Can filler in cheek cause bags under eyes? I massaged it and it's much better now..

Yes fillers in the upper cheeks can cause swelling that goes to the under eye. I suggest seeing your physician for an evaluation to determine what can be done at this point. Best, Dr. Emer.

Thank you for your question.  Depending on the style and location of filler placement there can be some temporary asymmetry or irregularity that can develop.  Because yours improved after massage, it sounds as if the technique of filler placement may have led to the bags under your eyes.  Happy to hear that they resolved.  

It is possible that when the cheeks were injected you got some swelling from the injections themselves.  It is also possible that they injected product under the eye.  I would give it two weeks and sleep on your back for a few nights.

If the filler was placed to high and too superficial to the underage area, it could hydrate and create the appearance of a bag. It could also be temporary swelling from the injections themselves. Give it a few days and re-asses. if it is persistent, and the filler is a hyaluronic acid, it can be dissolved.

There are many hyaluronic acid fillers that are commonly injected in the face.  Some of these products are more hydrophilic (attract water to the injected area) than others.  Voluma is the least hydrophilic of all the hyaluronic products available in the U.S..  Other products such as Juvederm Ultra, Juvederm Ultra Plus, Restylane, Restylane Lyft, and Restylane Silk cause significant edema (swelling).   When placed superficially near the lower eyelids, any of these products will produce "bags" (edema) under the eyes. It is unusual to have the swelling you describe with Voluma.  Please confirm the filler used and the exact location you received injections.  You are welcome to upload your photos for review.
