Are Multiple Brow Lifts Possible?

Actually, this is not an unusual request, for as you continue to age and the effects of gravity weigh in on your forehead and brows, there can be a return to some degree of the hanging eyebrows. Many times, with these secondary procedures, I will not recommend a second endoscopic browlift, but instead a skin only lateral browlift. While a simpler procedure to recover from, and not requiring anything deeper than some mild oral sedation, that is not the reason I would recommend it, but rather for its superiority in directly elevating the skin of the brow region, which is usually the main problem area, and giving the best results.

Although most of the time, browlifts are done only once in a person's life, performing a second one is certainly possible.
Whether you will look "done" does not depend on the procedure or how many you have had but rather on the goals and careful execution of the procedure. Therefore, the answer is "you should not look operated on" but everything is possible...
Most patients I see for secondary browlifts either had no noticable improvement a year or so following their (usually endoscopic) browlift or their brow tails (ends of the brows towards the sides) require additional lifting.
You can stand in front of the mirror and lift your brows with the help of your fingers to see what kind of an improvement may look good and natural.

It is not uncommon to have a second procedure after 10 years.  Consult with 2 - 3 experienced and expert board certified plastic surgeon to determine whether you should have another endoscopic brow lift or alternative procedure.
