Ibintu bitatu byuruhu

Umubare umwe mu rukundo ashaje:

Imirasire ya UV, gufotora

70% by'uruhu gusa bikomoka kumafoto

Uv Imirasire igira ingaruka kuri colagen mumubiri wacu, ituma uruhu rusa nabakiri bato. Niba colagen igabanuka, uruhu ruzagabanuka, runyeganyega, gusebanya, guhuza uruhu, ibara, hyperpigmetion, pinkment hamwe nibindi bibazo byuruhu.

Imyitozo ngororamubiri yagutse yigabanyijemo uva na UVB. UVB Ray ifite uburebure buke kandi irashobora gutwika gusa uruhu rwacu, rudashobora kwinjira cyane kuruhu; Nyamara, uva imirasire ifite uburebure burebure kandi irashobora kwinjira mu kirahure kandi yinjira mu ruhu, amaherezo ikagira intege nke kandi ikaganisha ku iterambere ryinkinks.

Mu magambo yoroshye, UVA atera gusaza, UVB iganisha ku gutwika, kandi urumuri rwa ultraviolet rushobora kwangiza ADN ya selile, kugabanya ibikorwa bya fibroblast, na synthesis ya fibroblast, hamwe na synthesis ya fibroblast, biganisha kuri mutation, gusaza, na apoptose. Noneho, UV iri hose, yaba izuba cyangwa ibicu, ugomba gukora akazi keza ko kurinda izuba.

Ikintu cya kabiri cyingenzi mu ruhu gusa

Okiside yubusa

Ijambo ryibanze kubusa ni 'ogisijeni'. Twahumeka hafi 98 kugeza 99 ku ijana bya ogisijeni igihe cyose duhumeka; Byakoreshejwe mugutwika ibiryo turya no kurekura molekile nto kuri selile zacu kuri metabolise, kandi isohoza imbaraga nyinshi kugirango imitsi yacu ikore.

Ariko birashoboka 1% cyangwa 2% ya ogisijeni ihitamo inzira itandukanye kandi iteje akaga, iyi mpinga nkeya ya ogisijeni, yakunze kwita imirasire yubusa, itera selile. Igihe kirenze, ibi byangiritse ku gihe.

Ibigaragara cyane nibimenyetso byo gusaza byerekana kuruhu. Umubiri wacu ufite uburyo bwo kwirwanaho gusana ibyangijwe na selile zacu kubuntu, ariko iyo radicals yegeranya byihuse kurenza selile yumubiri irashobora kubakoraho, uruhu buhoro buhoro.

Ishusho hejuru nimpapuro nyazo zumubiri, urashobora kubona neza ko epidermis yo hejuru yijimye, dermis niho tubyara amakoni, kandi selile itanga amashini ya fibroblasts, zitera amashini.

Fibroblasts hagati yishusho ni fibroblasts, kandi urubuga rwigitagangurirwa ruzengurutse ni collagen. Collagen ikorwa na fibroblasts, hamwe nuruhu ruto ni urwego rwagati kandi rwongeye kuboha, hamwe na fibroblas gukurura fibre kugirango uhe uruhu ruto kugirango ruhe imiterere nyayo kandi yoroshye.

Kandi uruhu rwa kera, fibroblasts hamwe na colagen ihuriro hagati yo gusenyuka kwa fibroblasts, mugihe, uruhu na rwo rwatangiye gusaza uruhinja, dukemura dukemuke ku ruhu rwakiriwe?

Usibye kwitondera cyane izuba, turashobora gukoresha bamwe hamwe na vitamine A, acide ya Frulike, reveratrol nibindi bikoresho bitwara uruhu; Mubisanzwe birashobora kandi kurya imbuto zinyamanswa n'imboga nziza cyane, nk'inyanya, inyanya zikungahaye muri lycopene.

Irashobora gukuramo ogisijeni neza kandi ikabuza imihangayiko ya okiside, urashobora kandi kurya byinshi broccoli, broccoli ikubiyemo ibintu byamavuta ya sinapi, nyuma yo gufata uruhu, kuburyo selile yimbuto ishobora kwiringira, izi mbogo nimboga zirashobora guteza imbere ubukuru.

Ikintu cya gatatu cyingenzi mu ruhu gusa

Uruhu

Glycation, mumagambo yabigize umwuga, yitwa Sylesmatic Glycosylation Reaction cyangwa reaction ya Melad. Ihame nuko kugabanya isukari ihambira poroteyine mugihe enzymes; Kugabanya isukari birasubirwamo cyane hamwe na poroteyine, no kugabanya isukari hamwe na poroteyine zirimo okiside ndende, umwuma uva, no gusubirwamo.

Imyaka ni itsinda ryamatsinda adasubirwaho, umuhondo-wijimye, ufitanye isano namavuta adatinya kurimbuka kwa enzyme, kandi nimwe murugero rwibanze rwumusaza. Mugihe tumaze imyaka myinshi Imiterere, iganisha ku gusaza no gutakaza elastique ya colagen na fibre ya elasitike muri dermis.
