Xeomin and Botox are both effective cosmetic treatments. When compared to plastic surgery and other invasive procedures, they are both relatively convenient treatments to administer. Both products start working immediately upon injection, however their full effects are only seen after seven to 14 days or longer after injection. According to one randomized, double-blind study (that is, neither the participants nor the experimenters know who is receiving which treatment), Xeomin was found to work faster and last longer than Botox. Both treatments work very similarly, although the results of Xeomin were seen for slightly longer, typically around one week to one month.
