Since Dysport (formerly known as Reloxin) was approved a few months ago, I’m still searching to see how effective it is but since it contains the same main ingredient as Botox, I can’t imagine anything is really different.  Dysport was developed in New Zealand and requires an authorized person to inject the bacterium into the area of choice.   The claim that contrasts from Botox, at least from my experience, is Dysport takes about 20 minutes and provides immediate results.  Botox can take a few days to a couple of weeks to show full benefits which to me, is a plus.  Botox lasts approximately three months and results are different for different people but for me, three was fairly accurate.

Dysport, like Botox, was granted for approval for both cosmetic and therapeutic use.  The FDA does require both products to list warnings that botulinum based products can spread from the injection site to other areas in the body thus producing botulism poisoning.  I just found a site that is advertising one vial at $449.99 which is much higher than Botox.  As of June 15th, Medicis started shipping Dysport.

Here are a couple of interesting quotes I found:

SKINTASTIC Medical and Surgical Rejuvenation Center medical director Jeffrey Adelglass said: The major benefits of Dysport to the cosmetic patient will be that there are fewer injections, and treatments hopefully will last a little longer.

Russell Katz, director of the FDA’s Division of Neurology Products. Botulinum toxin products have benefits, but can cause serious health problems and it is important that anyone who administers or uses these products understands these risks.
 
The following link provides information if you are interested in participating in a clinical trial where Dysport is used.  Although the trials do not include wrinkles, there are trials recruiting for various health issues such as overactive bladders, clubfoot, migraine headaches, urinary incontinence, strokes, chronic pelvic pain and a couple of other diseases.
 
 
One final note, Australian doctors warned doctors to not treat pregnant women due to a potential effect to cause birth defects.  Botox has the same safety concerns.
