Ukuhunyushwa okungokoqobo kwezimpawu ezingokwemvelo zezicubu zesikhumba ukugcwala kwethu kwesikhumba okuvamile. Ihambisana nabantu lapho bezalwa. Ihlanganiswe ngemifino yokukhipha isikhumba kanye nama-crests wesikhumba, ama-polygons ahleliwe kakhulu futhi acishe ashiye. Uma ubheka ngqo esikhunjeni esingenalutho, ungabona ukwakheka okuyinkimbinkimbi, okuxakile, kanye nezinwele ezinhle zombala osindayo noma okhanyayo. Kodwa-ke, ngokuhamba kwesikhathi, abantu bayaqhubeka nokukhula, futhi isikhumba sineminyaka eminingi kancane kancane. Ngasikhathi sinye, isikhumba esivezwa kaningi sizohlushwa yisikhuthazo sangaphandle njengokungcoliswa kwemvelo, bese siqhubeka nokulimala, kanye nezinga lomonakalo kumaseli e-stratum Corneum azoshintsha. Inani lemifino yesikhumba kanye nemithamo yesikhumba iyashintsha, futhi ukwakheka okuzinzile kuvela futhi ku-cross-bonded, inani liyancipha, futhi indawo engaphezulu iyancipha, ngakho-ke indawo engaphezulu iyaqhubeka ukunwetshwa, ngakho-ke isikhumba siba nzima.
Imvamisa, ngaphambi kweminyaka engama-25, ingaphezulu lesikhumba libushelelezi, likhanya, futhi liyakhula. Ngemuva kwaloko, isikhumba siqala ukukhula kancane kancane kanye nezimpawu zomzimba zivame ukuguquka.
1. Umswakama wesikhumba kanye nesithiyo sesikhumba
Iningi labacwaningi ekugxilwe kwesikhumba okunzima emisebenzini yeStratum Corneum, njengokusebenza kwamandla okugcina amanzi kanye nomsebenzi wesithiyo sesikhumba. Njengokutadisha umswakama, izinto ezinomswakama wemvelo, kanye nezinguquko ze-lipid phakathi kwamaseli e-stratum Corneum. Ukulahleka komswakama kunzima, okwenza isikhumba sibe senziwe futhi sinamabele. Ukuchithwa kwamangqamuzana e-epidermal kuphazamisekile, okuholela ekukhiqizweni kwe-dandruff kanye nesikali. Ukuqukethwe komswakama kwesikhumba kuhlobene kakhulu nomswakama, i-luster kanye nesikhumba sesikhumba. I-Corneum ebushelelezi, ethe xaxa ibonisa njalo ukudala imisebe ekhanyayo, ngenkathi i-corneum eyomile, i-scaly stratum corneum ikhombisa ngendlela engeyona ebalulekile eyenza isikhumba sibukeke sibukeke simpunga. Ngokuqukethwe komswakama ophansi esikhunjeni, isikhumba sisomile futhi sikhathele, futhi isikhumba sibuthuntu.
Isikhumba ngomsebenzi wokuvimbela okuncishisiwe ufana nesambulela esiphukile. Akukhona kuphela ukuthi amanzi e-endosous avele kalula avele kalula, kepha okuvuselelayo kwangaphandle kulula ukuhlasela, futhi ukuvuvukala nakho kuthambekele kuye. Ezinjengezinkinga zesikhumba ezihlobene nokuvuvukala: ukulunywa, ukugcotshwa, ukulunywa, ukulunywa, ukubomvu, njll. I-ETC.
I-epidermis ebonakalayo ikhombise ukuqina lapho kufakwa umdlandla, futhi i-atrophy lapho umonakalo unzima. Amaseli wesendlalelo se-basal aguqulwe yi-attypia esobala, futhi kwakukhona inani elikhulu lamaseli we-dyskeratotic.
2. I-dermis ilahlekelwa ukuqina kwayo
Ukuqina kwesikhumba kuhlobene kakhulu nokuqina kwesikhumba. Ukuqina kwesikhumba kuyancipha, kuvela amandla wesikhumba noma imibimbi yensimbi, futhi ukuqina kwesikhumba kuyanda. I-FibroBlasts iyingxenye ebaluleke kakhulu yeselula kwi-dermis yesikhumba futhi idlale indima ebalulekile ekuhlanganiseni kwemicu yokucasha ne-matrix yangaphandle. Idlala indima ebalulekile ekulungiseni izilonda zezicubu. Ngobudala, ukushuba kwesikhumba kuyancipha njengokuqukethwe kwe-tuber in elastic esikhunjeni kancane kancane kuyancipha. Ukuguga kwesikhumba kuvelele, okungabonakala njengesikhumba esomile nesinzima, okwandisiwe futhi kujule imibimbi, isikhumba esivulekile, futhi sehlile ukuqina. Iminyaka ihambisana nokuncipha kwesikhumba okuqukethwe kwe-protein yamaprotheni, ukuntuleka kokuqina esikhunjeni, futhi ukwanda kokujula kokufakwa kwesikhumba okuholela ekubonakaleni kwemibimbi.
Ngakho-ke ngaphambi kokuba kudalwe izinkinga zesikhumba, sisenezinto eziningi okufanele zenziwe. Ngokwesibonelo,Ukuhlaziywa kwesikhumbaKungasisiza ukuthi sinciphise noma sixazulule izinkinga zesikhumba ngezinga elithile ngaphambi kokuba kube nezinkinga zesikhumba ngokuphelele!
