Kungani isikhumba sikhululekile?

I-80% yesikhumba somuntu yi-collagen, futhi ngokuvamile ngemva kweminyaka engu-25, umzimba womuntu uzongena esikhathini esiphezulu sokulahlekelwa kwe-collagen.Futhi lapho iminyaka ifinyelela ku-40, i-collagen esikhumbeni izoba sesikhathini sokulahlekelwa okukhulu, futhi okuqukethwe kwayo kwe-collagen kungase kube ngaphansi kwesigamu salokho lapho eneminyaka engu-18.

1. Ukulahlekelwa amaprotheni kudermis:

I-Collagen ne-elastin, esekela isikhumba futhi isenze sibe sikhulu futhi siqine.Ngemva kweminyaka engu-25, la maprotheni amabili ayancipha ngokwemvelo ngenxa yenqubo yokuguga komzimba womuntu, bese enza isikhumba silahlekelwe ukunwebeka;Enkambweni yokulahlekelwa kwe-collagen, izibopho ze-collagen peptide kanye nenethiwekhi yokunwebeka esekela isikhumba izophulwa, okuholela ezimpawu ze-oxidation yezicubu zesikhumba, i-atrophy, ngisho nokuwa, futhi isikhumba sizokhululeka.

2. Amandla asekelayo esikhumba ayancipha:

Amafutha kanye nemisipha kukhona ukwesekwa okukhulu kwesikhumba, kuyilapho ukulahlekelwa kwamafutha angaphansi kwesikhumba kanye nokuphumula kwemisipha okubangelwa izizathu ezihlukahlukene ezifana nokuguga nokuntuleka kokuzivocavoca kwenza isikhumba silahlekelwe ukusekelwa futhi sigxume.

3. Endogenous futhi exogenous:

Ukuguga kwesikhumba kubangelwa kokubili ukuguga kwe-endogenous kanye ne-exogenous.Inqubo yokuguga iholela ekwehleni kobuqotho besakhiwo sesikhumba kanye nokusebenza komzimba.Ukuguga kwe-Endogenous kunqunywa ikakhulukazi izakhi zofuzo, futhi akunakuhlehliswa, futhi kuhlobene nama-radicals mahhala, i-glycosylation, i-endocrine, njll. Ngemva kokuguga, ukulahlekelwa kwezicubu ze-adipose yesikhumba, ukuncipha kwesikhumba, kanye ne-collagen ne-hyaluronic acid synthesis rate iphansi kunezinga lokulahlekelwa. , okuholela ekulahlekelweni kwe-atrophic kwesikhumba sokunwebeka nokuwohloka.Ukuguga kwangaphandle kwemibimbi kubangelwa ikakhulukazi ukukhanya kwelanga, okuhlobene nokubhema, ukungcoliswa kwemvelo, ukunakekelwa kwesikhumba okungalungile, amandla adonsela phansi, njalonjalo.

4. UV:

I-80% yokuguga kobuso ibangelwa ukukhanya kwelanga.Ukulimala kwe-UV esikhumbeni kuyinqubo enqwabelanayo, elandela imvamisa, ubude besikhathi kanye namandla okuchayeka elangeni, kanye nokuvikelwa kwesikhumba sombala wayo siqu.Nakuba isikhumba sizovula indlela yokuzivikela uma sonakaliswa yi-UV.Yenza kusebenze ama-melanocyte kungqimba lwe-basal ukuze ahlanganise inani elikhulu lomnyama futhi uwuhambise ebusweni besikhumba ukuze ubambe imisebe ye-ultraviolet, unciphise ukulimala kwemisebe ye-ultraviolet, kodwa eminye imisebe ye-ultraviolet isazongena ku-dermis, ibhubhise indlela ye-collagen, ukulahleka kwe-hyaluronic acid, i-elastic fibre atrophy, kanye nenani elikhulu lama-radicals mahhala, okuholela ekukhanyeni kwelanga, ukukhululeka, isikhumba esomile nesiqinile, kanye nemibimbi ejulile yemisipha.Ngakho-ke, i-sunscreen kufanele yenziwe unyaka wonke.

5. Ezinye izici:

Isibonelo, amandla adonsela phansi, ufuzo, ukucindezeleka kwengqondo, ukuchayeka elangeni nokubhema nakho kuguqula isakhiwo sesikhumba, futhi ekugcineni kwenza isikhumba silahlekelwe ukunwebeka, okuholela ekuphumuleni.

Isifinyezo:

Ukuguga kwesikhumba kubangelwa izici eziningi.Mayelana nokuphatha, sidinga ukuqala ngesimo sesikhumba kanye nezizathu zokuguga, futhi senze ukuphatha ngendlela oyifisayo.Uma imibimbi yeqiniso isikhiqiziwe, kuba nzima ngemikhiqizo yokunakekelwa kwesikhumba ejwayelekile ukuyisusa ngempumelelo.Iningi lazo lidinga ukuhlanganiswa nokuphathwa kweizinto zobuhleukwenza ku-dermis ukuze kuzuzwe umphumela wokukhipha imibimbi, njengeUkwelashwa kwe-MTS mesoderm, imvamisa yomsakazo, inaliti yokukhanya kwamanzi, i-laser, ukugcwaliswa kwamafutha, ubuthi be-botulinum, njll.
