Tear trough filler making eyes uneven or Botox? (Photo)

It's difficult to tell from your picture, but this could be due to Botox treatment. Botox results will last 3-4 months. In the meantime, venus legacy or thermage treatments can soften results. Best, Dr. Emer

Your left eye is definitely smaller than your right. This could be from the Botox. Unfortunately, it isn't something that can be reversed like filler. However, it will fade over the next couple of months. I am sorry that you are experiencing this. You may want to try a different injector next time. Best of luck.

It looks like you have slight eyelid ptosis of the left eye - a rare side effect of botox.  This can occur when botox treatment for frown lines migrates to the upper lid region.  This typically will self-resolve as the botox wears off.  However, if you don't want to wait you can discuss with your provider using products like lopidine eyedrops which helps activate the Mueller muscles to help raise the upper eyelid.
