How risky is it to have an ENT Dr. do cosmetic Botox injections for the crows feet, the 11s and forehead?

I recommend seeing a board-certified Doctor who is an expert in Botox injections. It will take 1-2 weeks for final results with Botox. Best, Dr. Emer

If your ENT does it regularly, and gets consistently good results, it should be fine.  In fact, ENTs have been using Botox prior to its use in the cosmetic arena.  Good luck!
