These Kd values are in good agreement with the reported IC50app and values for arbutin ranging from 0.37 mM to 8.4 mM [6,23,6466], acting as inhibitor of different substrates. It can also produce hyperpigmentation disorders such as ephelide, freckles, solar lentigines and melasma [2], which are treated with inhibitors of tyrosinase [24]. In conclusion, combining both alpha arbutin with retinol is a good idea because it will give you a more consistent result. It is involved in the production of melanin, which causes pigmentation of the skin, protecting it from UV-induced damage. Group of Molecular Interactions in Membranes, Department of Biochemistry and Molecular Biology-A, University of Murcia, Espinardo, Murcia, Spain. Arbutin doesnt permanently lighten or bleach skin.

Three repetitions of each experiment were made. Alpha Arbutin Benefits for Skin and How to Use It - Dr. Axe Applied topically, it inhibits tyrosinase and thus prevents the formation of melanin. In this work, we demonstrate that the oxy form of tyrosinase (oxytyrosinase) hydroxylates and -arbutin in ortho position of the phenolic hydroxyl group, giving rise to a complex formed by met-tyrosinase with the hydroxylated or .

Though alpha arbutin is more expensive, it takes less quantity to achieve better whitening effects. What Is Alpha Arbutin & How Does It Affect Skin? Experts Explain This complex could evolve in two ways: by oxidizing the originated o-diphenol to o-quinone and deoxy-tyrosinase, or by delivering the o-diphenol and met-tyrosinase to the medium, which would produce the self-activation of the system.
