Chundury et al found that patients who preferred treatment with incotulinumtoxinA felt that it was more effective, while those who preferred treatment with onabotulinumtoxinA felt that it had a longer duration. [55]

However, Saad and Gourdeau found in a “split-face” technique study that no difference was noted in either subjective or objective measures between the two toxins. [56]
