FAQ botulinum toxin injections

Botulinum toxin and hyaluronic acid are two complementary treatments. One does not replace the other. Hyaluronic acid is the treatment of the symptom, that is to say of the wrinkle, filling it. Botulinum toxin is the treatment of the cause of this symptom, i.e. the treatment of the muscles that cause this wrinkle to appear. The two are sometimes complementary.

The botulinum toxin injection takes only a few minutes. The injection points and the quantities to be injected are very precise and require an excellent knowledge of the anatomy of the face. These are determined in advance during your initial information / quote visit to the Centre Laser Sorbonne.

After an injection of botulinum toxin, do not massage the treated area. The muscles in the injected area should not be contracted for the first hour after the injection and you should not lie down or tilt your head down.

The effect of the botulinum toxin injection is not immediate. A touch-up may be necessary after ten days. It usually takes between 2 and 4 weeks for the botulinum toxin to fully take effect.

On average, the action of the botulinum toxin injection lasts 6 to 12 months. As the injections progress, the muscles of the face will relax, the patient will lose the habit of the facial expressions that caused wrinkles to appear, and the injections can therefore be spaced out.

The injection of botulinum toxin is a common and safe practice of cosmetic medicine, especially when carried out by a qualified doctor. As with any medical procedure, there can be rare complications. These are laid out in the information sheet of the French Society of Aesthetic and Plastic Surgery and will be explained to you during your first information meeting at the Centre Laser Sorbonne.

There is no recommended age to begin botulinum toxin injections. As soon as the first small expression lines appear, an injection of a small amount of botulinum toxin can have a preventive effect, stopping the wrinkle from widening. The aging of the face will be slowed down.
