Ma ka ʻoihana nani a mālama ʻili, aia kekahi mea i aloha ʻia e nā kaikamahine a pau, a ʻo ia ka huaora C.
ʻO ka hoʻomaʻemaʻe, ka wehe ʻana i ka ʻili, a me ka nani o ka ʻili, he hopena ikaika loa ia o ka huaora C.
1, ʻO nā pōmaikaʻi nani o ka huaora C:
1) Antioxidant
Ke hoʻoulu ʻia ka ʻili e ka lā (ultraviolet radiation) a i ʻole nā pollutants kaiapuni, hana ʻia ka nui o nā radical manuahi. Ke hilinaʻi nei ka ʻili i kahi ʻōnaehana paʻakikī o ka enzyme a me nā antioxidants non-enzyme e pale iā ia iho mai ka pōʻino radical manuahi.
ʻO VC ka antioxidant nui loa i ka ʻili o ke kanaka, me ka hoʻohana ʻana i kona ʻano oxidizable e hoʻololi i nā mea ʻē aʻe a pale iā lākou mai ka oxidation. I nā huaʻōlelo ʻē aʻe, hāʻawi ʻo VC iā ia iho e hoʻopau a hoʻopau i nā radical manuahi, a laila e pale ai i ka ʻili.
2) Kāohi i ka hana melanin
Hiki i ka VC a me kāna mau mea hoʻohui ke hoʻopilikia i ka tyrosinase, hoʻemi i ka helu hoʻololi o tyrosinase, a hoʻemi i ka hana melanin. Ma waho aʻe o ka pale ʻana i ka tyrosinase, hiki i ka VC ke hana ma ke ʻano he mea hoʻohaʻahaʻa no ka melanin a me ka huahana waena o ka melanin synthesis, dopaquinone, e hōʻemi ana i ka ʻeleʻele i ke kala ʻole a loaʻa i nā hopena keʻokeʻo. ʻO ka Vitamin C he mea palekana a maikaʻi hoʻi ka ʻili keʻokeʻo.
3) Ka pale lā i ka ʻili
Hoʻokomo ʻo VC i ka synthesis o collagen a me mucopolysaccharides, hoʻoikaika i ka hoʻōla ʻana i ka ʻeha, pale i ka sunburn, a pale i ka hopena i waiho ʻia e ka nui o ka ʻike ʻana o ka lā. I ka manawa like, he waiwai antioxidant maikaʻi loa ka huaora C a hiki ke hopu a hoʻopau i nā radical manuahi i ka ʻili, e pale ana i ka pōʻino mai nā kukuna ultraviolet. No laila, kapa ʻia ka huaora C he "intradermal sunscreen". ʻOiai ʻaʻole hiki ke hoʻopaʻa a hoʻopaʻa i nā kukuna ultraviolet, hiki iā ia ke hana i kahi hopena pale i ka pōʻino ultraviolet i nā dermis. Hoʻokumu ʻia ka hopena pale o ka lā o ka hoʻohui ʻana i ka VC
4) Hoʻoikaika i ka hoʻohui ʻana o ka collagen
ʻO ka nalo ʻana o ka collagen a me ka elastin hiki ke hoʻohaʻahaʻa i ko mākou ʻili a ʻike i nā ʻano ʻelemakule e like me nā laina maikaʻi.
ʻO ka ʻokoʻa nui ma waena o ka collagen a me ka protein maʻamau ʻo ia ka hydroxyproline a me ka hydroxylysine. ʻO ka synthesis o kēia mau amino acids e pono ai ke komo ʻana o ka huaora C.
Pono ka hydroxylation o ka proline i ka synthesis o ka collagen i ke komo ʻana o ka huaora C, no laila ʻo ka hemahema o ka vitamina C e pale i ka synthesis maʻamau o ka collagen, e alakaʻi ana i nā pilikia pili pūnaewele.
5) Hoʻoponopono i nā mea pale i hoʻopau ʻia no ka hoʻōla ʻana i ka ʻeha
Hiki i ka Vitamin C ke hoʻoikaika i ka ʻokoʻa o nā keratinocytes, hoʻoulu i ka hana pale epidermal, a kōkua i ke kūkulu hou ʻana i ka papa epidermal. No laila he hopena maikaʻi loa ka vitamina C i ka pale ʻili.
ʻO ia hoʻi ke kumu o kekahi o nā hōʻailona o ka nele i kēia meaʻai, ʻo ia ka maikaʻi ʻole o ka ʻeha.
6) Anti inflammatory
Loaʻa i ka Vitamin C nā hopena antibacterial a me nā hopena anti-inflammatory, hiki ke hōʻemi i ka hana transcription factor o nā cytokine inflammatory. No laila, hoʻohana pinepine ʻia ka huaora C e nā dermatologists e mālama i nā maʻi ʻili ʻili e like me ka haki.
2， He aha nā ʻano like ʻole o ka huaora C?
Ua kapa ʻia ʻo ka huamaʻa C maʻemaʻe L-ascorbic acid (L-AA). ʻO kēia ke ʻano o ka lāʻau olaola a aʻo nui ʻia o ka huaora C. Akā naʻe, hoʻokahe koke kēia ʻano a lilo i mea ʻole ma lalo o ka ea, wela, māmā, a i ʻole nā kūlana pH koʻikoʻi. Ua hoʻopaʻa ka poʻe ʻepekema i ka L-AA ma o ka hoʻohui ʻana iā ia me ka huaora E a me ka ferulic acid no ka hoʻohana ʻana i nā mea hoʻonaninani. Nui nā ʻano kumu ʻē aʻe no ka huaora C, me ka 3-0 ethyl ascorbic acid, ascorbate glucoside, magnesium a me ka sodium ascorbate phosphate, tetrahexyl decanol ascorbate, ascorbate tetraisopropylpalmitate, a me ascorbate palmitate. ʻAʻole kēia mau derivatives he huaʻai C maʻemaʻe, akā ua hoʻololi ʻia e hoʻomaikaʻi i ke kūpaʻa a me ka hoʻomanawanui o nā molekole ascorbic acid. Ma ke ʻano o ka pono, nui ka nui o kēia mau ʻano i loaʻa i ka ʻikepili kū'ē a i ʻole e koi hou i ka noiʻi e hōʻoia i ko lākou pono. L-ascorbic acid, tetrahexyl decanol ascorbate, a me ascorbate tetraisopalmitate i hoʻopaʻa ʻia me ka huaora E a me ka waikawa ferulic ka nui o nā ʻikepili e kākoʻo ana i kā lākou hoʻohana.
