Kungani isikhumba sikhululekile?

Isikhumba somuntu esingu-80% siyi-collagen, futhi ngokuvamile ngemva kweminyaka engu-25, umzimba womuntu uzongena esikhathini esiphezulu sokulahlekelwa yi-collagen. Futhi lapho iminyaka ifinyelela ku-40, i-collagen esikhumbeni izoba sesikhathini sokulahlekelwa okukhulu, futhi okuqukethwe yi-collagen yayo kungaba ngaphansi kwengxenye yalokho lapho eneminyaka engu-18.

1. Ukulahlekelwa yiprotheni ku-dermis:

I-Collagen ne-elastin, ezisekela isikhumba futhi zisenze sibe sikhulu futhi siqine. Ngemva kweminyaka engu-25, lawa maprotheni amabili ancipha ngokwemvelo ngenxa yenqubo yokuguga komzimba womuntu, bese enza isikhumba silahlekelwe ukuqina; Enkambisweni yokulahlekelwa yi-collagen, izibopho ze-collagen peptide kanye nenethiwekhi enwebekayo esekela isikhumba kuzophuka, okuholela ezimpawini zokubola kwezicubu zesikhumba, ukuwohloka, ngisho nokuwa, futhi isikhumba sizokhululeka.

2. Amandla asekelayo esikhumba ayancipha:

Amafutha nemisipha kuyizinto ezisekela kakhulu isikhumba, kanti ukulahlekelwa amafutha angaphansi kwesikhumba kanye nokuphumula kwemisipha okubangelwa yizizathu ezahlukahlukene njengokuguga kanye nokuntuleka kokuzilolonga kwenza isikhumba silahlekelwe ukwesekwa nokuwohloka.

3. Okuvela ngaphandle kanye nokuvela ngaphandle:

Ukuguga kwesikhumba kubangelwa ukuguga kwesikhumba okungokwemvelo nokungaphandle. Inqubo yokuguga iholela ekwehleni kokuqina kwesakhiwo sesikhumba kanye nokusebenza komzimba. Ukuguga kwesikhumba okungokwemvelo kunqunywa kakhulu yizakhi zofuzo, futhi akunakuphikiswa, futhi kuhlobene nama-free radicals, i-glycosylation, i-endocrine, njll. Ngemva kokuguga, ukulahleka kwezicubu zesikhumba, ukuncipha kwesikhumba, kanye nesilinganiso sokwenziwa kwe-collagen ne-hyaluronic acid kuphansi kunesilinganiso sokulahlekelwa, okuholela ekulahlekelweni kokuqina kwesikhumba okungapheli kanye nokuwa. Ukuguga kwangaphandle kwemibimbi kubangelwa kakhulu ukukhanya kwelanga, okuhlobene nokubhema, ukungcola kwemvelo, ukunakekelwa kwesikhumba okungalungile, amandla adonsela phansi, njalo njalo.

4. I-UV:

Ukuguga kobuso okungu-80% kubangelwa ukukhanya kwelanga. Ukulimala kwe-UV esikhumbeni kuyinqubo eqoqanayo, elandela ukuvama, ubude kanye namandla okuchayeka elangeni, kanye nokuvikelwa kwesikhumba kombala waso. Nakuba isikhumba sizosebenzisa indlela yokuzivikela uma sonakaliswa yi-UV. Sebenzisa ama-melanocyte engqimbeni engezansi ukuze uhlanganise inani elikhulu lomnyama bese uwuthutha uye ebusweni besikhumba ukuze umunce imisebe ye-ultraviolet, unciphise umonakalo wemisebe ye-ultraviolet, kodwa eminye imisebe ye-ultraviolet isazongena esikhumbeni, ibhubhise indlela yokusebenza kwe-collagen, ukulahleka kwe-hyaluronic acid, i-elastic fiber atrophy, kanye nenani elikhulu lama-free radicals, okuholela ekushiseni kwelanga, ukuphumula, isikhumba esomile nesiqinile, kanye nemibimbi yemisipha ejulile. Ngakho-ke i-sunscreen kumele yenziwe unyaka wonke.

5. Ezinye izici:

Isibonelo, amandla adonsela phansi, ufuzo, ukucindezeleka kwengqondo, ukuchayeka elangeni kanye nokubhema nakho kuguqula isakhiwo sesikhumba, futhi ekugcineni kwenze isikhumba silahlekelwe ukuqina kwaso, okuholela ekuphumuleni.

Isifinyezo:

Ukuguga kwesikhumba kubangelwa yizici eziningi. Ngokuphathelene nokuphathwa, sidinga ukuqala ngesimo sesikhumba kanye nezizathu zokuguga, futhi senze ngendlela efanele ukuphathwa ngokwesayensi. Uma imibimbi yangempela isivele ikhiqizwe, kunzima ngemikhiqizo yokunakekelwa kwesikhumba ejwayelekile ukuyisusa ngempumelelo. Iningi layo lidinga ukuhlanganiswa nokuphathwa kweimishini yobuhleukusebenza ku-dermis ukuze kufezwe umphumela wokususa imibimbi, njengokuthiUkwelashwa kwe-MTS mesoderm, imvamisa yomsakazo, inaliti yokukhanya kwamanzi, i-laser, ukugcwalisa amafutha, ubuthi be-botulinum, njll.
