Cosmetic Ingredient Alpha Arbutin

Arbutin exists in two conformations, alpha and beta. The alpha conformation offers higher stability and is the preferred form for skin lightening applications. This is the purest and most effective form of arbutin (especially when compared to beta arbutin). It's a powerful skin lightener and works on all skin types. Alpha arbutin is expensive to manufacture which is why usually only high quality products contain this ingredient. Watch our for cheap products which claim to contain "arbutin" but formulate it in the beta formulation. In addition Alpha arbutin is also more stable than Beta arbutin. 

Medical studies have shown it to be effective for skin lightening. There are patents covering its use for topical skin lightening products. Alpha-Arbutin doesn't appear to have any nasty side effects and government studies have shown it to be safe to use.
