●No ke aha e hana ai ke kino kanaka i ka melanin?
ʻO ka ʻike ʻana i ka lā ke kumu nui o ka hana melanin. ʻO nā kukuna Ultraviolet i ka lā e hōʻino i ka deoxyribonucleic acid, a i ʻole DNA, i loko o nā cell. Hiki i ka DNA pōʻino ke alakaʻi i ka pōʻino a me ka wehe ʻana o ka ʻike genetic, a hiki i ke kumu o ka hoʻololi ʻana i nā ʻano genes malignant, a i ʻole ka nalo ʻana o nā genes suppressor tumor, e alakaʻi ana i ka hiki ʻana o nā maʻi koko.
Eia naʻe, ʻaʻole "weliweli" ka ʻike ʻana o ka lā, a ʻo kēia ka "hōʻaiʻē" i ka melanin. ʻO kaʻoiaʻiʻo, i nā manawa koʻikoʻi, e hoʻokuʻu ʻia ka melanin, e hoʻomoʻi pono i ka ikehu o nā kukuna ultraviolet, e pale ana i ka hōʻino ʻana o DNA, a laila e hōʻemi i ka pōʻino i hana ʻia e nā kukuna ultraviolet i ke kino o ke kanaka. ʻOiai ke pale nei ka melanin i ke kino o ke kanaka mai ka pōʻino ultraviolet, hiki iā ia ke hoʻopōʻeleʻele i ko mākou ʻili a hoʻomohala i nā kiko. No laila, ʻo ka pale ʻana i ka hana ʻana o ka melanin he mea nui ia o ka keʻokeʻo ʻili i ka ʻoihana nani.
●He aha iaArbutin?
ʻO Arbutin, ka mea i kapa ʻia ʻo arbutin, loaʻa kahi ʻano kemika o C12H16O7. He mea ia i lawe ʻia mai nā lau o ka mea kanu ʻo Ericaceae bearberry. Hiki iā ia ke pale i ka hana o tyrosinase i loko o ke kino a pale i ka hana ʻana o ka melanin, a laila e hōʻemi i ka pigmentation ʻili, wehe i nā kiko a me nā freckles. Loaʻa iā ia nā hopena bactericidal a me nā anti-inflammatory a hoʻohana nui ʻia i nā mea hoʻonaninani.
Arbutinhiki ke hoʻokaʻawale ʻia i α-type a me β-type e like me nā hale like ʻole. ʻO ka ʻokoʻa nui loa ma waena o nā mea ʻelua i nā waiwai kino, ʻo ia ka rotation optical: ʻo α-arbutin ma kahi o 180 degere, aʻo β-arbutin ma kahi o -60. Loaʻa iā lāua ʻelua ka hopena o ke kāohi ʻana i ka tyrosinase e hoʻokō i ka keʻokeʻo. ʻO ka mea i hoʻohana nui ʻia he β-type, ʻo ia ka mea maʻalahi. Eia nō naʻe, e like me ka noiʻi, hoʻohui i ka α-type e like me 1/9 o ka neʻe ʻana o ka β-type hiki ke kāohi i ka hana ʻana o tyrosinase a loaʻa ka whitening. Nui nā huahana mālama ʻili me ka α-arbutin i hoʻohui ʻia he ʻumi mau manawa kiʻekiʻe ma mua o ka arbutin kuʻuna.
●He aha nā pono oArbutin?
Lawe ʻia ʻo Arbutin mai nā lau o ka bearberry. Hiki ke loaʻa ma kekahi mau huaʻai a me nā mea kanu ʻē aʻe. Loaʻa iā ia ka hopena o ka hoʻomālamalama ʻana i ka ʻili. Hiki iā ia ke komo koke i loko o ka ʻili me ka ʻole o ka pili ʻana i nā ʻili ʻili. Hoʻohui ia me ka tyrosine, ka mea e hana ai i ka melanin, a hiki ke hoʻopaʻa pono i ka hana o tyrosinase a me ka hana ʻana o ka melanin, e wikiwiki ana i ka decomposition a me ka hoʻopau ʻana i ka melanin. Eia kekahi, hiki i ka arbutin ke pale i ka ʻili mai nā radical manuahi a loaʻa ka hydrophilicity maikaʻi. No laila, hoʻohui pinepine ʻia i nā huahana keʻokeʻo ma ka mākeke, ʻoi aku hoʻi ma nā ʻāina ʻĀsia.
Arbutinhe mea ʻeleu maoli i loaʻa mai nā mea kanu ʻōmaʻomaʻo. ʻO ia kahi ʻāpana decolorizing ʻili e hoʻohui i nā "mea kanu ʻōmaʻomaʻo, palekana a hilinaʻi" a me ka "decolorization kūpono". Hiki ke komo koke i loko o ka ʻili. Me ka ʻole o ka pili ʻana i ka hoʻonui ʻana o ka cell, hiki iā ia ke pale pono i ka hana o tyrosinase i ka ʻili a pale i ka hoʻokumu ʻana o ka melanin. Ma ka hui pū ʻana me ka tyrosinase, hoʻolalelale ia i ka decomposition a me ka excretion o ka melanin, a laila e hōʻemi ana i ka pigmentation o ka ʻili, wehe i nā kiko a me nā freckles, a ʻaʻohe mea ʻawaʻawa, hoʻonāukiuki, sensitizing a me nā hopena ʻē aʻe ma nā melanocytes. Loaʻa iā ia nā hopena bactericidal a me nā anti-inflammatory. ʻO ia ka mea palekana a ʻoi aku ka maikaʻi o ka mea keʻokeʻo keʻokeʻo i kaulana i kēia mau lā, a he mea hoʻomaʻemaʻe ʻili maikaʻi a me ka freckle active agent i ka 21st century.
●He aha ka hoʻohana nui oArbutin?
Hiki ke hoʻohanaʻia i nā mea hoʻonani kiʻekiʻe a hiki ke hanaʻia i kaʻili mālamaʻili, freckle cream, high-end pearl cream, a me nā mea'ē aʻe.
ʻO nā mea waiwai no ka lāʻau kuni a me ka maʻi ʻeha: ʻO Arbutin ka mea nui o ka lāʻau hou a me ka lāʻau lapaʻau, kahi i hōʻike ʻia e ka wikiwiki o ka ʻeha, ka hopena anti-inflammatory ikaika, ka hoʻopau wikiwiki ʻana i ka ʻulaʻula a me ka pehu, ka hoʻōla wikiwiki ʻana, ʻaʻohe ʻōpala.
ʻO ke ʻano o ka hoʻopaʻa ʻana: kāpī a hoʻopili paha.
ʻO nā mea waiwai no ka lāʻau anti-inflammatory o ka ʻōpū: maikaʻi bactericidal a me nā hopena anti-inflammatory, ʻaʻohe hopena ʻino.
