Hyperpigmentation – or the darkening of an area of the skin – can be caused by sun damage, acne, inflammation, and other skin injuries that increase the production of melanin. Tyrosinase is an enzyme that helps regulate melanin; if tyrosinase is not functioning properly in the body, it allows melanin to increase unchecked. This can result in dark circles under the eyes, liver spots, and other patches of discolored skin.
Studies have shown that cocoa pods can inhibit tyrosinase activity, resulting in lighter skin tones. It also has the ability to naturally absorb UV light, offering some added protection from sun damage that causes dark spots to form in the first place.
