What causes frown lines?
Over time, repeated movement of the facial skin by the forehead muscles forms lines between the eyebrows. Frown lines are "dynamic"—they happen because of the way a person's face moves.
Are they related to age?
No. Because frown lines are created by facial movements, such as frowning or squinting, they may develop even in younger adults.
Prescription Dysport temporarily improves the look of your frown lines without changing the look of your whole face. Untreated facial muscles still work normally.
What is the most important information you should know about Dysport?
Spread of Toxin Effects: In some cases, the effects of Dysport and all botulinum toxin products may affect areas of the body away from the injection site. These effects can cause symptoms of a serious condition called botulism. Symptoms of botulism can happen hours to weeks after injection and may include swallowing and breathing problems, loss of strength and muscle weakness all over the body, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice, trouble saying words clearly, or loss of bladder control.
Do not have Dysport treatment if you: are allergic to Dysport or any of its ingredients, are allergic to cow's milk protein, had an allergic reaction to any other botulinum toxin product (such as Myobloc® or Botox®), or have a skin infection at the planned injection site.
The dose of Dysport is not the same as the dose of any other botulinum toxin product. The dose of Dysport cannot be compared to the dose of any other botulinum toxin product you may have used.
With just 1 injection into each of 5 points between and over the eyebrows, Dysport blocks the signal from the nerve to the muscles, ultimately resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles that cause frown lines. You should not be treated with Dysport more frequently than every 90 days.
Treatment with prescription Dysport can temporarily improve the look of your moderate to severe frown lines. Treatment generally takes just 10 to 20 minutes.
The most common side effects of Dysport treatment are nose and throat irritation, headache, injection site pain, injection site skin reaction, upper respiratory tract infection, eyelid swelling, eyelid drooping, sinus inflammation, and nausea. You should wait at least 90 days between Dysport treatments.
