When can additional Botox be added if 11s are still there?
The dose depends upon which toxin was used. Dysport tends to require about 2 1/2 times the number of "Botox units." 20 units of Botox is typically adequate for this area but depending upon the muscle volume it's not uncommon to require more. You should be fine with the addition of additional units at this point if you still have too much movement.

Botox Touch Up
There can be many variables, but when I personally get Botox or when I inject my patients I begin with 20 units and touch up with another 5-10 units after 10 days. I do not think this is a problem in the normal healthy adult patient.

Filler Might Be Recommended
there is no danger to adding additional units to the glabella, a total of 45
units is a larger than typical amount used in that area. I
would advise waiting up to 4 full weeks to make sure that the 20 units
are not working. Adding anadditonal 10-15 units may be more appropriate than 25,
depending on the strength of your glabellar muscles. The
repetitive motion of those actively moving muscles are what has caused the
lines to form between your brows, and botox helps to diminish that muscle
activity, preventing and furthering worsening those lines. If your
lines are very prominent when you are at rest without frowning, is it unlikely
that adding more Botox will help. A dermal filler such as Restylane or Juvederm
may be more effective in reducing those “static” lines that are present all the
Botox Touch up
In my experience in average frown lines, Botox will work well with a dose of 10units provided it is injected on the right position of the involved muscles. Rarely, a higher dose is required for those patients with massive and strong muscles.
Since this is your first experience, drug resistance is out of the question.
If these are permanent frown lines, you will need concomitant injection of fillers.
However, if you are looking for a touch up, 2 weeks is just about the right time for you, either with the same dose or lower.
Botox touch ups
As long as there is good technique and experience on the injector's part, there is no concern with injecting more botox units to get the desired effect at 2 weeks. Twenty units is a standard starting dose, and it is common to add more toxin at 2 weeks to even things out or to get so stronger effect. I have safely used twice the standard dose in the glabella for men or in people with strong glabellar muscles. Everyone is different, which is why I stronger suggest seeing an experienced physician injector.
There shouldn't be a problem with a Botox touch-up 2 weeks after the initial injections. The amount of Botox needed for a touch-up is really dependent on how much you are wrinkling after the initial treatment.
Botox and results.
20 units of Botox is a good standard dose. It is also a good starting point for someone who was never had anything in the glabellar region before. I often try to differentiate what to expect in terms of 11's deepening while you frown versus 11's at you see when you're not frowning at all. Botox may not help much with static lines, that is to say the lines that you see when you Are not frowning. For this I often use fillers in conjunction with the Botox.
If you still feel like you have a lot of frown movement after a couple weeks, you can always add more Botox. I would also make sure that you go to a place that is well qualified to do Botox injections. People will dilute Botox differently at different places and the technique is important so that you are injecting the correct muscles to get the desired result. If you still see movement at the frown region, then you can always add more Botox to soften these lines.
Our typical dosage is 25 units per area-(unless the wrinkles are more pronounced and deeper) you should be able to go back for additional units at this time. Your PS can determine how much would be effective.
20 units of Botox were not effective on my glabellar lines. Any concerns about touching up with 25 units, 2.5 weeks later
You may have been under dosed, If you have very strong muscle movement to start, you will require more units of Botox to see full result, scheduling a follow-up consult with your provider would be best
20 Units of Botox
Botox is extremely popular and reliable. Twenty units was a very satisfactory dose for your glabella. It typically takes 5-7 days to start to see the result. We would not consider a touchup until two weeks have passed by as it should have certainly taken effect by then.
Occasionally, there can be a bad vial which doesn’t have the potency. The other reason for the non-effect is it is possible the product was not injected directly into the muscle.
Different practices vary on touchup charges. You should have a good understanding of that before you have your first dose. Certainly, time wise though in answer to your question, it would be appropriate to touch up now. I don’t know that an increase in the dose to 25 units is necessary. I have never heard of a patient being resistant to Botox. More likely, it is one of the two causes I mentioned above.
