Does anyone know any products in the USA tha contain "Deoxyarbutin"? And did it work for you?How many shades, or just lightens dark spots?
I already have found out that Deoxyarbutin and Benzylarbutin are several times stronger than regular Arbutin (regular Bearberry extract) and that Alpha-Arbutin and Methyl-arbutin as not as strong as them. Are there any others?
