When Will I Notice the Results of the Botox?

In general, a patient should notice some effect of the BOTOX Cosmetic within 4-7 days of it being injected. However, this time may be shorter in some individuals. The complete effect is generally seen by 14 days after the date of the injection.
One of the most frequent misconceptions is that BOTOX Cosmetic will work immediately. It is important to understand how BOTOX Cosmetic works.
After BOTOX Cosmetic is injected into the muscle, it takes time for it to bind to the receptor responsible for sending the signal to release a chemical that results in muscle contraction. Until this binding takes place, the patient will not see an effect. This process takes a different amount of time in different people.
I recommend that all patients be seen two weeks after being injected with BOTOX Cosmetic. This will allow your physician to critically evaluate the results. If you are pleased, it will allow the physician to know this so he/she can repeat the injection technique in the future. If you are not completely satisfied, a dose adjustment ("touch up injection") can be performed to meet your expectations. This will also allow your physician to adjust his/her technique in the future.
Remember that BOTOX Cosmetic will not remove lines or wrinkles that are already etched into the skin. For this, one should consider skin resurfacing (e.g., chemical peels, laser, dermabrasion) and/or injectable filler materials (e.g., Restylane, Juvederm).
Be sure your physician has the proper training, credentials, and experience. Communicate your goals before your injection. This will allow your physician to meet and hopefully exceed your expectations.

It is very common for the Botox to take 7 to 10 days to start working.  Sometimes it works within 2 days.

It takes 2 to 4 days before the weakening of your muscles begins. You will see the final results of your treatment 10 to 14 days after the procedure. I ask my patients to come back after 2 weeks to check on their progress. So give it another week and you will start to notice the difference. Good luck.

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

Thank you for your question, jenniferdrichards! Botox can take up to 2 weeks to see full results, although you will most likely begin to see the Botox start working within 1 week.

Hi there!
Thank you for your query. It usually takes 7-10 days for Botox results to become noticeable and 2 weeks to produce maximum desired results.
Hope this helps!
Best Wishes,
Dr Rupert
