Botox, Xeomin, and Dysport are all neurotoxins that are used to treat wrinkles and facial lines. While they all work in a similar way by temporarily paralyzing the muscles, there are some differences between them. One key difference is their formulation. Botox is made from onabotulinumtoxinA, while Xeomin is made from incobotulinumtoxinA, and Dysport is made from abobotulinumtoxinA. Another difference is their onset of action. Botox typically takes around 3-5 days to start working, while Dysport may have a faster onset of action, sometimes within 1-2 days. Xeomin falls in between the two, with an onset of action within 2-3 days. It's important to note that the effectiveness and longevity of these treatments may vary depending on the individual and the area being treated.
