ʻEkolu mau kumu o ka ʻili ʻelemakule

ʻO ke kumu helu ʻekahi i ka ʻelemakule ʻana o ka ʻili:

Ka hoʻomālamalama UV, ka ʻelemakule kiʻi

70% o ka ʻelemakule ʻili e puka mai ana mai ka photoaging

Hoʻopilikia nā kukuna UV i ke kolakena i loko o ko mākou kino, ka mea e mālama ai i ka ʻili i ka ʻōpiopio. Inā emi ka kolakena, e emi ana ka elasticity o ka ʻili, e sagging, e palalulu, e like ʻole ke ʻano o ka ʻili, hyperpigmentation, pigmentation a me nā pilikia ʻili ʻē aʻe.

Ua māhele ʻia ka laulā ākea o ka lā i UVA a me UVB. He pōkole nā ​​nalu o nā kukuna UVB a hiki ke puhi wale i ka papa luna o ko mākou ʻili, ʻaʻole hiki ke komo hohonu i loko o ka ʻili; akā naʻe, he lōʻihi nā nalu o nā kukuna UVA a hiki ke komo ma o ke aniani a hohonu i loko o ka ʻili, a laila hoʻonāwaliwali i ka collagen a alakaʻi i ka ulu ʻana o nā wrinkles.

I nā huaʻōlelo maʻalahi, alakaʻi ka UVA i ka ʻelemakule, alakaʻi ka UVB i ka puhi ʻana, a hiki i ka mālamalama ultraviolet ke hōʻino i ka DNA cellular, hōʻemi i ka hana fibroblast, a ua ālai ʻia ka synthesis collagen, e alakaʻi ana i ka mutation cell, ka ʻelemakule, a me ka apoptosis. No laila, aia ka UV ma nā wahi āpau, inā he lā a he ao paha, pono ʻoe e hana i kahi hana maikaʻi o ka pale ʻana i ka lā.

ʻO ka lua o ka mea nui loa i ka ʻelemakule ʻana o ka ʻili

Nā radical manuahi oxidative

ʻO ka huaʻōlelo koʻikoʻi no nā radical manuahi ʻo 'oxygen'. Hanu mākou ma kahi o 98 a 99 pakeneka o ka oxygen i kēlā me kēia manawa a mākou e hanu ai; hoʻohana ʻia ia e puhi i ka meaʻai a mākou e ʻai ai a hoʻokuʻu i nā mole liʻiliʻi no kā mākou mau cell e metabolise, a hoʻokuʻu ia i ka nui o ka ikehu e hana ai ko mākou mau ʻiʻo.

Akā, malia paha he 1% a i ʻole 2% o ka oxygen e koho i kahi ala ʻokoʻa a weliweli hoʻi, ʻo kēia liʻiliʻi o ka oxygen, i kapa pinepine ʻia he mau radical manuahi, e hoʻouka ana i kā mākou mau cell. I ka hala ʻana o ka manawa, hōʻiliʻili kēia pōʻino i ka hala ʻana o ka manawa.

ʻO ka mea i ʻike nui ʻia, ʻo ia nā hōʻailona o ka ʻelemakule e ʻike ʻia ma ka ʻili. Loaʻa i ko mākou kino kahi ʻano pale e hoʻoponopono ai i ka pōʻino i hana ʻia i ko mākou mau cell e nā radical manuahi, akā i ka wā e hōʻiliʻili wikiwiki ai nā radical manuahi ma mua o ka hiki i nā cell o ke kino ke hoʻoponopono iā lākou, e ʻelemakule mālie ka ʻili.

ʻO ke kiʻi ma luna ka ʻiʻo ʻili maoli o ko mākou kino, hiki iā ʻoe ke ʻike maopopo he ʻeleʻele ka epidermis o luna a ʻoi aku ka mālamalama o ka dermis o lalo, ʻo ka dermis kahi a mākou e hana ai i ka collagen, a ʻo nā pūnaewele e hana ana i ka collagen ua kapa ʻia ʻo fibroblasts, he mau mīkini hana collagen.

ʻO nā fibroblasts ma waenakonu o ke kiʻi, ʻo ia nā fibroblasts, a ʻo ka ʻupena nananana a puni lākou he collagen. Hoʻopuka ʻia ke collagen e nā fibroblasts, a ʻo ka ʻili ʻōpio he pūnaewele collagen ʻekolu-dimensional a paʻa, me nā fibroblasts e huki ikaika ana i nā olonā collagen e hāʻawi i ka ʻili ʻōpio i kahi ʻano piha a laumania.

A ʻo ka ʻili kahiko, nā fibroblasts a me ka collagen link ma waena o ka disintegration o nā fibroblasts ʻelemakule e hōʻole pinepine i ke komo ʻana o ka collagen, i ka hala ʻana o ka manawa, ua hoʻomaka pū ka ʻili e ʻelemakule, ʻo ia ka mea a mākou e ʻōlelo pinepine ai i ka ʻelemakule ʻana o ka ʻili, pehea mākou e hoʻoponopono ai i ka oxidation o ka ʻili i loaʻa?

Ma waho aʻe o ka hoʻolohe pono ʻana i ka sunscreen, hiki iā mākou ke hoʻohana i kekahi me ka huaora A, ka huaora E, ka waikawa ferulic, resveratrol a me nā mea ʻē aʻe o nā huahana mālama ʻili; hiki ke ʻai pinepine i nā huaʻai a me nā mea kanu ʻālohilohi, e like me nā tōmato, waiwai nui nā tōmato i ka lycopene.

Hiki iā ia ke omo maikaʻi i ka oxygen a pale i ke kaumaha oxidative, hiki iā ʻoe ke ʻai hou aku i ka broccoli, aia ka broccoli i kahi ʻāpana i kapa ʻia ʻo glycosides ʻaila mustard, ma hope o ka lawe ʻana i kēia mea hana, e mālama ʻia lākou i loko o ka ʻili, i hiki i nā ʻili ʻili ke pale ponoʻī, hiki i kēia mau huaʻai a me nā mea kanu ke hoʻolaha i ke kūʻē ʻana o nā cell i ka ʻelemakule.

ʻO ke kolu o ka mea nui loa i ka ʻelemakule ʻana o ka ʻili

Ka glycation ʻili

ʻO ka Glycation, ma nā ʻōlelo loea, ua kapa ʻia ʻo ia he hopena glycosylation non-enzymatic a i ʻole he hopena Melad. ʻO ke kumumanaʻo, ʻo ke kō hōʻemi e hoʻopaʻa i nā protein i ka loaʻa ʻole o nā enzymes; hiki ke hoʻohuli nui ʻia nā kō hōʻemi me nā protein, a ke hele nei nā kō hōʻemi a me nā protein i kahi hopena oxidation lōʻihi, dehydrogenation, a me ka hoʻonohonoho hou ʻana, e hopena ana i ka hana ʻana o nā huahana hopena glycosylation hope loa, a i ʻole AGEs no ka pōkole.

ʻO nā AGEs kahi hui o nā ʻōpala olaola i hoʻihoʻi ʻole ʻia, melemele-ʻeleʻele, pili i ka makaʻu ʻole i ka luku ʻia ʻana o nā enzyme, a ʻo ia kekahi o nā kumu nui o ka ʻelemakule kanaka. I ko kākou ʻelemakule ʻana, hōʻiliʻili nā AGEs i loko o ke kino, e alakaʻi ana i ka hoʻonui ʻia o ka paʻakikī o nā paia o loko o nā kīʻaha koko, kahi kaulike ʻole i ka metabolism iwi e alakaʻi ana i ka osteoporosis, a me ka luku ʻia ʻana o nā olonā collagen a me elastin i loko o ka dermis e alakaʻi ana i ka ʻelemakule ʻili. Ua hōʻuluʻulu ʻia ka ʻelemakule ʻili i hoʻokumu ʻia e ka glycation i loko o hoʻokahi ʻōlelo: luku ke kō i nā protein olakino a hoʻololi i nā ʻano protein ʻōpio i nā ʻano protein kahiko, e alakaʻi ana i ka ʻelemakule a me ka nalowale o ka elasticity o nā olonā collagen a me elastic i loko o ka dermis.
