Ua kūpono ʻo Arbutin no ka hoʻohana ʻana i ke ao

ʻO Arbutin, ka mea i kapa ʻia ʻo myricetin, he mea hana keʻokeʻo ʻili e hoʻohui i nā manaʻo o ka "'ōmaʻomaʻo", "palekana", a me ka "maikaʻi" no ka mea mai nā mea kanu ʻōmaʻomaʻo maoli. ʻO Arbutin kahi mea hana keʻokeʻo kūpono no ka hoʻomaʻemaʻe ʻana i nā mea hoʻonaninani, me ʻelua isomers optical, ʻo ia hoʻi ʻo α "A" "type, me ka hana biological ka" "isomer." ". He pauda melemele iki keʻokeʻo ma ka lumi wela, hiki ke hoʻoheheʻe ʻia i ka wai, a hoʻohui ʻia i nā huahana keʻokeʻo a me ka mālama ʻana.

ʻO ka pauka Arbutin kekahi o nā mea keʻokeʻo palekana palekana a maikaʻi hoʻi i kaulana i kēia manawa ma waho, a ʻo ia hoʻi ka mea hoʻokūkū hoʻokūkū ʻili a me ka freckle removing agent active i ka 21st century. I loko o nā mea hoʻonaninani, hiki iā ia ke hoʻomaʻemaʻe maikaʻi a wehe i nā freckles ma ka ʻili, e mae mālie a wehe i nā freckles, chloasma, melanosis, acne, a me nā kiko makahiki. Palekana kiʻekiʻe, ʻaʻohe huhū, sensitization, a me nā hopena ʻaoʻao ʻē aʻe. I mea e hoʻokūpaʻa ai i ka hana, hoʻohui pinepine ʻia ka nui o nā antioxidants e like me ka sodium bisulfite a me ka huaora E no ka hoʻokō ʻana i ka keʻokeʻo maikaʻi, ka wehe ʻana i ka freckle, ka moisturizing, ka palupalu, ka wehe ʻana i ka wrinkle, a me nā hopena anti-inflammatory. Hiki ke hoʻohana ʻia e hoʻopau i ka ʻulaʻula a me ka pehu ʻana, e hoʻoikaika i ka hoʻōla ʻana i ka ʻeha me ka waiho ʻole ʻana i nā ʻōpala, a ke kāohi i ka hoʻokumu ʻana o ka dandruff.

ʻElua mau ʻano o ka pauka Arbutin: alpha arbutin pauka a me beta arbutin pauka.

(1). ʻOkoʻa loa nā kumu o α- Arbutin a me β- arbutin.

Hiki ke unuhi ʻia ka β- Arbutin mai nā mea kanu ma o ka moʻomeheu cell a me ka synthesis artificial, ka hoʻololi ʻana i ka enzyme, a me ka unuhi ʻana i nā mea kanu.

Hiki i ka α- Arbutin ke hoʻololi wale i ka hoʻololi kōpaʻa ma o nā enzymes o nā microorganism like ʻole, e ʻae ana i hoʻokahi mole o ka glucose a me hoʻokahi mole o ka hydroquinone e hui i hoʻokahi α-Arbutin. ʻO ke kūpaʻa kiʻekiʻe, ka pono, a me ka palekana β- Arbutin.

(2). α- ʻO ke kumukūʻai o arbutin he β- Ma kahi o 8 mau manawa e like me ka arbutin.

(3). α- ʻO ka hopena keʻokeʻo o ka arbutin he β- ʻoi aku ma mua o 15 mau manawa e like me ka arbutin.

(4). ʻOi aku ka ikaika o ka α-Arbutin i ka hana tyrosinase.

(5). ʻOi aku ka paʻa o α Ursolin, ʻaʻole decompose ʻo α Arbutin i kahi mahana kiʻekiʻe o 100 ° C; β Arbutin decompose iki ma luna o 60 ° C.

(6). α- ʻAʻole paʻi kiʻi ʻo Arbutin a hiki ke hoʻohana ʻia i ka lā.

(7). ʻAʻole loaʻa ʻo Arbutin i ke ʻano a hiki ke loaʻa wale ma o ka fermentation.

(8). Ua hoʻohana ʻia ʻo β- Arbutin i ka mākeke no ka manawa lōʻihi, no laila ʻo ka arbutin maʻamau ʻo β- Arbutin ma kahi o α- Arbutin.

Arbutin ho'ēmi i ka hana o ka melanin ma ka inhibiting i ka hana o ka enzyme tyrosinase i produces melanin, a me kona 'ano o ka hana e like me ka whitening laau hydroquinone.Arbutin ua oi aku ka glucose molecules i loko o kona hale ma mua o hydroquinone, i emi irritating a hiki. e hoʻohui manuahi ʻia i nā huahana mālama me ka palena o ka manaʻo a hiki i 7%.

Hiki i ka mole mole o arbutin ke komo i ka papa basal no ka wehe ʻana i kahi hohonu, a he hopena therapeutic koʻikoʻi i ka chloasma, nā ʻeleʻele, ka sunburn, a me ka pigmentation i koe mai nā allergies lāʻau. Eia naʻe, inā haʻahaʻa loa ka ʻike, e nāwaliwali ka hoʻomau ʻana o kāna hopena. No laila, ʻo ka neʻe ʻana o 5% ka mea palekana a maikaʻi loa hoʻi ka hoʻoneʻe ʻana i kahi kiko, a ʻoi aku ka wikiwiki o ka 5% ma mua o ka huaora C no ka wehe ʻana i kahi kiko. Eia kekahi, paʻa ka hoʻomau ʻana o ka wehe ʻana i ka wahi, a ʻaʻohe hopena hoʻoulu i ka ʻili.

Ma hope o ka hoʻopili ʻia ʻana e ka ʻili, e hoʻemi ʻia ka arbutin i hydroquinone, kahi i kānalua ai kekahi poʻe i ka palekana o ka arbutin a manaʻoʻiʻo e loaʻa ana i ka arbutin ka manawa e hana ai i nā hopena ʻaoʻao e like me ka hydroquinone. ʻO ka ʻōlelo maʻamau i lohe ʻia ʻo ia "ʻaʻole pono e hoʻohana ʻia nā huahana mālama i loaʻa i ka arbutin i ka lā, inā ʻaʻole lākou e keʻokeʻo a lilo i ʻeleʻele."

Ua hōʻike ʻia nā hoʻokolohua ʻo ka arbutin wale nō me ka manaʻo i ʻoi aku ma mua o 7% hiki ke lilo i photosensitive, no laila ʻo 7% kahi paepae palekana. ʻO ka hoʻohui ʻana i nā mea i loko o nā huahana mālama i nā lula maʻemaʻe, a ʻo ka palena kiʻekiʻe loa he 7%. I loko o kēia pae hoʻonaʻauao, ʻaʻole lawa ka arbutin e hana i ka photosensitivity, a ʻaʻole pono e hoʻohana iā ia ma kahi pouli. Hoʻopili ʻia i loko o ka ʻili a decomposed e ka mālamalama, e hoʻemi ʻia i ka hydroquinone, e hana ana i kahi hopena keʻokeʻo.
