Post Botox 11s Lines Still Slightly Appearing, How To Treat This?

Either add a little more or use a filler like Restylane. Or both. Return to your chosen injector, I hope it was a doctor. 

If your Botox was only done in the last few days, you may get more muscle relaxation during two or more weeks after the treatment.  Therefore, you may see further improvement.  Some people have very deep lines because they have scrunched the skin together so many times over so many years that the lines stay etched in the skin for a while after the muscles do get relaxed from the Botox.  It may take several sessions of maintaining the Botox treatment so that the muscles never "wake up" and allow the skin to continue to not crease and let the lines fade away.  If there is a big social function coming up for which you want to look your best and can't afford the patience of time, then sometimes, a small amount of not-too-thick a filler can be used, such as Restylane or Juvederm in this area to fill out the line.  It doesn't mean that the filler would have to be repeated when it wears off in a year or so just as long as the Botox treatment is maintained every three to four months.  Injections of fillers in this area has a risk of circulation compromise and there have been reports of big scabs forming and even scar formation when very thick fillers or fillers injected with high volume were placed in the glabella so speak to your dermatologist or plastic surgeon about this prior to having the injections. The advantage ofusing Restylane or Juvederm in this area is that if there is a problem, the filler can be dissolved by injecting an enzyme, hyaluronidase.

Since the vertical lines between the eyebrows are caused mostly by hyperactivity of the underlying muscle, treatment with a relaxer like Botox or Dysport is the first step. However, if they have been there a long time then the lines become "etched" into the skin. So if you still see a line there after the Botox has taken effect, the next step is a dermal filler such as Juvederm, Restylane, or Radiesse.
