Can under-eye filler make my eyes symmetrical again? (photos)

this can only be fixed surgically however botox under the eye on the side that is less "open" may help.  filler will only Improve the hollows but will not help the shaping of your eyes.  sometimes I use threads and Its successful. its really hard for most people to appreciate what you see.  Best, Dr. Emer.

Under-eye filler can certainly help the hollowness you are seeing. It will not change the shape of the eye or alter how large it looks, but it will fill any emptiness under the eye. I recommend you consult with your dermatologist to see if this is the right option for you.

Yes! A common effect after blepharoplasty surgery is hollowness under the eyes. Even with the fat being repositioned, there can be sunken areas which require filler treatment to get a smooth contour. This is accomplished well with Restylane Refyne, which is my favorite choice to use under the eyes. Refyne is smooth, swells minimally, looks natural, and blends seamlessly. It may require 2-3 sessions to obtain complete correction, so be patient with the process and choose and experienced provider. Good luck!
