Oh no! Old age?

I know I get paranoid about growing old. Even though I have quite a few years before I reach "old age," I freak out just a little every time I see a new spot on my skin. Is it a freckle? Is it an old age spot? EEK! I wonder if there's some sort of age spot removal cream or something I could use now to keep spots at bay. I don't want to look like a little old lady!
