Since BOTOX and Dysport injections use the same substance (Botolium toxin type A), they are more or less the same product. Perhaps the only difference lies in the potency of trace proteins included in each product, which may make one product more effective than the other. Outside of that, both have been used to treat muscle spasms for years. BOTOX has also been around for over 20 years, while Dysport was also approved by the FDA in 2019. During your in-person consultation, Dr. LaBarbera will discuss preferred injection type so you get the most benefits.
