Is it normal to only swell on one eye after PRP + Filler? (photo)

Yes swelling can be asymmetrical. Swelling usually reduces within 2 weeks. Filler to the tear trough region can cause 'festooning'. If this happens you may need to dissolve the filler.

Swelling with PRP/Filler is normal, likely because your injector had injected a little extra to promote more PRP dispersal in the area. Some fillers (dependent on the brand) can cause more swelling than others. You should allow the volume to reduce on its own for one week, before trying to manipulate it. You wouldn't want the filler to migrate where it's not supposed to be. And the PRP most likely dissipated in the first 48-72 hours after injection. If the volume does not reside and remains prominent, I would suggest following up with your injector around 2 weeks post-injection for proper examination.Best, Dr. Anil Shah 

Hi, Yes it is possible to have uneven swelling after PRP and fillers specially at the tear trough area under eyes. Also one side may get bruised and look different from the other side for 1-2 weeks. This should be temporary. If it persists after 14 days then it will require recheck.
be well
