Dry/Discolored skin?

on the corner of my lips. I used to get really dry flaky skin there, it hasn't been bad lately because I moisturize every day with face lotion, except I use coconut oil on my entire body after I shower. (I shower two or three times a week). But I've noticed it has been getting darker? Not dryer, darker. And it's making me feel like a puppet. Does anyone else have any dry dark areas on their body and can help me get rid of it? My only guess is to start wearing makeup to have an even skin color :\
