I have been having regular dysport injections to my face for approximately 8 years and have never had an issue with resistance. 4 months ago I had COVID for the first time and since COVID, I have tried both Dysport and Botox with absolutely 0 effect. I had the correct units (same injector for 8years) correct placement and tried again with Botox 2 weeks ago with absolutely no effect again. Is there any point in trying Xeomin and what is the success rate? Am I immune? I’m 45 and very fit/healthy.
