile nesiqinile, imibimbi eyandayo futhi ejulile, isikhumba esixegayo, nokuncipha kokunwebeka. Ubudala buhambisana nokuncipha kokuqukethwe kwamaprotheni esikhumbeni, ukuntuleka kokuqina esikhumbeni, nokwanda kokujula kokuthungwa kwesikhumba okuholela ekubonakaleni kwemibimbi.
Ngakho ngaphambi kokuba izinkinga zesikhumba zakheke, sisenezinto eziningi okufanele sizenze. Ngokwesibonelo, iisikhumba analyzeringasisiza ukuba sinciphise ijubane noma sixazulule izinkinga zesikhumba ngezinga elithile ngaphambi kokuba izinkinga zesikhumba zivele ngokugcwele!
