What are they?
Denevervating agents (onabotulinumtoxina), available as Botox and Dysport, work by temporarly blocking the nerve receptors on the muscle to inhibit wrinkle formation, specifically between-brow lines that resemble the number 11. By decreasing forehead furrowing, they eliminate wrinkles and fine lines that currently exist and also prevent new ones from forming, making them favorites of patients of all ages.
In addition to cosmetic applications, many of which are considered off-label (see below), Botox is also FDA-approved for hyperhidrosis (excessive sweating). While the off-label uses of Dysport are still being explored, it is believed to have the same abilities, although different dosages may be required.
Denervating agents have played a major part in the age of injectables, and doctors continue to find new and novel uses for them, as well as innovative ways to use them in conjunction with fillers.

Treatment and Results
Just like injectable fillers, a topical anesthetic may be applied to make treatment more comfortable. Then, over roughly 10 minutes (depending on how many areas are being treated), your doctor will strategically place several injections.
Although the overall experience is the same as with Botox, the main difference is that Dysport kicks in quicker—the results can usually be seen in a day or two, whereas Botox takes three to five days. The results of both are believed to last about the same amount of time: on average, three to four months. However, after a series of injections, Dysport may last up to six months.
Side Effects and Risks
You may be red or bruised at the injection site for up to a few days, and in rare instances, patients have reported mild flu-like symptoms after treatment.
Not Appropriate For…
Botox is not a filler, so it should never be used in ways that a filler might.
