I hear this frequently from patients and thought it might be helpful to clarify.
Botox, Dysport and Xeomin all arrive to your providers office in vials that are dry. (the botulin product is dry within the vial) We all have to reconstitute the product with saline. So, really, we all dilute the product. Different providers have a variety of dilutions they prefer to work with. Ultimately what the provider and patient should be concerned with is how many units are administered to an area. A vial can be reconstituted with anywhere from 1ml to 4 ml or more. The provider then determines what volume to pull from the vial to have the number of units they want to administer.
For instance, most patients receive 20-30 units to the glabella or frown. If I am using my 1 cc dilution (which I use the most, just personal preference) and I want to administer 20 units I pull up 0.2 ml. If I was using a 2.5 cc dilution (another commonly used dilution) I would pull up 0.5 ml for the same 20 unit dose. I can obtain the same degree of relaxation with either dilution.
So, if you find there is a variety of outcomes it is not the dilution that creates different outcomes but the number of units placed in the muscle.
Hope this helps clarify what it means to dilute Botox. (or Dysport or Xeomin)
If you have a treatment that you love note how many units you received in the treated areas. That is the key 🙂
