A neuromodulator (Botulinum toxin type A) is an injectable drug that causes controlled muscle relaxation. When we inject neuromodulators into your facial muscles, it blocks the nerve signals and prevents the muscles from tightening forcefully, allowing the muscles to relax. This muscle relaxation allows the creases in your face that are caused by muscles (think smiling and frowning) to soften. Offering visible results within days, your wrinkles and lines will continue to soften for approximately 30 days, with results lasting up to four months. In order to maintain the effects of neuromodulators, regular treatments are required.
