The nurse told me she had given me 20 units, but she only gave me 4 Botox injections. Is that normal?
How Many Botox Injections for 20 Units?

Botox injection sites with 20 units
If you had Botox injections for your frown lines, it would be appropriate to inject 20 units into four sites, depending on your muscle movement. After 12 days, you will know if it was the appropriate dosage for you and you could have more Botox if indicated.
The Number of Botox Injections not as Important as the Person Injecting You
Sometimes we will use 5 injection points and sometimes 3 or 4 or 6, depending on the need – and then we will inject the appropriate amount of toxin into each site. Sometimes you may need 4-5 units into a certain area and sometimes you may need a little more or a little less – that is why going to the proper injector is key.
Find a board-certified dermatologist or plastic surgeon – and enjoy the toxin for what it does to the lines that concern you.
There is no normal.
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.

It may be fine
Botox can be diluted to different concentrations depending on the physicians preference and the effect that is desired. Overall the most important issue is the total number of units given and the placement of the injections. If you were being treated between the brows for frown lines it may be perfectly normal to receive 4 injections for that area. It would be a little more unusual to only have 4 injections to treat crowsfeet.
However, the bottom line is the end result. Botox can take up to two weeks to fully work. After two weeks, if you are happy with the result, than things are great. If you are not satisfied with the result, a different injection pattern or dose may help.
Hope this is helpful.

Sounds appropriate for Botox
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.
