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!
