Dysport is the second FDA approved neuromuscular toxin approved for wrinkle reduction in the glabellar (between the inner brows). It is manufactured by Medisys, the company which makes Restylane and Perlane.
The units of Allergan's botox are not equivalent to those of Dysport.
To compare and contrast:
Dysport generally "sets up" in 24-48hr. Allergan's product requires 5-7 days.
Treatment of the forehead, 11's, squint lines requires average 25-37.5units (allergan) vs 100+ (dysport).
Dysport does spread out or diffuse better than Allergan.
Duration of action is comparable in both products, averaging 3-4 months.
Price is comparable.
Hope this helps. good luck.
