Advanced Dermatology participated in the study that led to FDA approval of Xeomin as an alternative to Botox and Dysport. Although introduced in the US in 2010, Xeomin has been used successfully in other countries since 2005. Like Botox and Dysport, Xeomin is designed to treat brow wrinkles, crow’s feet, bunny lines, and frown lines. The active ingredient, botulinum toxin, is exactly the same as in Botox and Dysport. Patients whose cosmetic results with Botox or Dysport are unsatisfactory may have more success with Xeomin.
