I have always been a bit skeptical about the effectiveness of primers, mainly because I don't like to wear a lot of foundation. Plus, it's just more money to spend on "un-fun" makeup. Well... that was then. Now, I've discovered that the right primer can be the difference between uneven skin texture and tone and a more fabulous, not to mention flawless, face. Plus, a primer helps keep the rest of your makeup in place. (Which comes in handy around the 3:00-4:00 makeup horror hour. You know what I'm talking about.)
In my opinion, Smashbox wins for the best products in the business. I mean, I would bathe in the stuff if I could. Stila also has a great color-correcting product that would work well if you're looking to lighten up some spots but don't have a lot of scarring. Admittedly, both brands can be a bit pricey (though are pretty reasonable given their effectiveness), so I've included my two favorite drugstore options. Use this if you need more coverage (like me) and this if you want to add a subtle glow.
