I just had Botox injected in my forehead 3 days ago. Are the indentations in my forehead permanent?

This is difficult to answer without pictures. It can take 1-2 weeks for final results with Botox. Venus legacy can help soften results. If you're concerned, I recommend following up with your injector. Best, Dr. Emer

Botox relaxes muscles and would not cause "indents" however it is best to follow up with your injector if you are concerned.

Dear annabelleorme,
in some cases there might be some swelling after the Botox injections. It usually isn't that severe and it resolves within a few days or weeks.

Botox will not cause you have to have 'dents' or other permanent irregularities in your forehead. Unless something else (skin condition) is going on- it's not caused by the botox as long as the Botox was constituted in the right solution etc. 
Hope this helps and God Bless!

Thank you for your question. BOTOX® should not create permanent indentations in the skin. It’s possible that the indentation is resulted from swelling in the surrounding area and will fade within the following few days or week. Any effects from the BOTOX® will also eventually wear off after about 4 months, so if you’re unhappy with your results, rest easy knowing that they aren’t permanent. Good luck!

Without photos, hard to say what's up, but Botox should not cause indentations. If the issue has not resolved on it's own, make an appointment to see your surgeon. Best of luck. 

Hi,
Is there any way you can upload some photos please?
Also if you can give us some more update.
Thank you!

Hello, I hope by now it has improved and this response is moot - but Botox should not give an indentation anywhere, and if there is surrounding swelling or bruising it should resolve over a period of a few days. If there is still concern return to the provider who administered the botox to discuss further.

Hello, and thank you for your question. Without a photo, it is difficult for me to give you an in-depth analysis of your situation. However, Botox injections should not leave indentations because it relaxes the muscle. I would follow up with your injector to discuss further treatment options.
Best of luck

Hello annabelleorme,Thank you for your question although photos depicting what your have described would be helpful but not a substitute for an in person evaluation with your injector. Botox causing "dents" not likely however any changes noted from Botox will go away as it wears off in 3-4 months. See your injector to discuss further.
