What is the recovery like for a brow lift and what else should be combined with it to make my eyes more symmetrical?

Even if you have slight brow ptosis you will like the Browlift more IF when you gently elevate your brows with your fingers you like that look! Otherwise an upper blepharoplasty.

You are a wonderful candidate for browlift plus upper blepharoplasty.   A browlift can improve the asymmetry significantly but you still will have some excess eyelid skin.   In my hands the recovery for complete  resolution of bruising and most of swelling is 10 days.   People can reliably return to work at that time.  I have found that a temporal browlift gives equivalent results to endoscopic browlifts and can be done under light sedation and local anesthesia.

Your photos show asymmetric brow ptosis and redundant skin of the upper eyelids.  An endoscopic brow lift can improve your brow symmetry using a few small incisions hidden behind the hairline. Through these small incisions the brow can be released and lifted to the desired height, shape and contour. An upper lid blepharoplasty can be added to this procedure to reduce the fullness of the upper eyelid and further open your eyes. Downtime with these procedures is one to two weeks. A consultation with a surgeon experienced in both endoscopic brow lifts and upper eyelid blepharoplasty would be a good next step to learn more about these procedures.

Although you do not appear to have ptosis (droop) of the eyelids from the pictures presented, the first thing I think of with asymmetrical eyebrows is asymmetrical ptosis with one eyebrow trying to keep the worse eyelid elevated the same as the opposite side. You need an evaluation by a plastic or ophthalmic plastic surgeon experienced in evaluating and treating ptosis.

Your best chance for symmetry of your eyebrows is an endoscopic brow lift with special attention to the asymmetry present. The procedure is performed under local anesthesia with some IV sedation. The recuperation is about a week or less, depending on the swelling or the technique employed.
