Minimum Waiting Time for a Second Brow Lift?

1 year - Yes - Yes ... are my answers to your questions.
Being patient before revision surgery always pays off! Although there is no strict rule, you will likely experience a little more settling of the brows over the next 6 months although much less than during the first half a year. Surgically, it is relatively easy to raise the central brow. The temporal brow tail on the other end requires convincing measures for it to stay up after a browlift. Therefore, a browlift is more of a resculpturing procedure than a simple lift.

You would be best off to wait one year before beginning the process of second brow lift. As your question suggests that you understand, there will be more relaxing of the skin and healing to occur.

Actually this is a common scenario- the lateral brows dropping after an endoscopic browlift, due to the sliding of the skin and brows over the sub-brow fat pat at as soon as several weeks after the procedure. I usually recommend the lateral subcutaneous limited browlift that can be performed under straight local anesthesia, and takes less than 1 hour to perform and heals up quickly in most cases.

It is probably best to wait at least a year for full healing to take effect prior to embarking on a secondary browlift procedure. It is important to let the skin relax, the incisions heal, and all scar tissue be permanent before embarking on a secondary procedure. It is also important to make sure that whatever forehead muscle work was done at that time has had adequate time to recalibrate before embarking on another procedure.

One of the problems with forehead lifts is positioning of the lateral brow. The lateral brow lift can help you achieve a lift in this area. The exact timing of this secondary procedure should be left up to your surgeon. He knows your case, anatomy and tendencies and is in the best position help make the correct choice as far as timing.
