Arbutin is a new type of skin de-coloring and whitening agents, an extract of Bearberry plant which produced by a solid or liquid extraction, it is also an friendly process.

Arbutin protect the skin against damage caused by basic Prolems.Arbutin inhibits the formation of melanin pigment by restraining Tyrosinase activity.

The target of Melanostat the membrane receptor of alpha-MSH on the melanocytes, the B- MICR receptor , its mode of action is a competitive inhibition of alpha-MSH, membrane receptors are blocked in a natural way.
