BOTOX® has been used safely and successfully in ophthalmology since 1989. It has been used for wrinkle therapy even before its 2002 FDA cosmetic approval. Only minute amounts of diluted toxin are injected for wrinkle reduction.
A few drops of BOTOX® are injected with a tiny needle into the muscle that creates a wrinkle. When BOTOX® is injected into a muscle, it blocks the nerve impulse from reaching that area, and as a result, the muscle weakens. As the muscle weakens, the skin overlying the muscle relaxes and the wrinkles in the skin gradually soften and often disappear. BOTOX® treatment does not effect normal facial expressions.
Botulinum Toxin Type A (BOTOX® Cosmetic) is a protein complex produced by the bacterium Clostridium botulinum, which contains the same toxin that causes food poisoning. When used in a medical setting as an injectable form of sterile, purified botulinum toxin, small doses block the release of a chemical called acetylcholine by nerve cells that signal muscle contraction. By selectively interfering with the underlying muscles’ ability to contract, existing frown lines are smoothed out and, in most cases, are nearly invisible in a week.
Basically, the botulinum toxins block the signals that would normally tell your muscles to contract. If a specific muscle can’t move, it can’t cause a wrinkle.
Dynamic muscle contraction is responsible for a number of undesirable lines and wrinkles on the face. For over a decade Botox has been the only product used to reduce dynamically caused wrinkling and lines. Now with Dysport both patients and doctors have a choice. (We love competition because it helps us get better pricing for our patients!)
Dysport is very similar to Botox with the primary neuroprotein, botulinum type A, being the same. The differences lie in the dosing unit calculation due to dilution type, the time it takes to see effectiveness, dispersion of the product and possibly longevity.
Dysport for many patients seems to take effect a little quicker than Botox, and for some reports lasts a little longer.
Dysport is distributed by Galderma (previously Medicis), the same company which now supplies Restylane and Perlane / Restylane Lyft. It was developed by Ipsen, a global pharmaceutical developer headquartered in France and has been used medically since 1991.
