Does Botox Work Faster in Forehead Vs Glabella?

There is no evidence to suggest that Botox works faster in one area than another.  I have found that each patient is different. 

 

 

You are correct in assuming that Botox works quicker in smaller muscles. So it does make sense to wait a full 2 weeks before deciding on the final results of your injection. That being said, don't delay returning to your doctor to have them evaluate the final results. Sometimes just a small "boost" to an area can fix problem results. Your doctor also took notes on how you were injected, so they may change the pattern of your injection based on the results you had. The key is returning to them for follow-up!
