Are upper blepharoplasty procedures usually permanent or will you need to do a revision later on?

Hello my dear,
It’d be awesome if we could just learn how to stop the aging process!!  Unfortunately, our procedures, even surgical ones, tend not to be permanent— and only ‘turn the clock back’ to a more youthful state, and your face continues to age from there.  As other posters have commented, you’ll always look better than had you not done anything, but a secondary procedure after a period of time is often required to maintain the results.
I usually tell patients that, during an upper blepharoplasty, I’ll remove as much skin (and sometimes fat and muscle) as I safely can but still allow for complete eye closure.  This is carefully measured preoperatively.
We tell patients that, on average, the results will last about 5 to 7 years, depending on health, age, and other factors like sun exposure, smoking, and weight fluctuations.
Hope that helps,
Dr. Jay

Unfortunately people keep aging so nothing is permanent.  But the results should be long lasting and will still look better than if nothing was ever done.  Compare yourself to your photos before surgery if you still have them.  You probably still look better than your pre op photos....sometimes its easy to forget how you looked before surgery.  If you are looking to keep the improvement which was attained right after surgery, its best to see your surgeon to see if another procedure is worthwhile.
