It's true. While wrinkles can of course make you look old, it's a fact that age spots can make you look even older. "Liver spots" (flat brown spots on the skin) don't really have anything to do with the liver. Instead, they're an almost universal sign of aging and sun exposure. They occur mainly on the hands, face and chest and tend to darken over time.
RevivSerums.com has two great solutions for age spots. Our Phloretin Serum with Ferulic and Lipoic Acid works great on spots, especially during daytime sun exposure. And our Ultimate Serum is indeed the ultimate for a clear, even complexion and superbly healthy skin. Alpha Arbutin is one of its ingredients which inhibits tyrosinase and thus prevents the formation of melanin. It acts similarly to hydroquinone (in fact it's a "glycosylated hydroquinone" extracted from the bearberry plant) but it's a natural alternative without the side effects. It's also an expensive ingredient, but it's worth it.
While any of those three great products can significantly reduce or even eliminate age spots, the best prevention is to stay out of the sun and wear a physical sunscreen when you are in the sun. At least SPF 30.
