Isikhumba sethuilawulwa amandla amaningi njengoba sikhula: ilanga, isimo sezulu esibi, nemikhuba emibi. Kodwa singathatha izinyathelo zokusiza isikhumba sethu sihlale sithambile futhi sibukeka sisisha.
Ukuthi ubudala besikhumba sakho buzoncika kanjani ezintweni ezihlukahlukene: indlela yakho yokuphila, ukudla, ufuzo, neminye imikhuba yomuntu siqu. Isibonelo, ukubhema kungakhiqiza ama-radicals mahhala, ama-molecule e-oksijini ayenempilo manje asebenza ngokweqile futhi angazinzile. Ama-radicals wamahhala alimaza amangqamuzana, okuholela, phakathi kwezinye izinto, imibimbi ngaphambi kwesikhathi.
Kukhona nezinye izizathu. Izici eziyinhloko ezinomthelela esikhumbeni esishwabene, esinamabala ahlanganisa ukuguga okuvamile, ukuchayeka elangeni (photoaging) nokungcola, nokulahlekelwa ukusekelwa okungaphansi kwesikhumba (izicubu ezinamafutha phakathi kwesikhumba sakho nemisipha). Ezinye izici ezibangela ukuguga kwesikhumba zihlanganisa ukucindezeleka, amandla adonsela phansi, ukunyakaza kobuso nsuku zonke, ukukhuluphala, ngisho nendawo yokulala.
Yiziphi izinhlobo zezinguquko zesikhumba eziza nobudala?
- Njengoba sikhula, izinguquko ezifana nalezi ziyenzeka ngokwemvelo:
- Isikhumba siyaqina.
- Isikhumba siba nezilonda ezinjengamathumba.
- Isikhumba siyaxega. Ukulahlekelwa kwezicubu ezinwebekayo (i-elastin) esikhumbeni ngokukhula kubangela ukuba isikhumba silenga ngokukhululeka.
- Isikhumba siba sobala kakhulu. Lokhu kubangelwa ukuncipha kwe-epidermis (ungqimba olungaphezulu lwesikhumba).
- Isikhumba siba ntekenteke kakhulu. Lokhu kubangelwa ukuncipha kwendawo lapho i-epidermis nedermis (ungqimba lwesikhumba ngaphansi kwe-epidermis) kuhlangana khona.
- Isikhumba siba nemihuzuko kalula. Lokhu kungenxa yezindonga zemithambo yegazi ezacile.
