Arbutin e ka ntšoa ka tlhaho ho limela tse kang bearberry mme e entsoe ka mokhoa oa lik'hemik'hale. Synthesized Arbutin hajoale ke e 'ngoe ea li-hypopigmenting tse sebelisoang haholo litlolong. Arbutin e ka boela ea kolobisa letlalo le shebahalang le le bobebe haholo, kahoo arbutin e sebelisoa ho khantša letlalo le ho soeufatsa litlolo.
Arbutin e kenyelletsa Alpha-Arbutin le Beta-Arbutin. Bakeng sa tlhaiso-leseling e batsi ka sehlahisoa, o ka etela sehokela: /alpha-arbutin-product/

Arbutin ke glycosylated hydroquinone e tlang ka mefuta e 'meli, Alpha-Arbutin le Beta-Arbutin. Arbutins e nkuoa e le ntho e loketseng ho khantša letlalo kaha e thusa ho thibela epidermal melanin biosynthesis. E thusa ho thibela epidermal melanin biosynthesis ka ho thibela enzymatic oxidation ea Tyrosine le Dopa.

Hydroquinone vs Alpha Arbutin
Hydroquinone esale e nkuoa e le tekanyetso ea khauta bakeng sa kalafo ea hyperpigmentation. Leha liphuputso tsa bongaka li tlaleha karabelo e ntle ea depigmentation e hlahisitsoeng ke 2% hydroquinone, e boetse e bonts'itsoe e baka litlamorao tse sa foleng. Tsena li kenyeletsa exogenous ochronosis, cataract, pigmented colloid milia, sclera, le pigmentation ea manala, ho lahleheloa ke letlalo la letlalo, ho fola ha maqeba le ho ntša monko o khopisang oa tlhapi. Hydroquinone le eona e ka baka tšenyo ea DNA. Litlamorao tsena tse mpe li fokotsa tšebeliso ea hydroquinone.
Ho netefalitsoe hore Alpha-Arbutin e na le phello e khanyang ntle le chefo le likhohlano tse amanang le hydroquinone.
