It may be a miracle in a bottle and the ultimate wrinkle eraser, but do you really know what’s going on when a single dose of any neuromodulator (BOTOX®, Dysport or XEOMIN®) gets injected?
Neuromodulators temporarily inhibit the nerves that signal certain muscles to contract. Once these muscles are weakened, they can’t make the movements that cause lines and wrinkles (you can still make facial expressions, but they may not be as exaggerated). After a few months, the muscles regain activity, the line-smoothing effects begin to diminish and the treatment needs to be repeated.
