BOTOX® Cosmetic (onabotulinumtoxinA), a prescription medicine, is a purified protein that temporarily improves the look of moderate-to-severe frown lines between the brows in adults younger than 65 years of age. It is administered by a healthcare professional as a simple, nonsurgical treatment that is injected directly into the muscles between the brows and works by blocking nerve impulses to the injected muscles. This reduces muscle activity that causes persistent lines to form between the brows. BOTOX® Cosmetic, introduced in 2002, is the first botulinum toxin to be approved by the FDA for stubborn frown lines between the brows. Approximately 11.8 million BOTOX® Cosmetic procedures have been administered in the United States since 2002. 92% of 303 patients surveyed were satisfied with the results of their BOTOX®Cosmetic experience. We were also one of the first practices to utilize BOTOX® Cosmetic for the reduction of the masseter muscles that can cause the jaw to look too square or bulky.
