What is Botox®? How Do Botox® and Dysport® Work?

Over time, our facial muscles don’t really change, but our skin becomes thinner. As it thins, it more easily creases with muscle movement. Both Dysport® and Botox® prevent wrinkles because they lessen this movement. When injected, these “botulinum toxins” prevent nerves from talking to the muscles. The molecules block this communication so that the muscle doesn’t contract. When the muscle stops contracting, the skin stops bending.

Skin rejuvenates itself constantly. It’s always remolding, turning over, building up, and tearing down. When the muscle no longer moves, the skin actually eliminates wrinkles on its own. When a crease no longer has a function, the skin removes the line as it regenerates.

The results of Botox® and Dysport® can be very long lasting. Even as you regain movement in the muscles, it takes time for the process to repeat itself and for the lines to reappear. In fact, with each injection the muscle weakens. Why? When the muscles stay still for long periods of time, they thin out and weaken from lack of use.

Think about what happens when an arm has to be in a cast. The muscles don’t move for the entire time. When the cast comes off, arm lacks strength and can’t move as well. These injections work the same way. The more injections you have, the longer it takes for lines to reappear.
