Does Botox stop working? (Photo)

While it is rare after only 3 sessions it is possible to build up a tolerance for Botox making it ineffective. Usually this occurs after years of treatment if at all. You may want to try switching to Dysport or Xeomin to see if those work as the molecule for each is slightly different. Hope that helps! 

This is tough to answer without before and after pictures. I find it extremely rare for botox to stop working in patients. I suggest you speak to your dermatologist or plastic surgeon or try another product like dysport. Best, Dr. Emer.
