Key takeaways
Xeomin (incobotulinumtoxinA) and Botox Cosmetic (onabotulinumtoxinA) are both neuromuscular blockers used to treat frown lines, but they have some differences. Both medications are injected by a healthcare professional and work by stopping a chemical called acetylcholine, which helps relax muscles. Xeomin is FDA-approved for treating various conditions, including excessive drooling, arm and neck spasms, and eye twitching, as well as frown lines, while Botox Cosmetic is specifically approved for improving the appearance of frown lines, forehead lines, and crow's feet lines. Xeomin is used for both medical and cosmetic purposes, whereas Botox Cosmetic is only for cosmetic use, though other Botox products have additional medical uses. Xeomin's effects can be seen within 7 days and last 3 to 4 months, while Botox Cosmetic starts working in 1 to 2 days and can last up to 4 months. Common side effects of Xeomin include dry mouth, diarrhea, and muscle weakness, while Botox Cosmetic may cause drooping eyelids and headaches. Both medications have risks of spreading toxin effects, which can lead to serious side effects like trouble breathing or swallowing. Neither medication is available in a generic form, and both require repeat injections as their effects are not permanent.
