Dysport (abobotulinum toxin A) is similar to Botox (onabotulinumtoxin A). Dysport reduces the appearance of fine lines and wrinkles by temporarily blocking the contraction of select facial muscles. Dysport is injected using several injections into the muscle with a very fine needle. Dysport begins to take effect more quickly than Botox due to its smaller molecular size. As Dysport starts to take effect over 2-3 days, and reaches maximal effect over the next 1-2 weeks, the overlying skin becomes smoother. Like Botox, Dysport specifically treats the wrinkles that occur during contraction (dynamic lines). Wrinkles that are present at rest (static lines) are often not initially eliminated, but can soften with time and regular injections as the underlying muscle stays relaxed. For most patients, the effects of Dysport are the same as Botox. For others, Dysport is more effective in reducing wrinkles or causes fewer side effects than Botox. During your consultation, we will discuss which product is a good initial treatment for you.
