I had Botox for the first time, zero effect at 7 days. Does that mean I'm unlikely to see anything happen from now?

I always tell my patients to wait a full 10 days to see the results of any Botox injections. I find that most patients need a minimum of 20 units to the glabella to see significant improvement in that area.  Some patients will require 30 or even 40 units to that area for total cessation of movement. All the best,

Thank you for your question. I agree that you need to wait two weeks to determine how much effect you get from your first Botox injections. If you are not satisfied with your results at that point, schedule a follow-up with your injector to see if additional Botox needs to be administered at this time. It is not unusual for injectors to use minimal amounts on new patients and then do a “top off” two weeks later to achieve an optimal outcome.

Thank you for sharing your question.  For most patients results can start to be seen or felt 3-5 days after treatment with full effects by 7 days.  Unusual to not have any improvement at 7 days but wait another week and then revisit your injector to discuss results.  

Dear Considerate774, Thank you for your question. Although you may need a touch up dose of botox, it is important to wait the 2 weeks for the final result. It is almost always better to be conservative the first time around as you can always add more. I suggest following up with your skilled licensed injector. Best of luck to you!

Botox often takes up to 2 weeks to have full effect, though often patients will begin to see some changes at 1 week.  You may be not seeing enough of a change due to the dosage that you received.  This area is often treated with 20 or more units, so 15 units is a low dose. 
Also, you didn't indicate whether you were male or female in your post.  Men also often require an even higher dose, as they usually have increased muscle mass versus women.
I recommend waiting until the 2 week mark and if you are still unhappy with your result, go talk to your injector.

Botox results take up to 1-2 weeks and last up to 3-4 months in new areas of treatment. I recommend getting a formal evaluation with a cosmetic dermatologist. Dr. Emer

Although you should have seen some changes after your Botox injection 7 days ago, I would wait another 7 days before calling the treatment a failure.

Although 15 units may seem like a great deal of Botox, depending on your particular anatomy it is actually on the lower end of the spectrum in terms of dosing for glabella lines.  If you have very heavy corrugator and procerus muscles you may require more Botox.  Also, if it is your first time getting Botox, your provider may have not explained to you that Botox will help with decreasing movement between your eyes however, Botox will not get rid of deep wrinkles between your eyes if they are already there.  Wait another week and follow up with your injector.  If they are reputable they should be able to get the results you are looking to achieve.

I would suggest waiting 2 full weeks.  Then see your injector if you do not see results.  With 15 units, you should definitely see at least some effect by 2 weeks.  

Thank You for your question.  Botox works differently on all patients and it 100% takes up to two weeks to set so be patient and I'm sure you will have a great result.  If then you are unhappy, I suggest you return to the provider.Good LuckDr. Elliot Heller
