Procedures to remove facial fat?

I am 22 years old. 2 years ago, I took the depo birth control shot which caused me to gain 20 lbs and look very puffy and bloated, espcially in my face. Since stopping the depo, I managed to lose most of the weight but I have had minimal loss on the puffiness in my face.

My cheeks and chin are disproportionate to the rest of my body. If one were to only see my face in a picture, one would think I'm overweight, but I'm not. I was considering Lipodissolve but I am worried about the depressions, lumps and other possible side effects appearing somewhere as visible as the face.

Exercise and diet is only helping my body. What would be the best option for someone of my age to lose the fat in my face?
