I had Juvederm injected into my nasolabial folds yesterday. One side looks like swollen pillow face. What shall I do? (Photo)

It's too soon for final results. 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!

It takes time for the swelling to resolve after an injection of a filler, especially if the injection was just done yesterday. I suggest you call your injector and discuss the concern you have and get an examination of the area. You should be evaluated for a possible infection or an allergic reaction in the injection site. If your injector does not think that there are any signs or symptoms of infection or an allergic reaction, give the area at least 10 - 14 days for the swelling to go away. If it is not resolved at that time be re evaluated.
