Derived from bearberry leaves, alpha-arbutin is known for its lightening properties. It is a molecule that inhibits the synthesis of melanin at non-cytotoxic concentrations by blocking the activity of the tyrosinase enzyme in the skin, which is responsible for the formation of pigmentation spots. On the other hand, arbutin acid is also a urinary and intestinal antiseptic on colibacilli, germs responsible for urinary infections.
