A new weapon in the battle against facial wrinkles has emerged with the approval of Dysport®, a muscle-relaxing injectable that may pick up where Botox® Cosmetic leaves off. Though the two are very similar, the fact that they are not identical may be significant.
Dysport®, recently approved for use in the U.S. by the Food and Drug Administration (FDA), is a botulinum toxin Type A injectable, like Botox® Cosmetic. Both are injected into facial muscles that cause wrinkles, to paralyze those muscles and smooth the skin.
Some patients develop antibodies to Botox® Cosmetic, so that it eventually loses its effectiveness in repeated treatments. Some cosmetic surgeons hope to switch those patients to Dysport® for further treatments, though they caution that antibodies to the latter may develop even more rapidly.
In testing so far, Dysport® seems to show results sooner than Botox® Cosmetic, in a day or two instead of three to five days. Dysport® results seem to last longer than the typical three months achieved with Botox® Cosmetic. Since data available for the new product are limited, claims vary widely from extra weeks to extra months.
There is almost no cost difference between the two products. The price for Dysport® is about one-third of that for Botox® Cosmetic, but the former is about one-third as strong, so requires three times the dosage.
