Can anything be done to alleviate a heavy brow after receiving Botox in the forehead and glabellar area?

Depends what you mean by "heavy brow." It is very common to have a feeling of "heaviness" or even a "tightness" similar to a sun burn on the forehead/brow after Botox. This will improve on its own over a few weeks. On the other hand, if your eyebrows seem lower than they did prior to the botox this could speak to the fact that your forehead muscle (frontalis) was helping to keep your low eyebrows up until the Botox prevented them from continuing to do so.  In this case, I would recommend going back to the provider who performed your Botox to see if you would benefit from some Botox to your upper outter eyelid (right under the brow) to affect the obicularis occuli muscle.  This may help partially elevate your eyebrow. It is worth an evaluation by your health care provider who administered the Botox. 
Not everyone is a good candidate for this treatment so please see a Board Certified or Board Eligible Plastic Surgeon to evaluate if you may benefit. Good luck!

In some cases, additional Botox in the glabella and corrugator muscles will allow for a bit more lift. These 2 muscles are stronger than the thin frontalis muscle and if they are weakened sufficiently the frontalis may help lift the brows. For this reason (brow depression), I prefer to place less Botox in the frontalis muscle. Good luck

Hello,As the other panel members suggested, having certain muscle areas treated to counteract the heaviness from an over-treated forehead muscle may be an option.  This can be done by treating areas to the eye muscles that are responsible for pulling the outside tails of the eyebrows and eyelids downward.  In addition, if your injector did not treat the smaller muscles used when frowning (alongside the bridge of the nose), these can be treated to also allow for more of a lifting effect.  An over-rested forehead may happen even with the best injectors.  Making sure your current or future practitioner know what happened will be helpful in their treatment plan of using less units of Botox and/or treating higher in the forehead to avoid this heaviness.
