Isikhumba, njengoba kuyaziwa, yilona isakhi esikhulu somzimba womuntu. Ihlanganisa imisebenzi eminingi:
- ukuvikela;
- ukuphefumula;
- ukushisa ukushisa;
- i-tactile;
- Ukuhlanza;
- ukuvuselela.
Ngakho-ke akumangalisi ukuthi isikhumba singathinta ithonya elibi lemvelo futhi sibonise izimpawu zokungathokozi kwangaphakathi komzimba. Enye yalezi zibonakaliso kungase kube ukwephulwa kwesikhumba sokukhumba isikhumba.
Izimbangela zePigmentation lesikhumba
Umehluko embala wesikhumba uncike ekuhlanganiseni kwezakhi eziningana:
- i-melanin;
- i-oxyhemoglobin;
- i-hemoglobin encishisiwe;
- i-carotene.
Kodwa indima eyinhloko ekuhloliseni izinwele, isikhumba namehlo kungokwe-melanin. Futhi ukwephulwa kwesikhumba sokuhlanzwa kwesikhumba kuchazwa ngokunciphisa noma ukwandisa okuqukethwe kwe-melanin emzimbeni.
Ukubonakaliswa kokuncipha kwe-pigmentation kungahle kube kanje:
- i-albinism (ukungabi khona kwe-terezone ye-enzyme, kanye nokuphumela kokungahambisani kahle kwe-melanin);
- i-vitiligo (ukulimala kwamasosha omzimba, mhlawumbe ifa).
Ukwandiswa kokuqukethwe kwe-melanin kubonakala njenge:
- i-freckles (inani labo landa ngesikhathi sonyaka esifudumele futhi idlula ngokuqala kwekwindla);
- ukwakheka kwe-chloasma (izindawo ezibomvu, ngokuvamile ezitholakala nge-symmetrically ebusweni)
- inombolo enkulu yezikhumbuzo zokubeletha kanye nezindawo zokubeletha;
- ukubonakala kwamachashazi phambi kwezinkinga ze-dermatological (ama-acne, ukulunywa kwezinambuzane, amanxeba),
- imiphumela emibi uma uthatha imithi noma ukuvimbela imithi);
- ukutholakala kwe-melanoma.
Kuzo zonke izimo, ukuphazanyiswa kokukhiqizwa kwe-melanin kungabangelwa izinguquko ezihlobene nobudala emzimbeni.
Indawo engama-pigmented
Ukulahlekelwa kwesikhumba sokushisa isikhumba, kanye nokwanda kwe-pigmentation, kungaba kunoma iyiphi ingxenye yesikhumba. Njengomthetho, ubuso nezandla zithinteka kakhulu. Lokhu kungenxa yokuthi lezi zingxenye zomzimba zitholakala kakhulu ekukhanyeni kwelanga, futhi imisebe ye-ultraviolet ingabangela ukuphazamiseka kwe-pigment. Ukwephulwa kwe-pigmentation esikhumba emilenzeni kufanele uqaphe futhi kube yisikhathi sokuvakashela udokotela, tk. Kusemilenzeni kaningi kunezibonakaliso zama-lichen kanye nezimpawu zomdlavuza wesikhumba.
Ukwelashwa kwezifo zesikhumba se-pigmentation
Into yokuqala okufanele uyenze uma ubona ukwephulwa kwesikhumba sokugaya isikhumba ukuvakashela i-dermatologist. Uma lezi ziphazamiso zibangelwa ukuchayeka ngokweqile ekukhanyeni kwe-ultraviolet noma izinguquko ezihlobene nobudala, ukuvakashelwa okulandelayo ku-cosmetologist, okuzokhetha izinqubo ezifanele (ukucubungula, ukulimala, ukunakekelwa kwesikhumba, ukhilimu wokunakekelwa kwesikhumba) kuzokusiza.
Uma ukubukeka kwamachashazi ahlotshisiwe kubangelwa ukuphulwa kwemisebenzi yelungu langaphakathi, bese ukwelashwa okulungile futhi okufika ngesikhathi ngudokotela ochwepheshe kuzokwenza kube lula ukuqeda lesi sibonakaliso esingathandeki.
Ukususa ama-moles ku-90% kuyinkqubo ephephile. Kodwa uma ubona ushintsho ngohlobo noma usayizi we-birthmark, kufanele uthintane nochwepheshe, njengoba lokhu kungase kube uphawu lokuwohloka okubi.
Indlela yokunciphisa ukubonakaliswa kokuguqulwa kwesithombe?
Ukuze unciphise ukubonakaliswa kwezifo zesikhumba somzimba, umuntu kufanele ahambisane nemithetho elula:
- Lapho uphuma, sebenzisa isikrini selanga, noma ukhilimu onama-UF-filters. Inkomba yabo kufanele ibe okungenani 30.
- Sebenzisa imikhiqizo yokunakekela isikhumba ekhethiwe kahle.
Izindlela ezikhethiwe ezingakhethi zingathukuthelisa isikhumba. - Ngosuku olukhanyayo, olusenyangeni, kuhle ukugqoka isigqoko futhi umboze izindawo zesikhumba ezinemibala ngezingubo zokugqoka.
- Gwema i-wax epilation ngezilonda.
- Uma i-disorder pigmentation ibangelwa umphumela ohlangothini wemithi, kuphakanyiswa ukuyibeka esikhundleni noma ukuyikhipha, ngemuva kokubonisana nodokotela oya khona.
- Izinqubo zokuvotela kufanele zenziwe kusihlwa ukugwema ukuchayeka ilanga phakathi kwamahora angu-12-24 alandelayo.
