Botox, Dysport, and Jeuveau are injectable treatments derived from botulinum toxin type A, which prevents muscles from contracting for several months. This reduces the appearance of wrinkles and fine lines caused by repetitive facial expressions. The treatments are injected directly into the muscles of the face using a very fine needle, and the procedure only takes about 10-20 minutes. While the results are not permanent, the wrinkle-smoothing effects typically last 3-6 months before a touch-up procedure is needed. Botox, Dysport, and Jeuveau are the most popular cosmetic treatments today.
