How they work..
Dysport or BONTA works by temporarily immobilizing muscles, which reduce the appearance of lines and furrows.
Dysport has fewer proteins surrounding the toxin and so should stimulate a weaker immune response to break down the toxin.
Developed in the United Kingdom in the early ’90s, Dysport has been used in UK for many years. Dysport was approved by the Federal Drug Administration in April 2009 for the treatment of head-and-neck muscle spasms and deep lines between the eyebrows.
What to expect…
If you are a suitable patient for toxin injections, you will find that these are usually painless and invisible. They start to work after the first few days, reaching maximum effect by 2 weeks. For most people the effect lasts for 3 to 4 months, as it wears off you will start to be able to frown more deeply again. After a course of 3 injections over the first two years, most patients feel the effect can last 6 months or longer, thus requiring less frequent injections or smaller doses.
As with any drug, there are some possible side effects to toxin, however, because toxin only stays in the body for a maximum of six months, any side effects associated with the injection will diminish after that time period.
