Dysport vs. Botox: what's the difference?

Dysport may be new in the U.S. (on the market since only April, 2009), but it has been battling Botox head to head in Europe and elsewhere for several years already. Here's what we know so far about the battle of these big boys in the nonsurgical esthetic arena: 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 so to make any significant difference cost-wise to the consumer.

Dosing is different than Botox, but this is a technical consideration for the doctor to know and is not really relevant to the patient. 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 have a big party a couple days later and need a really quick fix; otherwise, this isn't of much practical importance. Botox and Dysport may last about the same time, although there are some who claim that Dysport lasts a bit longer, but not significantly much 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 "resistent" to Botox, usually after repeated treatments, may respond to Dysport. I have already had one such patient in my Manhattan practice. 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 (for hyperhidrosis, i.e. excessive sweating), 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.

Dysport is another form of Botox with few differences. Dysport becomes effective up to 24 hours after injection because it is a smaller protein, whereas Botox may take up to a week to be effective because it is structured slightly different.What is important is that both Dysport and Botox contain the main active ingredient called Botulinum Toxin Type A, which creates effectively the same results with patients. Some patients prefer Dysport because they say it gives them a more natural look.

Price is one factor. But of course it is not the most important factor. Ultimately you want this medical procedure done by an experienced expert that can do this safely and with the best results. 
Some patients may see that one will work better for them over the other, but essentially botox and dysport work the same and one is not better than the other. Botox is just a brand name that was well marketed and has seemed to stick to any anti wrinkle injection.
