How does BoNT-A (Botulinum Toxin Type A) Cosmetic work?
The drug is a toxin produced by the Clostridium Botulinum bacteria, and it works by decreasing the nerve signals that are sent to muscles. When the muscle wants to contract, a nerve sends a message to that muscle telling it to move and contract. When this happens, a chemical called acetylcholine is released, and it binds to the muscle side of the junction causing the muscle to move. When BoNT-A are injected, it blocks the acetylcholine from binding to the muscle side of the junction, thereby causing the muscle to be unable to contract or move.
What areas will BoNT-A (Botulinum Toxin Type A) Cosmetic correct?
BoNT-A help correct dynamic lines- lines that are caused by the many expressions we make on a daily basis. For example, concentrating, frowning, and squinting all cause hyper functioning of muscles and create dynamic frown lines. Some of them more common areas of treatment are the vertical lines in between the brow, horizontal forehead lines, and crow’s feet. However, other areas where BoNT-A can be effective in the chin, in the muscle responsible for causing the mouth to turn downward, horizontal lines and neck bands, as well as axillary hyperhidrosis (excessive sweating).
What can I expect after treatment?
Immediately following treatment, the skin where the injections occurred may appear red with a whelp-like appearance. However, this will resolve within 30 minutes to an hour after treatment and the skin will look as it did prior to treatment. Unlike dermal filler where the results are immediate, BoNT-A take about 3-5 days before results begin to be noticed. Each day, results will get better and better, with full effect taking place at 14 days.
BoNT-A are temporary and last 3 to 4 months in most people. Bruising and swelling are rare.
