I have noticed over the last year or so that neurotoxins such as Botox and Dysport have not been effective or do not last as long in patients that I have been treating for many years in my practice. I retreated my patients with a different neurotoxin after a 3-month neurotoxin break. I wondered if other health practitioners experienced either neurotoxin ineffectiveness or a short duration of results. There have been small studies that have shown a decrease in the effect of botulinum Type A when injected close to receiving the COVID-19 vaccine. This issue was seen after an initial treatment with Dysport and with subsequent treatment with Botox Cosmetic.
