Does Jeuveau require more units than Dysport?

Hello, and thank you for your question. Jeuveau and Dysport have different dosing units. Jeaveau is often dosed in 2-4 unit increments per site, while Dysport is 5-10 unit increments per site. So if you had more units with Dysport, that makes sense in comparison to Jeuveau. If you are ever concerned or question unit dosing, be sure to ask your provider to clarify for you. The effect can be the same even though dosing is different, but some people respond a little different to each brand of neurotoxin.

The number of units of Jeuveau is less than the number of units of Dysport to obtain the same result. I would consider 50 units of Jeuveau to actually produce more effect than 60 units of Dysport.

Jeauveau and Dysport units are measured differently. For every one unit of Jeaveau you need to use three units of Dysport. So, your old Dysport dose was the equivalent of 20 units of Jeuveau (10 on each side). So using 50 units of Jeuveau (25 units of Jeuveau on each side)will likely result in weakening the masseter more. This could potentially lead to a more noticeable and longer lasting result.

The different brands of neuromodulator have unique units which are not directly interchangeable. It is likely that the injector who did your Dysport was telling you the units in "botox units" so as not to be confusing. The conversion rate is 3 to 1, meaning that 30 actual Dysport units would be equivalent to only 10 units of Jeuveau. 10 Dysport units would not be enough to treat a masseter muscle. So, again, because the math and the concept on this are confusing to clients, we tend not to "talk" in actual Dysport units but rather take them and multiply by 3 and report it as if it is more like the other brands units.

The unit comparisons between Jeuveau and Dysport aren't straightforward due to differences in formulation, potency, and units of measure. However, as a general rule, Jeuveau is about twice as potent as Dysport, meaning your treatment of 25 units of Jeuveau on each side of your jaw might indeed offer a comparable, if not potentially greater, effect than your previous 60 units of Dysport.
The comparison you've made translates to approximately 100 units of Dysport when considering Jeuveau's potency. That said, individual responses to these treatments can vary widely, so it's essential to monitor your results and discuss any changes or concerns with your healthcare provider. They will help adjust your dosage to find the optimal amount for your desired outcome.

One unit of Jeuveau equates to about two and half units of Dysport. So based on your description, you should have an increased effect from your Jeuveau treatment than what you had with Dysport.
