In young patients with asymmetric brows, surgical intervention is not appropriate. The majority of the time, the asymmetry is due to overuse of the brow elevator muscle; so treatment, if necessary, is limited to neuromodulators, such as Botox.
That is your personal decision. If your asymmetric eyebrows bother you, there are certainly procedures available to improve the symmetry.
I feel you are being a little hard on yourself. Everyone of us details our looks in a mirror. Your needing a Browlift at your age would be highly unlikely. If you are still concerned, getting an exam by a board certified surgeon who does lots of brow lift work can give you a concrete answer.
It is difficult to tell by the photo what correction is needed but rest assured that we all are a little asymmetrical. If it bothers you, you should seek the advice of a board certified facial plastic surgeon.
It is very difficult to diagnose your problem from the photo. I would suggest a consultation with a board certified surgeon specializing in facial plastic surgery. Good Luck!
Poorly posted photo. So can not advise but best to seek ONLY IN PERSON opinions from boarded surgeons...
