Lumpy Cheeks, What Can I Do?

This is a difficult question to answer without photographs.   However, given your age and overall description I would guess that you might benefit from micro-liposuction and/or some well placed volume in the face.  Although it might seem antithetical, adding more volume in the right place (upper cheek) can help support the lower volume which improves the apparent heaviness.  There may be other options as well, but a personal consultation with an appropriately boarded physician will be necessary.  At that time you will be able to have your questions answered and get some firm recommendations.
