This is difficult to answer without pictures. Botox may be used to improve symmetry of the eyebrows. Results last 3-4 months. See an expert. Best, Dr. Emer
The picture you have posted shows that you have a slight facial asymmetry (we all do). The left orbit is slightly higher than the right. Left me stress slightly. The right upper eyelid has a small ptosis. There appears to be a compensatory left eyebrow elevation. That suggests that there may be a latent ptosis of the left upper eyelid. Detailed testing in the office setting would determine if both eyelids need a small ptosis procedure or just the right side. The differences are so small I would encourage you to try the Microdroplet Lift® with botox as an alternative. Look on the Microdroplet Lift website and find an injector close to you for the service.
