What causes verticals lines below brow after botox treatment?

Thank you for your question.With Botox, there is a way to give our patients a non-surgical brow lift by tricking the brain.  It seems this is what you had.  Occasionally, the brow lift is too strong and when the eyebrows go high, it pulls on the upper lid skin and creates those little vertical lines.  Those are easily corrected by adding a few units to the outer forehead.Hope this helps!Kind regards,Dr. Marc DuPere, aesthetic plastic surgeon

Sometimes after a Botox treatment, nearby muscles may compensate creating other lines. Botox results last 3-4 months. If you're unhappy with your results, venus legacy treatments can soften results. See an expert. Best, Dr. Emer

Thank you for your question.  It is likely that the Botox injection has caused the affected muscle to relax and an adjacent muscle to react.  Best to follow-up with your injector for a small correction.  Good luck.

It is hard to give concrete advice without understanding how many units (total) Botox your received.  Use of 1 unit in the region of the brow is not likely to achieve anything other than a confused patient. 

Sometimes with botox use, other muscles are recruited to move. You are best to show photos to see what your concerns are.
