I have had 40 units of Botox in my glabella in the last 3 ish weeks and still have full movement. (Photo)

The typical dosing for treating frown lines using Botox injection into the glabella is 20 units. 40 units for the glabella is a lot and a dose usually reserved for men who have much stronger muscles. I recommend you see another injector for a  second opinion. Good luck.

Thank you for your question and for sharing your photograph lynn5115. I understand
your concern. Botox is a purified protein used to address wrinkles associated
with facial expression. It is difficult to make an assessment in the absence of an after photograph and in the absence of photographs while frowning.One of the most common areas treated with Botox is the glabella, the area between the brows. When injected into the skin in the area Botox will relax the muscle group and smoothen out the overlying wrinkles. The wrinkles seen here are typically vertical in orientation and get deeper when frowning. When we perform such treatments in our office we take photographs of our patients frowning before a treatment and two week later to assess the results, when the final results are expected.The pivotal studies demonstrated that when 20 units of Botox is used in the glabella, the peak effects are seen 14 days after a treatment and most people enjoy their results for 3-4 months. At that point a maintenance treatment is recommended. In practice I find that some patients require a higher dose. This frequently occurs in mature patients, in those with stronger muscles, and in men.In rare circumstances a batch of product is not effective. In this case the treatment can be repeated using product with a different lot number. Alternatively a different neuromodulator such as Dysport or Xeomin can be used. In other rare cases, some people are resistant to a certain neuromodulator such as Botox. In these cases other neuromodulators can be tried as well.
Please consult with a doctor for specific
recommendations. Good luck!
