Your left eye socket sits higher in your skull and the right side. Likewise, the brow is higher on the left side. This is based on facial skeletal structure and should probably not be addressed. If you lower the left eyelid, then it will sit closer to the lash line and you’ll develop a new asymmetry. All people have significant facial asymmetry. During embryological development, the two sides of the face develop independently from each other and eventually fuse in the midline. The human brain is used to seeing facial asymmetry as being normal. You probably don’t think of your friends and family, as having uneven eyebrows, eyeballs, or facial asymmetry in general. All of them do. it takes the significant amount of facially symmetry before people notice something being different. Likewise, asymmetry has nothing to do with aesthetic looks. Looking attractive is much more related to balance than symmetry. I recommend you leave this alone. Best, Mats Hagstrom MD
