The Botox®/Dysport® chemical, known as Botulinum toxin, is injected into your facial muscles with a very fine needle. The injections work by blocking certain chemical signals responsible for muscle contractions in the face. The injection will temporarily relax facial muscles that are used repeatedly.
The number of injections will depend on the area being treated and your aesthetic goals. It may take three to seven days to take full effect, and patients find the creases in their skin will smooth out and relax. Botox®/Dysport® can last three to four months, and as the muscle’s action begins to return, you can be treated again.
