Neuromodulator injections are perhaps the most popular cosmetic treatments worldwide today. There are two commonly used types of neuromodulators in the U.S.: BOTOX® Cosmetic and Dysport®. All three work via the same mechanism with very similar clinical effects even though subtle differences exist between the three compounds. Even though the FDA-approval varies slightly between the three different compounds, they are often used for the same purpose. Please discuss with your facial plastic surgeon what the differences between the compounds are and which substance may be best suited for you.
Both injectables treat wrinkles by temporarily weakening certain muscles that are injected. BOTOX® Cosmetic and Dysport® all contain the naturally-derived botulinum “toxin” type A that selectively blocks nerve signals and hence weakens muscles. The injections may also be performed in underarms, palms, or soles for excessive sweating. Other common uses are for chronic migraine headaches, amongst other applications.
