How do you get rid of color variations on your skin?

My face is brown and my body tan %26amp; my arms up to the shirt are brown too and the other part of my arm is tan %26amp; my legs are brown too, what should I do. Do food that you eat change this problem?|||sound like you have a farmers tan. That%26#039;s where you have a darker tan line where your skin shows everday (like arms and legs). If you can tan outside, apply SPF 45 to darker tan area and spf 15 to rest of body and tan outside with out shirt (or shorts, if you want). Foods wont effect it at all.|||wtf?
