Botox® has been the most popular physician administered cosmetic procedure in the United States for the past five years. Over 4 million treatments were performed in 2006. Only licensed and trained healthcare professionals can administer Botox® Cosmetic. The muscle relaxing agent is derived from the purified protein in Clostridium  Botulinum and has been very safely used for years. A treatment involves several injections of the muscle-relaxer with a very fine needle. Maximum results are typically seen in 10-14 days. Results last 3-4 months on average. Treatments may last longer as they are repeated over the course of time.
