It really depends on what you think is causing these marks. It can also be caused by over exposure to sun for instance and not only aging. Try staying out of the sun and continue using a moisturizer. I hear that cocao butter is pretty good!

That is something that I  fear may happen to my face as I get older. What causes age spots and how can it be prevented?

You could use a topical skin tone smoother, sort of like a skin lightener, but it works to fade age spots specifically. Also, try using soaps with kojic acid or glutathione which would have the same effect to even your skin tone.

The skin on my face is not only getting some age spots but just looks totally uneven. What can I do to help this? I moisturize regularly but will something help even out my skin tone?
