Botox® injections are used for cosmetic purposes to reduce certain wrinkles.
Botox® is botulinum toxin, a neurotoxin that blocks the release of a chemical that allows the muscle to contract. Thus, this product aims to reduce expression lines (wrinkles of the lion, crow's feet, forehead) by a relaxation of muscle tension. This explains why botulinum toxin is used today in cosmetic surgery.
To reduce wrinkles
In the seventies, Botox® began to be used in ophthalmology to treat certain strabismus and uncontrolled blinking of the eye.
Then gradually, Botulinum toxin injections were performed for aesthetic purposes especially by plastic surgeons locally to reduce facial wrinkles. Other products contain botulinum toxin: Vistabel®, Dysport® and NeuroBloc® (from different pharmaceutical companies).
In fact, only Vistabel® and Azzalure® have the Marketing Authorization for an aesthetic indication for the treatment of wrinkles located between the eyebrows.
How is the intervention done?
To best prepare for botulinum toxin injections, you should avoid taking aspirin 15 days before and 15 days after surgery to avoid the risk of bleeding. If you take antibiotics or anticoagulants, you have to tell the surgeon. There are also contraindications to these injections, among which:
• Certain neuromuscular diseases,
• Pregnant or breastfeeding women,
• Known cases of hypersensitivity to botulinum neurotoxin A.
The procedure is performed in a few minutes without the need for anesthesia. Injections are made with a fine needle. You feel the sting, but without real pain.
