I had voluma injected yesterday and I slept on my side last night. It seems like it migrated inward on that side. What do I do?

The good news based on what you have told us is I doubt seriously that the Voluma migrated.I believe on the side you slept on, you kept the swelling down and the other side has failed to decrease the swelling yet.  Given time and the skill of your injector, I believe the two sides will look very similar if not the same.If you were my patient, I would tell you to sleep on the other cheek to decrease the swelling on the contra lateral side.  So as you see, turning the other cheek, at least for facial fillers, has some definite advantages.

Thank you for your question. Voluma is a cross-linked hyaluronic acid making it more viscous and able to last longer. Voluma is intended to allow patients to resume normal activity right away. I suggest that you discuss your recovery with your injector to ensure that you are following the recovery guidelines as closely as possible.
Best wishes,

Thank you for sharing your question.  I would recommend seeing your injector for an in-person examination. Being a thicker gel filler Voluma is typically placed deeply into the skin with less chance of migrating.  You likely have some asymmetry due to treatment swelling which should improve given time.  Hope this helps.
