Arbutin inogona kutorwa pachisikigo kubva muzvirimwa zvakaita sebereberry uye kugadzirwa nemakemikari nzira. Synthesized Arbutin parizvino ndeimwe yeanonyanya kushandiswa hypopigmenting ejenti muzvizoro. Arbutin inogona zvakare kunyorovesa ganda rinotaridzika kupenya zvakanyanya, saka arbutin inoshandiswa kupenya kweganda uye kuchena maejenti muzvizoro.
Arbutin inosanganisira Alpha-Arbutin uye Beta-Arbutin. Kuti uwane ruzivo rwakadzama rwechigadzirwa, unogona kushanyira chinongedzo: /alpha-arbutin-chigadzirwa/

Zvinokonzera pigmentation:
Rudzi rweganda rinosarudzwa nekubatana kwemavara akasiyana. Ruvara rwebrown runobva kune pigments eumelanin uye phaeomelanin, iyo inogadzirwa mumasero epidermal akakosha anonzi melanocytes. Iyo enzyme tyrosinase, inowanzovapo mune isingashande fomu, inoumbwa mune aya melanocytes. Kuitwa kwayo neUV mwenje kunokonzeresa melanogenesis, akaomesesa akateedzana enzymatic kemikari maitiro ayo anozopedzisira atungamira mukuumbwa kwema melanin, zvichitungamira kune kusingade kushanduka kweganda pamusoro peganda iro rinowanzo ratidza sezera remavara, melasma kana freckles.
Mechanism of Action:
Arbutin is glycosylated hydroquinone iyo inouya mu 2 mafomu, iyo Alpha-Arbutin uye iyo Beta-Arbutin. Arbutins inoonekwa seyakanakira ganda rekuvhenekesa ganda sezvo ichibatsira mukuvhara epidermal melanin biosynthesis. Inobatsira kuvhara epidermal melanin biosynthesis nekudzivisa enzymatic oxidation yeTyrosine neDopa.
Alpha-Arbutin yakaratidza kuve nemhedzisiro yepamusoro, kunyangwe ichienzaniswa nemakemikari-akafanana mamorekuru, hydroquinone uye beta-arbutin. Pamusoro pekushanda kwepamusoro, inozvirumbidza nekuchengetedza zvirinani zvichienzaniswa nehydroquinone, uye yakagadzikana kana ichienzaniswa nebeta-arbutin. Hunhu uhwu hunoita kuti ive yekuenda-kushanda kupenya kweganda uye kuderedza makwapa akasviba paganda.
Hydroquinone vs Alpha Arbutin
Hydroquinone yagara ichionekwa seyegoridhe chiyero chekurapa hyperpigmentation. Nepo zvidzidzo zvekiriniki zvichitaura zvakanakisa depigmentation mhinduro dzakakonzerwa ne2% hydroquinone, zvakaratidzwawo kukonzera zvisingaperi mhedzisiro yakaipa. Izvi zvinosanganisira exogenous ochronosis, cataract, pigmented colloid milia, sclera, uye pigmentation yezvipikiri, kurasikirwa kwekusimba kweganda, kukanganiswa kupora kweronda uye kuburitsa hwema hwehove hunonyangadza. Hydroquinone inogonawo kukonzera kukuvara kweDNA. Izvi zvakashata zvinokanganisa kushandiswa kwehydroquinone.
Alpha-Arbutin yakaratidza kuti inogadzira yakanyanya kupenya mhedzisiro isina muchetura uye kushatirwa kwakabatana nehydroquinone.
Zvigadzirwa zvekuchengetedza ganda zvine arbutin:Ganda Cream, Freckle Cream, Superior Pearl Cream uye Facial Mask.
