Key takeaways
Botox Cosmetic (onabotulinumtoxinA) and Daxxify (daxibotulinumtoxinA) are both neuromuscular blockers used to temporarily improve the appearance of frown lines. They work by relaxing muscles to reduce wrinkles. However, they have some differences. Botox Cosmetic is specifically approved for frown lines, forehead lines, and crow's feet, while Daxxify is approved for frown lines and neck spasms (cervical dystonia). Botox Cosmetic is typically injected every 3 months, with effects lasting up to 4 months, whereas Daxxify can last up to 6 months or longer. Both medications are only available as injections given by a healthcare provider, but neither is available in a generic form. Common side effects for both include headache, drooping eyelids, injection site reactions and muscle weakness. Both medications carry risks of serious side effects if the toxin spreads beyond the injection site, so it's important to follow your provider's instructions carefully.
