Is there any non surgical/ non invasive things I could do to fix my uneven eyebrows? (photo)

Eyebrow asymmetry is very common.  That being said, Botox can be used to improve pre-existing asymmetries.  It's important to be evaluated by a Facial Plastic Surgeon, Plastic Surgeon, or Oculoplastic Surgeon to rule out underlying eyelid ptosis (drooping).  In that situation, an uneven brow can be a compensatory mechanism to try and elevate the drooping eyelid.  Best of luck.

First of all a certain amount of asymmetry is completely normal in all people. I have yet to meet someone who is perfectly symmetric. So that to begin with should not be the expectation. You have lots of attractive features and though you may be acutely aware of the asymmetry in eyebrows I would suspect that it goes largely unnoticed by others. Having said all of that, Botox can be used to lower or raise a brow so that would be the simplest and least invasive way to achieve improved symmetry. Of course seek out an qualified dermatologist or plastic surgeon who can rule out any nerve function issues as well. Best of luck.
