Got Botox injection in my masseter for jaw reduction, should I be feeling sore in my jaws?

Pain is not indicative of the Botox treatment taking effect, as it will take 10-14 days to see optimal results. If you are unhappy, I suggest consulting an expert for further treatment. Best, Dr. Emer

Thank you for your question avemarias. Botox is a purified protein used to address wrinkles associated with facial expression. Botox can be placed in the masseter muscle in the lower face to address the shape of the lower face. Some people may experience soreness after a treatment and others may not. The peak effects are seen at two weeks after a treatment, although to atrophy the masseter multiple rounds of treatment may be required. Please follow up with your doctor for specific recommendations. Good luck!

Lucky you! No pain is great. Not all patients get jaw pain after Botox injection into the masseter muscle. Sometimes soreness can occur if the jawbone is hit with the needle during the injection. I've had many patients not experience pain who were happy with the results! In your instance no pain doesn't necessarily equal no gain! Just for clarification sake, 25-35 units should be used in each side. It may take up to 10 days to have a full effect and you may need a touch up every 4 months for the first year, with increased spacing between injections as time goes on!

Hello, and thanks for your question. Consider yourself lucky! I had the same procedure done, and I was definitely sore for about a week. The fact that you are not sore does not mean the Botox will not work.  Best of luck, Dr. Frucht.   

The lack of of soreness is a positive and does not reflect the effectiveness of the treatment. I usually start new patients with a 20-25 unit injection into each masseter and most of them report a similar experience to you. You will see the muscle relaxation after 2 weeks but will have to wait 6 weeks or so for the muscle to actually reduce in size/bulk. Botox to the masseters helps with symptomatic relief but also will reshape your face, turning a squared faced into a more appealing oval face. This cosmetic effect is the result of the reduction in muscle bulk.
