As far as anti-wrinkle treatments go Botox® is the household name, it is the original product on the market, and has become a generic term.  I was trained initially with Botox®.  However I found it slightly limiting having only one brand available for use with my clients, and I will explain why I chose to add Dysport® into my practice.  I will also explain what the differences are between the two.

Firstly “What’s the difference?”

  • Both brands work by a very similar mechanisms of action.  To keep things very simple, at the site of injection, the drug blocks the signal between the nerves and the muscle, so the muscle can’t cause wrinkles for a period of time.
  • Dysport® and Botox® units are not equal, the ratio of Dysport® to Botox® units is generally 2.5:1 (2.5 times more Dysport® units per 1 unit of Botox®).
  • The active ingredient (Botulinum toxin A) is the exact same in both medications, however the protein structure surrounding each molecule is slightly different.
  • Regardless of which product you use, full effect still takes two weeks.  The effects of Botox® are usually noticed within 3-5 days.  There are some clinical studies suggesting Dysport® can show results as early as two days. I will stress at this point that, from my experience, what is true for one client will be different for another.
  • The effects of Botox® and Dysport® both last about the same amount of time, up to 4 months.  Clinical studies have shown that the quantity of the active Botulinum Toxin A injected determines the duration of action, rather than whether it was Botox® or Dysport® injected.
  • You may have heard that Dysport® spreads slightly further from the site of injection than Botox® does.  This is a myth, particularly when applying the products recommended dilutions. However we do know that both products can spread from the site of injection.  We also know this risk is higher as the dose increases.

Secondly “Why did I choose to add Dysport® into my clinical practice?” 

  • It’s cost effective. Dysport® has a slightly lower price point to the provider, therefore those savings can be passed on to the client.  At Ivy Clinic a treatment of Dysport® can save you up to $60 per treatment.  Not a huge difference, but over the course of a year that can add up.
  • Dysport® is the second most popular choice of treatment worldwide and some clients prefer it, so I wanted to be able to offer it.
  • I have used both products myself and enjoy the effects of each.  As I said earlier, I have found that everyone is different and so what works best for one person won’t necessarily be the best for another.  Personally I find it beneficial to have both options in my tool belt.

At the end of the day there is no right or wrong choice.  Try both, preferably from the same injector, and see what you think.  Anytime I treat someone for the first time, with either Botox® or Dysport®, I will do a 2 week follow up to ensure we have achieved the perfect dose for you.

Best Wishes
