Neurotoxin, better known under brand names such as Botox Cosmetic®, Dysport®, Xeomin®, and Jeuveau®. Neurotoxin treatments are the most popular single cosmetic procedure in the U.S. and are primarily used to smooth the appearance of facial wrinkles that form as a result of repetitive facial movements like frowning, squinting, smiling, and other expressions we tend to make daily. This treatment works by blocking nerve impulses to the muscles, causing them to relax. As a result, your expressions soften and the dynamic wrinkles are reduced!
