Yeah, there are different things you can do... the foundation/concealer trick is a good one, but I would def say that pumpkincat210's suggestion of lip liner is the best because it is something that will make your lipstick last longer. Also, certain formulas of lipstick will cover that right up. Amplified Cremes for example. I even got a luster to cover it up once, but that was after god knows how many coats.
