How Many Botox Injections for 20 Units?

Dear Iselita
There are any number of way to dilute BOTOX. However most standard dilutions vary between 2.5 to 4 milliliters of saline. This produces BOTOX solutions with a concentration range of 25 units to 40 units per milliliter. Rarely an injector may use 1 milliliter of saline to reconstitute a 100 Unit vial of BOTOX. In this circumstance, 20 units of BOTOX would be contained in just 0.2 ml of saline. However, it is unusual for injectors to work with such concentrated BOTOX solutions. However, 0.2 ml of volume could easily be administered in just four injections.
I think what you are really asking is if you are getting less BOTOX than your are being told you are paying for. The answer to this is a resounding maybe. This type of deceptive business practice is very common. After all it is hard for you as a consumer to actually know what you are getting. Here is the clue: How long does your treatment last. Smaller doses of BOTOX wear off much faster that appropriate doses of BOTOX. A twenty unit treatment should provide benefit for at least 2 months. If you only seem to get a couple of weeks of benefit, it is time to find an ethical cosmetic surgeon like Dr. Cohen.

Yes that is normal depending on the dilution that he/she used.  You can inject more than one unit of botox at a time.  

Thank you for your question! A total 20 units of Botox Cosmetic injected via 4 injections sounds appropriate. The concentration of the solution would be 5 units per 0.1cc. Most plastic surgeons and dermatologist use concentrations of either 2.5 units or 5 units per 0.1cc. There is no cosmetic difference with the concentration. Botox Cosmetic takes a little bit of time before you see results. Wrinkle improvement starts within a few days, with maximum aesthetic rejuventation by 2 weeks after injection. Touchup Botox Cosmetic injections are sometimes needed to achieve the best results. Best of luck!
