Kuki uruhu rudakabije?

80% by'uruhu rw'umuntu ni kolagen, kandi muri rusange nyuma yimyaka 25, umubiri wumuntu uzinjira mugihe cyo gutakaza kolagen. Kandi iyo imyaka igeze kuri 40, kolagen mu ruhu izaba iri mugihe cyo gutakaza neza, kandi ibiyigize bya kolagen bishobora kuba bitarenze kimwe cya kabiri cyabyo kumyaka 18.

1. Gutakaza poroteyine muri dermisi:

Kolagen na elastine, ifasha uruhu kandi igatera kandi igakomera. Nyuma yimyaka 25, izo proteyine zombi zisanzwe zigabanuka bitewe nubusaza bwumubiri wumuntu, hanyuma bigatuma uruhu rutakaza elastique; Mugihe cyo gutakaza kolagen, imiyoboro ya peptide ya peptide hamwe numuyoboro wa elastike ushyigikira uruhu bizacika, bikavamo ibimenyetso bya okiside yumubiri wuruhu, atrophy, ndetse bigasenyuka, kandi uruhu ruzaba rudakabije.

2. Imbaraga zifasha uruhu ziragabanuka:

Ibinure n'imitsi ninkunga nini yuruhu, mugihe gutakaza ibinure byo munsi yubutaka no kuruhura imitsi biterwa nimpamvu zitandukanye nko gusaza no kudakora siporo bituma uruhu rutakaza inkunga kandi rukagabanuka.

3. Endogenous and exogenous:

Gusaza k'uruhu biterwa no gusaza kwa endogenous na exogenous. Inzira yo gusaza itera kugabanuka k'uburinganire bwuruhu rwimikorere nimikorere ya physiologique. Gusaza kwa endogenous kugenwa ahanini na gen, kandi ntibisubirwaho, kandi bifitanye isano na radicals yubusa, glycosylation, endocrine, nibindi. , bikaviramo gutakaza uruhu rwa atrophike gutakaza elastique no kugabanuka. Gusaza hanze yiminkanyari biterwa ahanini nizuba ryizuba, nabyo bifitanye isano no kunywa itabi, kwanduza ibidukikije, kwita kuburuhu nabi, uburemere, nibindi.

4. UV:

80% byo gusaza mu maso biterwa nizuba. UV yangiza uruhu ninzira yo guteranya, ikurikira inshuro, igihe nuburemere bwizuba ryizuba, ndetse no kurinda uruhu rwibara ryarwo. Nubwo uruhu ruzakora uburyo bwo kwikingira iyo rwangijwe na UV. Koresha melanocytes murwego rwibanze kugirango ushushanye umubare munini wumukara hanyuma uyijyane hejuru yuruhu kugirango ikure imirasire ya ultraviolet, igabanye kwangirika kwimirasire ya ultraviolet, ariko imirasire ya ultraviolet iracyinjira muri dermisi, isenya uburyo bwa kolagen, gutakaza aside ya hyaluronike, atrophy ya fibre ya elastique, hamwe numubare munini wa radicals yubusa, bikavamo suntan, kuruhuka, uruhu rwumye kandi rukomeye, hamwe n’imitsi yimbitse. Izuba ryizuba rero rigomba gukorwa umwaka wose.

5. Ibindi bintu:

Kurugero, uburemere, kuragwa, guhangayika mumutwe, guhura nizuba ryizuba no kunywa itabi nabyo bihindura imiterere yuruhu, hanyuma amaherezo bigatuma uruhu rutakaza ubukana, bikaviramo kuruhuka.

Incamake:

Gusaza k'uruhu biterwa n'impamvu nyinshi. Kubijyanye nubuyobozi, dukeneye guhera kumiterere yuruhu nimpamvu zisaza, kandi tugahindura mubuhanga mubuhanga. Iyo iminkanyari nyayo imaze gukorwa, biragoye kubicuruzwa rusange byita kuruhu kubikuraho neza. Benshi muribo bakeneye guhuzwa nubuyobozi bwaibikoresho by'ubwizagukora kuri dermis kugirango ugere ku ngaruka zo gukuraho inkari, nkaUbuvuzi bwa MTS mesoderm, radiyo inshuro nyinshi, urushinge rwamazi rwamazi, laser, kuzuza ibinure, uburozi bwa botuline, nibindi.
