How long will 6 units of Botox injected into the forehead (midlines) last?

Thank you for your question.  Botox cosmetic wears off in an approximate time frame of 3 to 4 months.  So sorry that you are disappointed with your treatment.  I wish you good luck.

I’m sorry to hear of your negative experience with BOTOX®. Because you only had 6 units injected, your results will likely dissipate by the 2 month mark. It’s important for BOTOX® injectors to have a detailed understanding of facial anatomy so that a heavy brow isn’t the result. A skilled BOTOX® injector strikes a delicate balance between smoothing forehead lines and maintaining brow position. BOTOX® injections between and around the eyes may also help to offset some of the brow heaviness you’re experiencing.

Thank you very much for your question. I’m sorry you are unhappy with the results from your Botox treatment. On average, the results from Botox injections will last from three to four months. However, this will depend on the amount of Botox injected, the treatment area, and the individual patient. Results from the toxin will gradually fade, and with your very small dose,  you will notice some changes much sooner than three months. I recommend you speaking with your Botox provider, as additional injections can potentially counteract the issues you are experiencing. 

6 units is very little but some people are very sensitive.  4-6 weeks and it should settle a little.  Best, Dr. Emer.

Six units is a small dose.  The heaviness you are feeling may wear off sooner than 3 months.  You may consider returning to your injector to see if more Botox can be placed in other areas to counteract the heaviness you are feeling.
