Has anyone tried using body tone-up cream on sun-tanned skin in the summer?

My skin tends to tan easily to begin with, but whenever summer comes, I get really self-conscious about the patchy tan on my arms and legs. Usually, skin tanned like this in the summer doesn't whiten out until the following year after winter, but it seems to repeat itself as soon as summer comes around again. I can't go around covering my arms and legs all the time in this heat, and applying sunscreen to them feels sticky, so I feel like it would be even more bothersome in the summer. I did look around and found that body tone-up creams do exist. How do you manage patchy tanning on your arms and legs in this situation? I've heard there are body tone-up creams that provide instant tone-up with just one application... but since I've never used one before, I'm not sure what kind of effect they have.
