Although I do not have the benefit of a physical examination, so I can understand where your brow sits in relation to the bony orbit of your eye, it appears that your brow has a good position, and also an excellent shape. Therefore the simplest solution for you to rejuvenate your periocular area, would be to have a skin only upper blepharoplasty, performed under local anesthesia only. This would involve only removal of some skin of your upper eyelid, preserving all of the volume to maintain your rejuvenated look. At some point in the future, if your brow does descend, a brow lift could be performed, which can also be performed under local anesthesia only. Have a detailed consultation with your plastic surgeon about these options.
