Thank you for your question.
It is fairly uncommon to be immune to Botox. it is possible that you are receiving too small of a dose for the strengthen of your muscles.
I'd recommend booking an appointment with a highly skilled and qualified injector to ensure that you're receiving the best treatment possible.
Unhappy after Botox injections
It is not clear why you are not achieving the outcomes you would like for Botox injections. It may be that you simply require a higher dose. 4 etched lines fillers and Botox today. Be required. I would suggest consultation with a highly experienced physician who can help sort some of these issues out.
You probably just need more. 20 units is a fairly low dose. If you like your surgeon, speak to him or her about upping the ante. Best, Dr. Nazarian
You might need a bigger dose of Botox
20 units of Botox into the "11s" is typical low dose that works on most women, but you should try higher doses if you find no effect with lower doses. The forehead sometimes requires multiple rows of shots to generate smoothness if there are many lines.
20 Units is a very small dose. You probably need more. I have one patient with very thick, hyperactive frontalis muscles and deep "11"s that likes a full 50 units in that area! She doesn't get much result from less.
It is very rare for someone not to respond to Botox. Perhaps you have been going to spas and they are not injecting enough Botox. I would suggest you consult a board certified dermatologist with expertise with Botox. Best, Dr. Green
I could not tell unless I tried the botox I use on you. If you didn't respond, then perhaps you have a resistance to it. Best of luck.
It is very rare for someone to be immune or non-responsive to Botox. The problem with Botox is that it is expensive. If you are going to spas or offices where it is inexpensive, you are probably not getting much Botox and are being underdosed. To sort this out you should go to an expert injector and try one more time. If you do not respond, then I would recommend trying Xeomin.
You may need more than 20 units to your 11 lines depending on the degree of muscle activity and severity of your wrinkles. Also, if you have lines at rest then the Botox will not be able to completely get rid of them. Some people do have resistance to Botox. If you do not respond at all to increased doses then you may want to try Dysport or Xeomin. Best wishes.
Either you are not getting enough Botox or it does not have the intended effect on you. Also, it will not take care of static wrinkles that are there when your face is at rest. Fillers or laser resurfacing is needed for those.
