ʻEkolu mau mea o ka ʻili kahiko

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

ʻO ka hoʻoheheʻe UV, ke kiʻi ʻana

ʻO 70% o ka ʻelemakule ʻili mai ka photoaging

Hoʻopilikia nā kukuna UV i ka collagen i loko o ko mākou kino, e mālama i ka ʻili i ka ʻōpio. Inā emi ka collagen, e emi ana ka elasticity o ka ʻili, sagging, dullness, uneven skin leo, hyperpigmentation, pigmentation a me nā pilikia ʻē aʻe.

Ua māhele ʻia ka laulā ākea o ka lā i UVA a me UVB. ʻO nā kukuna UVB he mau nalu pōkole 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 mau hawewe lōʻihi nā kukui UVA a hiki ke komo i loko o ke aniani a hohonu i loko o ka ʻili, e hoʻonāwaliwali i ka collagen a alakaʻi i ka ulu ʻana o nā wrinkles.

Ma nā ʻōlelo maʻalahi, alakaʻi ʻo UVA i ka ʻelemakule, UVB ke alakaʻi i ke ahi, a hiki i ka kukui ultraviolet ke hōʻino i ka DNA cellular, hoʻemi i ka hana fibroblast, a paʻa ʻia ka synthesis collagen, e alakaʻi ana i ka mutation cell, ka ʻelemakule, a me ka apoptosis. No laila, aia ʻo UV ma nā wahi āpau, inā he lā a ʻeleʻele paha, pono ʻoe e hana maikaʻi i ka pale ʻana i ka lā.

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

ʻO nā radical manuahi oxidative

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

Akā, hiki paha i ka 1% a i ʻole 2% o ka oxygen ke koho i kahi ala ʻokoʻa a me ka pōʻino, ʻo kēia wahi liʻiliʻi o ka oxygen, i kapa pinepine ʻia he radical manuahi, e hoʻouka i kā mākou mau cell. I ka wā lōʻihi, hoʻonui kēia pōʻino i ka manawa.

ʻO ka mea iʻike nuiʻia,ʻo ia nā hōʻailona o kaʻelemakule e hōʻike ana ma kaʻili. Loaʻa i ko mākou kino kahi hana pale e hoʻoponopono ai i ka pōʻino i hana ʻia e nā radical manuahi, akā inā ʻoi aku ka wikiwiki o ka hōʻiliʻili ʻana o nā radical manuahi ma mua o ka hiki i ke kino ke hoʻoponopono iā lākou, e ulu mālie ka ʻili.

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

ʻO nā fibroblasts ma waenakonu o ke kiʻi nā fibroblasts, a ʻo ka pūnaewele spider a puni lākou he collagen. Hoʻokumu ʻia ʻo Collagen e nā fibroblasts, a ʻo ka ʻili ʻōpio he ʻekolu-dimensional a paʻa paʻa i ka collagen pūnaewele, me nā fibroblasts e huki ikaika ana i nā kolagen fibers e hāʻawi i ka ʻili ʻōpio i kahi ʻano piha a maʻalahi.

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

Ma waho aʻe o ka nānā nui ʻana i ka sunscreen, hiki iā mākou ke hoʻohana i kekahi me ka huaora A, ka huaora E, ka ferulic acid, resveratrol a me nā mea ʻē aʻe o nā huahana mālama ʻili; Hiki ke ʻai i nā huaʻai a me nā lau ʻulaʻula ʻē aʻe, e like me nā ʻōmato, nui nā ʻōmato i ka lycopene.

Hiki iā ia ke hoʻopaʻa maikaʻi i ka oxygen a pale i ke koʻikoʻi oxidative, hiki iā ʻoe ke ʻai hou aku i ka broccoli, aia ka broccoli i kahi mea i kapa ʻia ʻo glycosides ʻaila sinapi, ma hope o ka ʻai ʻana o kēia mea hoʻohui, e mālama ʻia lākou i loko o ka ʻili, i hiki i nā ʻili ʻili ke pale iā lākou iho. , hiki i kēia mau huaʻai a me nā huaʻai ke hoʻoikaika i ka pale ʻana o ka cell i ka ʻelemakule.

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

ʻili glycation

ʻO ka Glycation, ma nā ʻōlelo ʻoihana, ua kapa ʻia ʻo ka non-enzymatic glycosylation reaction a i ʻole ka hopena Melad. ʻO ke kumumanaʻo, ʻo ka hoʻohaʻahaʻa ʻana i nā sugars e hoʻopaʻa i nā protein i ka nele o nā enzymes; ʻO ka hoʻohaʻahaʻa sugars hiki ke hoʻohuli ʻia me nā protein, a ʻo ka hoʻohaʻahaʻa ʻana i nā sugars a me nā protein e loaʻa i kahi oxidation lōʻihi, dehydrogenation, a me ka hoʻoponopono hou ʻana, ka hopena i ka hana ʻana i nā huahana hope loa glycosylation, a i ʻole AGEs no ka pōkole.

ʻO nā AGEs he pūʻulu o nā ʻōpala olaola pili ʻole, ʻeleʻele-ʻeleʻele, ʻaʻole makaʻu i ka luku ʻana i ka enzyme, a ʻo ia kekahi o nā kumu nui o ka ʻelemakule kanaka. I ko mākou mau makahiki, hōʻuluʻulu ʻo AGEs i ke kino, e alakaʻi ana i ka hoʻonui ʻana i ka paʻakikī o nā paia o loko o nā kīʻaha koko, kahi kaulike ʻole o ka metabolism o ka iwi e alakaʻi ai i ka osteoporosis, a me ka luku ʻana o ka collagen a me ka elastin fibers i nā dermis e alakaʻi ana i ka ʻelemakule. Ua hōʻuluʻulu ʻia ka ʻelemakule o ka ʻili ma muli o ka glycation i hoʻokahi huaʻōlelo: hoʻopau ke kō i nā protein olakino a hoʻololi i nā ʻōnaehana ʻōpiopio i loko o nā hale protein kahiko, e alakaʻi ana i ka ʻelemakule a me ka nalowale o ka elasticity o ka collagen a me nā fiber elastic i loko o ka dermis.
