Kutheni ulusu lukhululekile?

I-80% yesikhumba somntu yi-collagen, kwaye ngokubanzi emva kweminyaka eyi-25, umzimba womntu uya kungena kwixesha eliphakamileyo lokulahleka kwe-collagen. Kwaye xa ubudala bufikelela kwi-40, i-collagen eluswini iya kuba kwixesha lokulahlekelwa ngokukhawuleza, kwaye umxholo wayo we-collagen unokuba ngaphantsi kwesiqingatha salo kwiminyaka eyi-18.

1. Ukulahleka kweprotheyini kwidermis:

I-Collagen kunye ne-elastin, exhasa ulusu kwaye iyenze ibe yimfumba kwaye yomelele. Emva kweminyaka engama-25, ezi proteni zimbini ngokwemvelo ziyancipha ngenxa yokuguga komzimba womntu, kwaye emva koko zenza ulusu lulahlekelwe ukuqina; Kwinkqubo yokulahleka kwe-collagen, i-collagen peptide bond kunye ne-elastic network exhasa ulusu iya kwaphuka, okukhokelela kwiimpawu ze-oxidation yezicubu zolusu, i-atrophy, kunye nokuwa, kwaye ulusu luya kukhululeka.

2. Amandla okuxhasa ulusu ayancipha:

I-Fat kunye ne-muscle iyona nkxaso enkulu yesikhumba, ngelixa ukulahlekelwa kwe-fat subcutaneous kunye nokuphumla kwemisipha okubangelwa izizathu ezahlukahlukeneyo ezifana nokuguga kunye nokungabikho kokuzivocavoca kwenza ulusu lulahlekelwe yinkxaso kunye ne-sag.

3. Endogenous kwaye exogenous:

Ukuguga kwesikhumba kubangelwa kukuguga okungapheliyo kunye nokuphuma ngaphandle. Inkqubo yokuguga ikhokelela ekwehleni kwengqibelelo yesakhiwo solusu kunye nomsebenzi womzimba. Ukuguga kwe-endogenous kumiselwa ikakhulu yimfuza, kwaye ayinakuguqulwa, kwaye inxulumene ne-radicals yamahhala, i-glycosylation, i-endocrine, njl. Emva kokuguga, ukulahleka kwezicubu ze-adipose yesikhumba, ukuncipha kwesikhumba, kunye ne-collagen kunye ne-hyaluronic acid synthesis rate iphantsi kunomlinganiselo welahleko. , okukhokelela ekulahlekeni kwe-atrophic yesikhumba se-elasticity kunye ne-sagging. Ukuguga kwangaphandle kwemibimbi kubangelwa ikakhulu kukukhanya kwelanga, okukwanxulumene nokutshaya, ukungcoliseka kwendalo, ukhathalelo olungalunganga lwesikhumba, ubunzima, njalo njalo.

4. UV:

I-80% yokuguga kobuso ibangelwa kukukhanya kwelanga. Umonakalo we-UV kulusu yinkqubo eyongezelekayo, elandela amaxesha amaninzi, ubude bexesha kunye nobunzulu bokuchanabeka elangeni, kunye nokukhuselwa kolusu lwebala layo. Nangona ulusu luya kuvula indlela yokuzikhusela xa yonakaliswe yi-UV. Vula i-melanocytes kumqolo we-basal ukudibanisa inani elikhulu lomnyama kwaye uhambise kumphezulu wolusu ukufunxa imitha ye-ultraviolet, ukunciphisa umonakalo wemitha ye-ultraviolet, kodwa eminye imitha ye-ultraviolet isaza kungena kwidermis, itshabalalise indlela ye-collagen, ilahleko yeasidi ye-hyaluronic, i-elastic fiber atrophy, kunye nenani elikhulu leeradicals zasimahla, ezikhokelela ekukhanyeni kwelanga, ukuphumla, ukomisa kunye nolusu olurhabaxa, kunye nemibimbi enzulu yezihlunu. Ngoko ke, i-sunscreen kufuneka yenziwe unyaka wonke.

5. Eminye imiba:

Umzekelo, umxhuzulane, ufuzo, uxinzelelo lwengqondo, ukukhanya kwelanga kunye nokutshaya kwakhona ukuguqula isakhiwo solusu, kwaye ekugqibeleni wenze ulusu lulahlekelwe ukunyameka, okubangela ukuphumla.

Isishwankathelo:

Ukuguga kolusu kubangelwa zizinto ezininzi. Ngokumalunga nolawulo, kufuneka siqale ngemeko yolusu kunye nezizathu zokuguga, kwaye senze ngokwesayensi ulawulo. Nje ukuba imibimbi yokwenyani iveliswe, kunzima kwiimveliso zokhathalelo lwesikhumba ngokubanzi ukuba zisuswe ngempumelelo. Uninzi lwazo kufuneka zidityaniswe nolawulo lweizixhobo zobuhleukwenza kwi dermis ukufikelela isiphumo ukususwa imibimbi, ezifanaUnyango lwe-MTS mesoderm, amaza onomathotholo, inaliti yokukhanya kwamanzi, i-laser, ukuzaliswa kwamafutha, i-botulinum toxin, njl.
