The botulinum toxin is a substance that reduces the contraction of muscles. The reduction in the tone of certain facial muscles helps reduce expression lines, rejuvenate the look and reduce sagging of the lower face and neck.
The toxin has been authorized in France since 1990 to treat certain diseases linked to muscle contracture in ophthalmology and neurology. Its use in wrinkle treatment is old, but it was legalized in 2003.
Principle of Botulinum Toxin injections
One week before the injection, it is recommended not to take drugs that modify blood flow (aspirin, anti-inflammatory drugs, etc.) in order to reduce the risk of hematomas. After the injection, it is recommended not to do intensive sports and not to massage the injected areas for 24 hours.
The results are visible after a few days. During the first fifteen days, the effects on the face can be variable (even asymmetrical at certain times) then stabilize in the 3rd week.
We are considering a possible touch-up at 4 weeks. The effects last about 5 to 6 months. With repeated injections, the results tend to linger longer.
