How noticeable is my orbital asymmetry? (photos)

You probably will benefit from a detailed oculoplastic assessment.  It can be helpful to determine the basis of your orbital asymmetry.  Hyaluronic acid fillers and cosmetic botulinum toxin can be helpful.

You pose a very good question, and your photos demonstrate underlying bone asymmetry of your orbit that has resulted in relative hollowing of the left side and some brow asymmetry. In my opinion,  this degree of asymmetry at this point in your life is fairly minor, and fits in within the range that is seen in normal people.  With aging, these asymmetries can become more pronounced. From a social standpoint, it is probably  not consciously noticeable by others, although unconscious aesthetic recognition does occur on a routine basis and can lead to a perceived reduction of attractiveness. That having been said, your asymmetry is minor.  Ultimately, the yardstick that I use for patients is that if you are focused on a perceived negative anesthetic feature when you look in the mirror- more than twice a week – and wish it were different – considering treatment is reasonable. The good news is that achieving improved symmetry with a noninvasive filler treatment would be a simple solution.  You can check out the image on my photo profile of the patients who underwent filler for asymmetry to view a similar situation and outcome. Certainly anyone in your area that is experienced with her periorbital fillers should be able to achieve a similar results. Good luck to you! 

First and foremost, you should know that no one, even the most beautiful models, have perfect facial/orbital symmetry.  From your photos, it appears that what small amount of asymmetry you have is will within normal limits, and I would not suggest any surgery for this at this time.  If you wanted, a good cosmetologist, could give you suggestions on makeup, which could make this slight asymmetry become imperceptible.  But don't worry, you are very attractive without any makeup at all.  Best wishes, Dr. Lepore.
