Tyrosinase is an enzyme[1] held in the skin of mammals. It is the only enzyme absolutely required for melanin[2] production.
The more active the tyrosinase, the more melanin production. This is good for our natural skin color. In fact, the condition of albinism is caused by a lack of tyrosinase.
It’s also nice when tanning. However, as the skin damages from the effects of the sun or hormones then skin coloring becomes uneven. We get “age spots”. In fact, UV-exposure can increase melanin and thus tyrosinase activity up to 100 fold.
Bottom line, by inhibiting the tyrosinase the signs of sun damage in the form of discolored skin can be reversed.
Products to look for that are good tyrosinase inhibitors are: Arbutin, Vitamin C, Kojic Acid, Licorice Extract, Scutellaria Extract, Mulberry Extract, Burner Root Extract, and Melanostat in addition to peeling actions of Glycolic Acid, Alpha/Beta Hydroxy Acids, and Retinol.
AND, most of all protect yourself from UV rays.
