My 11s just won't go away! The issue is a pucker. The 11s are not etched into the skin as of yet

There are three frequently used neuromodulators.  Botox, Xeomin and Dysport. All three work about the same for most people but for 10- 15% of people the Botox doesnt work as well.  For those 10-15% of people Dysport works much better.  I recommend you give the Dysport a try. 

I would go back to your injector to address your concerns, I would wait a whole 14 days to see the results of the treatment. Extra botox might be needed or some filler to help the area if the wrinkle is very deep. 

Good question. For the glabellar area if the wrinkles are now static and in skin I recommend using regular botox- inject botox when even slightest of muscle action comes back. Try that for few times and if it still doesn't soften the wrinkles then add filler and that should do the trick rigth away. Just make sure you follow up with botox regularly so it doesn't come back.
