Ukuhumusha ngokoqobo kwezici ezingokwemvelo zezicubu zesikhumba ukuthungwa kwesikhumba okuvamile. Kuhambisana nabantu lapho bezalwa. Kwakhiwe imifantu yesikhumba egobile kanye nezinsika zesikhumba, okuvame ukuba ngama-polygon aqinile futhi cishe angashintshi. Uma ubheka ngqo isikhumba esingenalutho, ungabona ukuthungwa okuyinkimbinkimbi, okuxakile, kanye nezinwele ezincane ezinombala osindayo noma okhanyayo. Kodwa-ke, ngokuhamba kwesikhathi, abantu bayaqhubeka nokuguga, kanti isikhumba naso siyaguga kancane kancane ngokwemvelo. Ngesikhathi esifanayo, isikhumba esivame ukudalulwa sizohlushwa yizinto zangaphandle ezifana nokungcola kwemvelo, futhi siqhubeke nokulimala, futhi izinga lomonakalo kumaseli e-stratum corneum lizoshintsha. Inani lemifantu yesikhumba kanye nezinsika zesikhumba liyashintsha, futhi isimo esizinzile sibonakala sixhumene, inani liyancipha, futhi indawo engaphezulu iyaqhubeka nokukhula, ngakho isikhumba siba nemibimbi futhi siqinile.
Ngokuvamile, ngaphambi kokuba umuntu abe neminyaka engu-25 ubudala, ubuso besikhumba bubushelelezi, bukhanya, futhi buyanwebeka. Nokho, ngemva kwalokho, isikhumba siqala ukuguga kancane kancane futhi izimpawu zomzimba zivame ukushintsha.
1. Umswakama wesikhumba kanye nesithiyo sesikhumba
Iningi locwaningo ngesikhumba esiqinile lugxile emisebenzini ye-stratum corneum, njengomsebenzi wamandla okugcina amanzi kanye nomsebenzi wokuvimbela isikhumba. Njengokufunda ngomswakama, izinto zemvelo zokuthambisa, kanye noshintsho lwamafutha phakathi kwamaseli e-stratum corneum. Ukulahleka komswakama kukhulu, okwenza isikhumba sibe matte futhi sibe grey. Ukuchitheka kwamaseli e-epidermal kuyaphazamiseka, okuholela ekukhiqizweni kwe-dandruff kanye nezikali. Okuqukethwe komswakama kwesikhumba kuhlobene eduze nomswakama, ukukhanya kanye nobuncane besikhumba. I-stratum corneum ebushelelezi, enamanzi kakhulu ikhanya njalo ukudala ukukhanya okukhanyayo, kuyilapho i-stratum corneum eyomile, enamaqhubu ikhanya ngendlela engeyona eyingqayizivele eyenza isikhumba sibukeke simpunga. Ngokuqukethwe komswakama okuphansi esikhumbeni, isikhumba siba somile futhi siqinile, futhi isikhumba siba buthuntu.
Isikhumba esinomsebenzi onciphile wokuvimbela sifana nesambulela esiphukile. Akukhona nje kuphela ukuthi amanzi angokwemvelo ayanyamalala kalula, kodwa futhi kulula ukuhlasela izinto zangaphandle, futhi ukuvuvukala nakho kuvame ukwenzeka. Njengezinkinga zesikhumba ezihlobene nokuvuvukala: ukulunywa, ukuklwebheka, ukuxebuka, ukulunywa, ukubomvu, njll. Izinkinga zesikhumba eziphindaphindayo ezibangelwa hhayi uhlobo lwesikhumba kodwa ukuvuvukala okungapheli ngaphakathi kwesikhumba.
I-epidermis ehlala ibukeka ibukeka iqine uma umonakalo ulula, kanye ne-atrophy uma umonakalo unzima. Amaseli engqimba engezansi ashintshwa yi-atypia esobala, futhi kwakukhona inani elikhulu lamaseli e-dyskeratotic.
2. I-dermis ilahlekelwa ukunwebeka kwayo
Ukugoba kwesikhumba kuhlobene kakhulu nokugoba kwesikhumba. Ukugoba kwesikhumba kuyancipha, kuvela ukugoba kwesikhumba noma imibimbi, futhi ukugoba kwesikhumba kuyanda. Ama-Fibroblast ayisici esibaluleke kakhulu samaseli esikhumbeni futhi adlala indima ebalulekile ekwakhiweni kwemicu ekhipha uketshezi kanye ne-extracellular matrix. Adlala indima ebalulekile ekulungisweni kwamanxeba ezicubu. Njengoba ukhula, ukujiya kwesikhumba kwehla njengoba okuqukethwe kwe-elastic fiber esikhumbeni kuncipha kancane kancane. Ukuguga kwesikhumba kuyabonakala, okungabonakala njengesikhumba esomile nesinamaqhubu, imibimbi eyandayo nejulile, isikhumba esikhululekile, kanye nokugoba okunciphile. Ubudala buhambisana nokwehla kokuqukethwe kwamaprotheni esikhumba, ukuntuleka kokuqina esikhumbeni, kanye nokwanda kokujula kokuthungwa kwesikhumba okuholela ekubukekeni kwemibimbi.
Ngakho-ke ngaphambi kokuba izinkinga zesikhumba zivele, sisenezinto eziningi okufanele sizenze. Isibonelo,isihlaziyi sesikhumbakungasisiza ukuthi sehlise ijubane noma sixazulule izinkinga zesikhumba ngezinga elithile ngaphambi kokuba izinkinga zesikhumba zibonakale ngokugcwele!
