Arbutin, eke na-acha ?cha na-ar? ?r? bekee

Arbutin b? ogige hydroquinone glycoside, aha kem?kal ya b? 4-Hydroquinone-alpha-D-glucopyranoside (4-Hydroquinone-alpha-D-glucopyranoside), nke d? na osisi nd? d? ka bearberry na bilberry. ? b? ihe na-ar? ?r? na-acha ?cha eke na-ap?ta site na Chemicalbook nke na-ad?gh? ewe iwe, na-ad?gh? ah? efe na dak?tara. Enwere otu ab?? na-ar? ?r? na-ar? ?r? na nhazi nke arbutin: otu b? glucose f?d?r?n?; nke ?z? b? phenolic hydroxyl otu. ?n?d? an? ah? nke α-arbutin na-acha ?cha na nt? nt? nt? nt?, nke na-ad? ngwa ngwa na mmiri na ethanol.

1. Mmet?ta na-acha ?cha: A na-ewere Alfa Arbutin ka ? b?r? ihe na-acha ?cha nke ?ma. ? nwere ike igbochi ?r? tyrosinase, belata nhazi na ntinye nke melanin, ma mee ka nsogbu akp?kp? an? d? ka nt?p? gbara ?ch?ch?r?, nt?p? na nt?p? anyanw?. N'otu oge ah?, ? na-eme ka ?da akp?kp? ah? p?ta ìhè ma na-egbuke egbuke akp?kp? an?.

2. Na-egbochi mmep?ta melanin: Alfa arbutin nwere ike igbochi usoro njik? nke melanin, gbochie ?r? oxidase nke tyrosine, ma gbochie mmep?ta nke melanin. Nke a na-eme ka ? b?r? ihe nlek?ta an? ah? d? mma nke na-egbochi mmep?ta nke melanin, na-ebelata ihe ize nd? nke hyperpigmentation na nt?p?.

3. Nchekwa na nkw?si ike: E jiri ya t?nyere ihe nd? ?z? na-acha ?cha, Alpha Arbutin nwere nchekwa d? elu na nkw?si ike. ? gagh? at?fu ?r? ya n'ihi ìhè ma ? b? oxidation, ma nwee ike ?n?gide na-enwe mmet?ta ?cha ya ruo ogologo oge. Na mgbakwunye, alfa arbutin na-egosip?ta obere mgbakas? ah? na akp?kp? ah? dabara adaba maka ?d? an? ah? niile.

4. Moisturizing na mgbochi oxidation: Na mgbakwunye na mmet?ta na-acha ?cha, alfa arbutin nwekwara mmet?ta moisturizing na mgbochi oxidation. ? nwere ike ?bawanye ?d?naya mmiri nke stratum corneum, melite nguzozi mmiri nke akp?kp? ah?, ma na-ebelata nk? na nchichi nke akp?kp? ah? nke ?ma. N'otu oge ah?, ? na-ewep? free radicals, na-echebe megide nr?gide oxidative, na-echebe akp?kp? ah? p?? na mmebi gburugburu ebe obibi.
