Once Botox Wears Off, is It Possible for the Muscle to Have Been Trained for at Least a Slight Permanent Fix?

Botox lasts for 3 to 4 months.  After than any lasting effect are from muscle retraining.  However, these wear off as well.  The precise time frame varies from person to person.  

It is possible that after several botox treatments, your muscle habits may change and the pulling up of one eyebrow may relax. Possibly your muscles may retrain themselves after only one treatment but this is not the norm. You could try one session, and try hard not to voluntarily pull up the eyebrow as the botox wears off in three to four months, not even once, and maybe this will help long term. If you find that the eyebrow goes back up the same as it was before Botox, you don't have to continue the treatments.

I think Botox is the best option for you at this time. I understand that you don't want to get injections every 6 months, but you have to look at the alternatives.  Surgery might offer a more permanent result, but is more expensive and you might still have asymmetry.  Certainly doing nothing is also an option - so you have to weigh the expense, inconvenience and pain of injections with value of the cosmetic improvement. 

Muscle weakening takes several treatments over continuous use of Botox. It will not just happen after one use.

I wish I had a great answer or perfect solution for you.  It's difficult to say for sure what the effects of the Botox would be for your brow either short or long term without seeing you either in person or some more detailed photographs, including ones with you in different stages of animation. If the reason one brow is higher is because you have a natural tendency to raise one side then it is possible that a few treatments of Botox may help you re-learn or un-learn this behavior. If it is something that bothers you terribly and you want a permanent solution you may wish to consult a Board Certified Plastic Surgeon about your surgical options for correction.

Best of luck~

  Yes, but not with a single application or Botox treatment.  The way I look at this issue is that repeated Botox, Dysport or Xeomin injections at 3-4 month intervals, keep weakening the targeted muscle.  Eventually that muscle stays smaller or weaker.  How many treatments that takes will depend on the size and strength of the targeted muscle.
