Zvinhu zvitatu zvekukwegura ganda

Iyo nhamba yekutanga mune yeganda kuchembera:

UV radiation, Photoging

70% yeganda rekuchera rinobva kuPlactor

UV ravha inokanganisa collagen mumuviri wedu, inochengetedza ganda riripo mudiki. Kana collagen ichicheka, ganda rinodzikira kusvika pakupera, kusimuka, kusvibisa, kusaenzana ganda toni, hyperpigmentation, pigmentation uye mamwe matambudziko eganda.

Spect yeStle's spectrum yakakamurwa muUVA uye UVB. UVB marara ane mapfumo mapfupi uye anogona kungopisa kumusoro kweganda redu, kutadza kupinda mukati meganda; Nekudaro, uva riys ine refu wavelength uye inogona kupinda mukati megirazi uye yakadzika muganda, pakupedzisira ichishungurudza collagen uye inotungamira kukuvadzwa kwemakonzo.

Mukutaura zviri nyore, Uva anotungamira pakukwegura, Uvb anotungamira mukupisa, uye ultraviol clight inogona kukuvadza cellar, uye collagen synthesis yakavharwa, inotungamira kuchitokisi, kuchembera, uye apoposis. Saka, UV iri kwese kwese, kunyangwe izuva kana makore, iwe unofanirwa kuita basa rakanaka rekudzivirira zuva.

Chechipiri chakakosha chinhu mune ganda kukwegura

Oxidative yemahara radicals

Izwi rakakosha remahara radicals ndeye 'okisijeni'. Isu tinofema dzinenge 98 kusvika 99 muzana yeokisijeni nguva dzese dzatinofema; Rinoshandiswa kupisa chikafu chatinodya uye kuburitsa madiki madiki emasero edu kuti metabolise, uye inoburitsa simba rakawanda kuita kuti tsandanyama yedu ive basa.

Asi pamwe 1% kana 2% yeokisijeni inosarudza nzira dzakasiyana uye ine ngozi, iyi diki yeokisijeni, inowanzodaidzwa kuti ma radicals, inokonesa masero edu. Nekufamba kwenguva, kukuvara uku kunounganidza nekufamba kwenguva.

Zvinonyanya kuoneka zviratidzo zvekukwegura zvinoratidza paganda. Muviri wedu une muchina wekudzivirira unogadzirisa kukuvadzwa kwakaitwa kumasero edu nemahara zvemahara, asi kana radicals emahara dzinogona kuzviisa pasi pemasero emuviri anogona kuigadzirisa, ganda rinopfuura.

Mufananidzo uri pamusoro ndewe ganda reganda reganda remuviri wedu, unogona kunyatsoona kuti iyo Epidermis yakasviba

Iyo fibroblasts iri pakati pemufananidzo ndiwo ma fibroblasts, uye iyo spider web yakavakomberedza ndeye collagen. Collagen inogadzirwa neFibroblasts, uye ganda rechidiki uye rakapetwa uye rakanyatsoita colagen network, neFibroblasts zvine simba kudhonza pamazita emillage kuti ape ganda diki uye rakanyatsogadzikana.

Uye ganda rekare uye fibroblasts uye collagen link pakati pekuparadzira fibroblasts anowanzo kuramba kupinda, nekufamba kwenguva, izvi zvatinowanzove neganda kuchembera, tinogadzirisa sei manzwi eganda akagamuchira?

Pamusoro pekutarisa zvakanyanya kune sunscreen, tinogona kushandisa imwe neVitamin a, vitamini e, ferlic acid, resverurl uye zvimwe zvigadzirwa zveganda zvekutarisira kweganda; Kazhinji inogona zvakare kudya michero yakajeka ine mavara uye miriwo, senge matomatisi, matomatisi akapfuma muLycopene.

Inogona kutora oxygen mushe uye kudzivirira oxidative kushushikana, broccoli ine chikamu chinonzi mafuta egwenzi, mushure mekudya kweganda, kuti zvibereko zvinogona kuzvidzivirira, michero nemiriwo izvi zvinogona kusimudzira kudzikisira kwesero pakukwegura.

Chetatu chakanyanya kukosha chinhu mukukwegura kweganda

Ganda ganda

Glycation, mune nyanzvi yehunyanzvi, inonzi isiri-ye enzymatic glycosylation yekuita kana iyo melad maitiro. Iyo nheyo ndeyekuti kuderedza mashuga kunosunga mapuroteni musipo we enzymes; Kuderedza mashuga kunotsanangurwa zvakanyanya nemapuroteni, uye kuderedza mashuga uye mapuroteni anodzora oxidation, kushomeka kwezvinhu, zvichikonzera kugadzirwa kwechiitiko chekupedzisira cheGlycosylation end-zvigadzirwa, kana mazera kwenguva pfupi.

Mazera iboka rekusaziva, yero-yero-brownish, yakabatana mabheji ekubereka vasingatyi zvekuparadza kwe enzyme, uye ndeimwe yemapuranga makuru ekukwegura kwevanhu. Sezvatinoshuwira mumuviri, zvichitungamira mukuwedzera kwemaruva emukati emidziyo yeropa, uye shuwa inoparadza mapuroteni ezvivakwa inotungamira pakukwegura uye kurasikirwa kwe elasticity yeColagen uye elastic Fibers muDermis.
