Xeomin® is made through a unique precision manufacturing process that isolates the therapeutic component of the molecule and removes the complexing/unnecessary proteins that don't play an active role in treatment. Xeomin® is a uniquely purified neurotoxin. Studies have not been performed to determine whether the presence or absence of complexing/unnecessary proteins has a long-term effect on safety or efficacy.
Frown lines form when facial expressions are made as the muscle under the skin contracts. Over time, as your skin ages, these repeated expressions cause lasting frown lines. Neurotoxins, such as Xeomin®, are prescription medications that block the release of chemicals that cause these muscle contractions so frown lines are softened.
