Kuki uruhu rurerutse?

80% by'uruhu rw'umuntu ni kolajeni, kandi muri rusange nyuma y'imyaka 25, umubiri w'umuntu uzajya mu gihe cyo kugabanuka kwa kolajeni. Kandi iyo imyaka igeze kuri 40, kolajeni iri mu ruhu izaba iri mu gihe cyo kugabanuka gukomeye, kandi ingano ya kolajeni yayo ishobora kuba munsi ya kimwe cya kabiri cy'iyo ifite imyaka 18.

1. Kubura poroteyine mu ruhu:

Kolajeni na elastine, bishyigikira uruhu kandi bigatuma rukomera. Nyuma y'imyaka 25, izi poroteyine ebyiri ziragabanuka bitewe n'uko umubiri w'umuntu usaza, hanyuma bigatuma uruhu rutakaza ubushobozi bwo kwiyubaka; Mu gihe cyo kubura kolajeni, imigozi ya kolajeni n'urusobe rw'imitsi bishyigikira uruhu biracika, bigatera ibimenyetso byo kuzura kw'imitsi y'uruhu, gucika intege, ndetse no gusenyuka, maze uruhu rukagenda rurekura.

2. Imbaraga zishyigikira uruhu ziragabanuka:

Ibinure n'imitsi ni byo bishyigikira uruhu cyane, mu gihe kubura ibinure byo munsi y'umubiri no kuruhuka kw'imitsi biterwa n'impamvu zitandukanye nko gusaza no kudakora imyitozo ngororamubiri bituma uruhu rutakaza inkunga no kugabanuka.

3. Irimo umwimerere n'iy'inyuma:

Gusaza k'uruhu biterwa no gusaza kw'uruhu haba mu mubiri no hanze. Inzira yo gusaza ituma imiterere y'uruhu igabanuka ndetse n'imikorere yarwo ihinduka. Gusaza kw'uruhu ahanini bigenwa na za gene, kandi ntibisubirwaho, kandi bifitanye isano na radicals libre, glycosylation, endocrine, nibindi. Nyuma yo gusaza, gutakaza amavuta y'uruhu, kugabanuka k'uruhu, no gukora aside hyaluronic biba biri hasi ugereranije n'igipimo cyo gutakaza, bigatuma uruhu rutakaza ubushobozi bwo kumererwa neza no kugabanuka. Gusaza kw'iminkanyari hanze y'uruhu ahanini guterwa n'izuba, rinafitanye isano no kunywa itabi, kwangiza ibidukikije, kwita ku ruhu nabi, imbaraga z'umubiri, nibindi.

4. UV:

80% by'ubusaza bw'isura buterwa n'izuba. Kwangirika kwa UV ku ruhu ni igikorwa cyiyongera, gikurikiza inshuro, igihe n'ubukana bw'izuba, ndetse no kurinda uruhu ibara ryarwo. Nubwo uruhu ruzakoresha uburyo bwo kwikingira iyo rwangiritse na UV. Koresha melanocytes mu gice cy'ibanze kugira ngo rukore umukara mwinshi kandi ruwujyane hejuru y'uruhu kugira ngo rufate imirasire ya UV, rugabanye kwangirika kwa UV, ariko imirasire imwe ya UV izakomeza kwinjira muri dermis, isenye imiterere ya collagen, ibura rya aside hyaluronic, igabanuka rya fibre elastic, hamwe n'umubare munini wa radicals free, bigatuma habaho izuba, kuruhuka, uruhu rwumye kandi rudakomeye, ndetse n'imitsi miremire. Bityo rero, izuba rigomba gukorwa umwaka wose.

5. Ibindi bintu:

Urugero, imbaraga rukuruzi, umurage, imihangayiko yo mu mutwe, kwibasirwa n'izuba no kunywa itabi nabyo bihindura imiterere y'uruhu, amaherezo bigatuma uruhu rutakaza ubushobozi bwarwo bwo kwiyubaka, bigatuma ruruhuka.

Incamake:

Gusaza k'uruhu biterwa n'ibintu byinshi. Mu bijyanye no kuvura, tugomba gutangirira ku miterere y'uruhu n'impamvu zo gusaza, hanyuma tugahindura uburyo bwo kuvura mu buryo bwa siyansi. Iyo habayeho iminkanyari nyayo, biragoye ko imiti isanzwe yo kwita ku ruhu kuyikuraho neza. Inyinshi muri zo zigomba guhuzwa no kuvuraibikoresho byo kwisigagukora kuri dermis kugira ngo habeho ingaruka zo gukuraho iminkanyari, nkoUburyo bwo kuvura MTS mesoderm, umurongo wa radiyo, urushinge rw'amazi, laser, kuzuza ibinure, uburozi bwa botulinum, nibindi.
