Hard Pronounced Cheeks After Juvederm Voluma?

With any injection there will be some swelling and possible bruising creating hardness where you were injected.  Re evaluate your injections in a week and if you still see some unevenness then call your physician. 

 Voluma should add volume to the cheeks to give it that contoured look and improve the 'hollow' appearance. If you aren't satisfied, after a second appointment see a more experienced doctor to get the best results or consider reversing with hyaluronidase. it takes 2 weeks to see the swelling go down. Radiesse and sculptra are good alternatives.

At the moment you are affected by swelling which should resolve over a few days. Lumps and bumps usually resolve on their own, once the filler starts to get incorporated with your own skin tissue. It would be best if you book a follow up appointment with your injector in 1-2 weeks, and he/she can massage any residual lumps or bumps at that time.

Your cheeks do look a little full, but I see other areas that if addressed would blend and create a more harmonious correction. So rather than having it removed I would encourage you to give it another week or so and consider adding another softer product to this.

 It is fairly common to have some hardnes and bumps up to two weeks after Juvederm.  It will likely settle in and be fine.  Try not to panic, because it takes a few days for the Juvederm to settle in and swelling to resolve. I like to look at my filler patients in 2 weeks, as this will likely be close to the final result.  If more filler is needed to even things out, it can be discussed at this time. I would continue to place ice on the area , as this can help with the swelling.
