Why isn't Botox/Dysport not working for me? I'm new to these injections. Do bigger foreheads need more work? (photo)

It is difficult to give you an accurate answer without close examination but based on your description it sounds that you did not get enough botox to be effective enough.

Examining you in person would be helpful to give you the best advice.  It is possible that the Botox and Dysport have relaxed your muscle but that you still have some indentation remaining.  If this is the case, it is possible that an injectable filler could be used to obtain a smoother result in the glabellar area.  

Everyone has unique expressions. We move our facial muscles in a repetitive way and over time those repetitive movements cause wrinkles and fine lines. When you start to experience the signs of aging, Botox are available to diminish unwanted wrinkles and creases in your face.
Botox locks the release of a chemical called acetylcholine, which triggers the muscle contractions that create wrinkles. Botox essentially paralyze the muscles and stops them from contracting. Results from these treatments are visible within 3-14 days with results that can last anywhere from 3-4 months.Botox be used to improve:Worry lines in your forehead Lines between the eyebrows Smile lines Laugh lines from nose to mouth Crow’s feetNext step for you is to schedule an appointment with a Board Certified Dermatologist to discuss your options. Hope this helps.
