5 days after Juvederm Voluma 2ml 1ml was administered in each cheek. Got a circle more when I smile, is this swelling? (photo)

Yes, you have swelling, which can last 1-2 weeks after filler injections. If you're unhappy with your final results, you can have it reversed with hyaluronidase and try a different technique next time. See an expert. Best, Dr.

Thank you for sharing your question and photographs.  Based on the appearance of your current results this appears to be swelling in your cheek tissues and should resolve over the next 2-4 weeks.  It often takes up to 2 weeks for fillers to soften and the tissues to appear more natural.  In the meantime try reducing the swelling by using cold compresses to your lips and elevating your head at night with a couple of extra pillows behind your back.  You may want to also consider using Arnica Montana and bromelain as supplements.  Hang in there!

Yes, this is most likely swelling. Swelling can be typical. Icing and cold compresses may give improvement. I would wait a full 2 weeks before judging the results. If it is after the two week wait, you can have the filler reversed with hyaluronidase.
I hope this helps!
