The tree, commonly known as a madrone, is also referred to as the strawberry tree because of the berry’s resemblance to strawberries (though they are not related plants).

Studies also demonstrate that Arbutus unedo fruit extract is a tyrosinase inhibitor, meaning it impacts the effect of tyrosinase, an enzyme that plays a role in skin discolorations.
