Let the experts at our Los Angeles, CA location take care of facial lines and wrinkles.
What is Dysport®?
When it comes to addressing the wrinkles caused by overactive facial muscles — forehead lines, crow’s feet, and lines between the eyebrows — Botox is known the world over. But when the FDA approved Dysport for the same uses in 2009, Botox had a new rival.
How does Dysport® work?
Repeated facial expressions such as smiling, frowning, and squinting cause the underlying facial muscles to contract. These contractions form wrinkles on the skin surface that become deeper with time. Dysport is made from the botulinum toxin type A (same as Botox) that, when injected into a muscle, temporarily paralyzes that muscle. Dysport paralyzes the muscle by blocking the nerves that signal the muscle to contract. Since the muscles don’t receive the message, they don’t contract and the wrinkles formed on the surface are reduced or eliminated, depending on their depth and the elasticity of your skin.
Dysport versus Botox
These two neurotoxins work in identical fashion, but there are subtle differences. Dysport is somewhat thinner than Botox, so it can spread to cover a wider area more easily. While this can be an advantage on areas such as the forehead, it also demands expertise from the injector to avoid migration. Dysport also has a slightly quicker onset, with its effects fully taking hold in two to five days instead of the four to seven days needed for Botox.
What should I expect from a Dysport® treatment?
Dysport is injected into the underlying facial muscles with a very fine needle. Anesthesia is usually not needed, but a topical numbing cream can be requested. Usually three to five injections are needed for each treatment area. The entire process only takes around 20 minutes.
How long will the results from my Dysport® treatment last?
Dysport’s muscle-paralyzing effects last from four to six months before the body metabolizes the product. At that point, the muscles will begin to contract again, forming wrinkles. A follow-up session will then be required to maintain your results. There is evidence that as the muscles are injected with Dysport over time, they become conditioned to relax and tend not to contract as forcefully in the future.
Are there any side effects with a Dysport® treatment?
The side effects of Dysport are slight bruising at the injection sites, possible headaches for the first day or two, and very infrequent eyelid drooping (this is caused by Dysport migrating to a non-targeted muscle). Overall, the safety record of Dysport, like Botox, is impeccable.
