Xeomin is a prescription medication that contains botulinum toxin type A, which is used to temporarily improve the appearance of moderate to severe frown lines between the eyebrows. It works by blocking nerve signals to the muscles, reducing their ability to contract. This results in a smoother appearance of the skin in the treated area. Unlike some other similar treatments, Xeomin is unique because it does not contain any additives, making it a purer form of botulinum toxin. This can be beneficial for individuals who may have developed resistance to other treatments. The effects typically last for several months, providing a refreshed look.
