Am I a good candidate for a brow lift to correct asymmetry?

It is difficult to tell from these photos whether a brow lift would actually give you the change you want. It is possible that strategically placed injections of Botox may be a better choice for creating symmetry and subtle lift. However, I would schedule a consultation with a board-certified dermatologist who can assess you in person. Through this meeting and discussion of your specific concerns, your doctor can help you determine the best treatment option for you. 

To give the eyebrows a nice lift, we use injectable fillers to improve the eyebrow, upper eye, forehead and temple. A filler is placed on the bone and in the fat pads of these areas to contour and lift without it looking overdone. We use cannulas to limit pain and swelling. I suggest getting a formal consultation with a facial sculpting expert. 

 The Limited photographs demonstrate adequate position of the eyebrows, and a brow lift only make you look surprised on a permanent basis. Consider Botox for the expression lines between your eyebrows

Asymmetry of the brows can be improved with a lift but these pictures do not show a significant difference that can be surgically improved. Having said that I suggest you be examined by a specialist in this field. Pictures are sometimes misleading.
