Beta Arbutin - This form of arbutin is often referred to as just "arbutin" so if you don't see the ingredient list specifying the Alpha component then you can assume it's probably in the beta formulation. This formulation is cheaper to produce and manufacture and is not as effective as alpha arbutin. Newer skin products contain alpha arbutin while older cosmetic products contain either "beta arbutin" or simply "arbutin".
