FDA approved for the treatment of wrinkles, botulinum toxin therapy (commonly known as Botox, Xeomin, or Jeuveau) is an injectable form of botulinum toxin therapy that improves the appearance of moderate to severe frown lines, crow’s feet, and forehead lines. Certain wrinkles, called dynamic wrinkles, are created by repeated muscle movements during common behaviors such as frowning or squinting. When injected into the muscle that creates a dynamic wrinkle, Botox, Xeomin, and Jeuveau block the nerve signals to the muscle, stopping the muscle from contracting. The effects last about three to four months, depending on what area you are treating. Some of the side effects might be pain, swelling, bruising, headache, upset stomach, or flu-like symptoms. Botox, Xeomin, and Jeuveau treatments are simple, safe, and typically take about 15 minutes.
