●Nei Muviri Wemunhu Uchigadzira Melanin?
Kubuda kwezuva ndicho chikonzero chikuru chekugadzirwa kwe melanin. Ultraviolet mwaranzi muchiedza chezuva inokuvadza deoxyribonucleic acid, kana DNA, mumaseru. DNA yakakuvadzwa inogona kutungamira mukukuvadzwa uye kubviswa kweruzivo rwemajini, uye kutokonzeresa kushanduka kwemajini, kana kurasikirwa kwebundu suppressor genes, zvichikonzera kuitika kwemamota.
Zvisinei, kuratidzwa kwezuva hakusi "kunotyisa", uye izvi zvose "chikwereti" kune melanin. Muchokwadi, panguva dzakaoma, melanin ichaburitswa, inonyatso kutora simba re ultraviolet rays, kudzivirira DNA kubva pakukuvadzwa, nokudaro kuderedza kukuvadzwa kunokonzerwa nemirairo ye ultraviolet kumuviri wemunhu. Kunyangwe melanin ichidzivirira muviri wemunhu kubva mukukuvara kwe ultraviolet, inogonawo kuita kuti ganda redu rive rima uye kugadzira makwapa. Naizvozvo, kudzivirira kugadzirwa kwe melanin inzira yakakosha yekuchena kweganda muindasitiri yekunaka.
● ChiiArbutin?
Arbutin, inozivikanwawo se arbutin, ine kemikari formula yeC12H16O7. Icho chinhu chinotorwa kubva pamashizha eEricaceae plant bearberry.

Ivo vese vane mhedzisiro yekudzivisa tyrosinase kuwana chena. Inonyanya kushandiswa ndeye β-mhando, iyo yakachipa. Zvisinei, maererano nekutsvakurudza, kuwedzera α-mhando yakaenzana ne1/9 yehuwandu hwe-β-mhando inogona kudzivisa kugadzirwa kwetyrosinase uye kubudirira kuchena. Zvigadzirwa zvakawanda zvekuchengetedza ganda zvine yakawedzera α-arbutin zvine chena mhedzisiro yakapetwa kagumi kupfuura yechinyakare arbutin.
●Zvii ZvakanakiraArbutin?
Arbutin inonyanya kutorwa kubva pamashizha ebearberry. Inogonawo kuwanikwa mune mimwe michero nemimwe miti. Iine simba rekuvhenekera ganda. Inogona kukurumidza kupinda mukati meganda pasina kukanganisa masero eganda. Inobatanidza ne tyrosine, iyo inokonzera kugadzirwa kwe melanin, uye inogona kunyatsovhara basa re tyrosinase uye kugadzirwa kwe melanin, kukurumidza kuora uye kubviswa kwe melanin. Mukuwedzera, arbutin inogona kudzivirira ganda kubva kune mahara radicals uye ine yakanaka hydrophilicity. Nokudaro, inowanzowedzerwa kune zvigadzirwa zvekuchena pamusika, kunyanya munyika dzeAsia.
Arbutinchinhu chakasikwa chinoshanda chinobva mumiti yakasvibira. Icho chikamu cheganda decolorizing chinosanganisa "miti yakasvibira, yakachengeteka uye yakavimbika" uye "inoshanda decolorization". Inogona kukurumidza kupinda mukati meganda. Pasina kukanganisa kupararira kwesero, inogona kunyatso kuvharidzira basa re tyrosinase muganda uye kuvhara kuumbwa kwe melanin. Nokubatanidza zvakananga ne tyrosinase, inokurumidza kuora uye kubuda kwe melanin, nokudaro kuderedza ruvara rweganda, kubvisa mavara uye freckles, uye haina chepfu, inogumbura, inokurudzira uye mamwe migumisiro pa melanocytes. Iyo inewo bactericidal uye anti-inflammatory effects. Ndiyo yakachengeteka uye inoshanda zvakanyanya kuchena chena zvinhu zvakakurumbira nhasi, uye zvakare yakanakira kuchena kweganda uye freckle inoshanda mumiriri muzana ramakore re21.
●Chii Chinonyanya KushandiswaArbutin?
Inogona kushandiswa muzvigadzirwa zvepamusoro-soro uye inogona kugadzirwa kuva ganda rekuchengetedza cream, freckle cream, high-end pearl cream, etc. Haigoni kungoshongedza uye kudzivirira ganda, asiwo kuva anti-inflammatory uye anti-irritant.
