Dysport vs Botox: What’s the Difference?

Dysport may be the new kid on the block in the U.S.A. (on the market since only April, 2009), but it has been battling Botox in Europe for years. Both Botox and Dysport are botulinum toxin type A proteins and work in a similar fashion. Dysport may be minimally less expensive, but not enough to make any significant difference.  So how do you choose between Botox and Dysport?


Measuring Botox and Dysport is different (Botox units are larger than Dysport units), but this is a technical consideration for me and not really relevant to you. Some of my clients believe (and I agree) that Dysport may begin to work a bit faster than Botox, by as much as one to two days earlier, which may be an advantage if you need a really quick fix; otherwise, this isn’t of much practical importance. 

Duration of Effect

Botox and Dysport may last about the same time for about 3 to 6 months, although there are some of my clients (and I tend to agree) who claim that Dysport lasts a bit longer.

The beneficial effects of both Botox and Dysport can be prolonged, sometimes for quite some time longer than the ordinary four to six month duration, by suggesting that the patient undergo a series of three or four initial treatments, spaced at four month intervals. It seems that the continual presence of the Botox or Dysport in the muscle tissue during that period “teaches” so to speak the muscles of facial expression not to contract as actively as they did before treatment. It is this learned “lesson” that is believed responsible for the more prolonged response seen in many people, even after all the toxin has been metabolized away by the body.

At least theoretically, some people who have become “resistant” to Botox, usually after repeated treatments, may respond to Dysport. Dysport may diffuse (spread) over a wider from the injection sites than Botox. The advantage here may be that you can treat broader areas, such as the forehead and underarms with fewer needle sticks.

The flip side is that tighter narrower areas, for example, under the eyes or under the eyebrows, must be carefully treated to insure limiting spread beyond the desired treatment areas. In conclusion, the jury is still not in on any significant differences between the two products other than they are produced by different manufacturers. For now, the choice of which agent you will be treated with may depend upon the doctor’s comfort level and experience with each product and the particular needs of the patient.
