Imikorere no Gushyira mu bikorwa
1. Ingaruka yera: Alpha Arbutin ifatwa nkibikoresho byera cyane. Irashobora guhagarika ibikorwa bya tyrosinase, kugabanya imiterere ya melanine no kugabanuka, kandi ikorohereza neza ibibazo byuruhu rwuruhu nkibibara byijimye, ibibyimba nizuba. Muri icyo gihe, iringaniza imiterere yuruhu kandi ikanagaragaza uruhu rwijimye.
2. Kubuza umusaruro wa melanin: Alpha arbutin irashobora kubangamira inzira ya synthesis ya melanin, ikabuza ibikorwa bya okiside ya tirozine, kandi ikabuza gukora melanine. Ibi bituma iba ibikoresho byiza byo kuvura uruhu bibuza umusaruro mwinshi wa melanine, bikagabanya ibyago byo hyperpigmentation no kwibeshya.
3. Umutekano n’umutekano: Ugereranije nibindi bintu byera, Alpha Arbutin ifite umutekano n’umutekano mwinshi. Ntabwo izatakaza ibikorwa byayo kubera urumuri cyangwa okiside, kandi irashobora gukomeza ingaruka zayo zo kwera igihe kirekire. Byongeye kandi, alpha arbutin yerekana uburakari buke kuruhu kandi ikwiranye nubwoko bwose bwuruhu.
4. Kuvomera no kurwanya okiside: Usibye ingaruka zera, alpha arbutin ifite n'ingaruka zo kurwanya no kurwanya okiside. Irashobora kongera ubuhehere buri muri stratum corneum, igahindura uburinganire bwuruhu rwuruhu, kandi igabanya neza gukama no gukomera kwuruhu. Muri icyo gihe, itesha agaciro radicals yubuntu, ikarinda imbaraga za okiside, kandi ikarinda uruhu kwangiza ibidukikije.
