Thank you for your question. The number of units is referring to the amount of Botox used and does not reflect the number of injections.

Botox units and injections
Good question as this can be confusing especially with the different pricing models among different providers. I would think of botox strength (and cost) in terms of units. 10-50 per side for masseter injection is a reasonable dosage range, with the higher end of that being more common. The number of injections is simply how the provider chooses to spread out the prescribed number of units, as it is rare that you would want all 50 units put into one portion of the muscle, and this typically does not have much to do with the cost. The most common pricing model is a certain amount of dollars per unit injected. That being said, some providers will charge a flat fee for certain areas to be treated.
Botox and Masseter Muscle
Botox shot is typically 2.5 units
Botox pricing is usually based on the total # of units of Botox injected. Most patients for masseter injections require 20-25 units per masseter muscle. The # of injections is not relevant to the pricing.
Units versus number of injections for Botox
Thank you for your question pokemongoo. The number of units and number of injections is a common cause for confusion for many people. It is important to understand how Botox is prepared. It comes as a powder dried in 100 units or 50 unit vials. The manufacturer recommends reconstituting 100 units in 2.5 cc of saline. In this way each 0.1 cc contains four units. Different amounts can be injected. For example an injection can be 0.1 cc, which would be four units. Alternatively a larger injection of 0.2 cc would provide eight units. A common technique to treat the masseter is three 8-unit injections per side, for 24 units per side, 48 units total. Some injectors prefer to make more injections with lower dose per injection; this works well to spread the Botox and increase precision. The most important thing to remember is to not get caught up with the number of injections. It is the number of units that is important. Please consult with a doctor for specific recommendations. Good luck!
