How Long Before Botox Results Can Be Seen?

Botox inhibits the communication between nerves and muscles. It does so by blocking the release of certain small chemicals (neurotransmitters) that nerves use to signal a muscle to contract. 
The onset of action of Botox varies from person to person. Botox first has to bind to the nerve before it can enter the cell. Some patients bind Botox faster because they have a greater number of these high affinity "binding sites" on their nerves. After binding to the nerve, Botox enters the cell to prevent the release of the chemical messengers that cause muscles to contract. When the muscle can no longer contract, the wrinkles soften and relax. 
Typical onset of Botox is between 24 and 72 hours, although some patients may require up to 5 days to see a result. The maximal effect of Botox occurs at about 10 days after treatment. 

Thank you for your question.  Typically Botox could take up to 2 weeks to see its full result. We tend to start seeing some improvement within the first 3-5 days.  Botox typically lasts somewhere between 3-4 months and on a average patients are receiving the treatment approximately 3-4 times a year.  The thought is as long as you keep up with your injections you will train your muscles not to make those motions anymore and it could start to last a little longer as you continue treatment.  I agree with previous answers that you should follow up with your board certified physician 2 weeks after your treatment to make sure you have received the optimal results.  You can continue to receive Botox treatments consistently every 3-4 months for years and years to come with out any increased risks. 

Thanks for this great question.I tell my patients that it could take anytime between one to two weeks.However, most patients report to start seeing some results much earlier.Best Wishes,Dr Sajjadian

I counsel patients that they will start to see something in about 3 days, then it is as good as it gets at 1-2 weeks. I like to see new patients back at 2-4 weeks to evaluate the effects. I always learn something, and sometimes a little tweak can take a good result to an outstanding result!  This yields valuable information for future treatments. The average result lasts 4 months, but everyone is different. Some people have very active enzymes and chew up the Botox in 3 months, and some people have a great effect for 6 months. I have  been using Botox for about 15 years. I don't believe that there is a limit. Some patients report a diminished effect over time, and others, just the opposite, believing that the muscles atrophy and shrink over time.  I don't know if this has been studied. For most patients, it keeps on working, over and over.  

Botox injections may not always have the same result due multiple reasons.
1-The dosage and the quality of the Botox2-Area of injection3-Skin quality
That is why it would be better to wait up to7-10 day to see the final outcome

How long Botox lasts is a patient question I encounter frequently. In short, you may be able to see the Botox taking effect in as little as 3-5 days, but it can take up to two weeks to see full results. Over time, as your muscles relax, you may eventually need less Botox to achieve your desired result. Depending on the severity of your facial lines, Botox can last anywhere from 2-6 months, but 3-4 months is the average. Multiple factors can affect how long your Botox lasts, such as: Are you a fast metabolizer? Did you receive a lighter dose of Botox because you were concerned about retaining full facial expression? How severe are your facial wrinkles? The experience of the injector also plays a part in this. It's best to do your research and choose an injector with intimate knowledge facial anatomy/structure.

Botox should begin to work around the 48hr mark. It will last 3-6 months depending on how much, how often and where it is injected. 
One can get botox as many times as they want for as long as they want. It is all dependent on what you are looking for. 
I recommend seeing a group that does a lot of botox and can offer many treatments. Many times botox is not enough to get the results patients are looking for. We have a multidisciplinary practice with myself, a plastic surgeon and my partner, a dermatologic/cosmetic surgeon. We often do joint consults to make sure patients are maximizing their cosmetic goals! At our practice only the surgeons inject. If the results are going to have my name on them I prefer to be the one injecting. 
I included a video on skin care management as that has the biggest bang for your buck as an adjunct treatment with botox. 
Hope this helps.
Best of luck

Botox is an
incredible product as it can give patients a very natural and aesthetically
pleasing result.

With Botox
patients do not see any difference the day of the injection. They may feel some tightness in the forehead
where the Botox was injected. Then over
the next week to two weeks they will see the results of their treatment.

The Botox
relaxes the muscles that cause us to make wrinkles around our eyes and
forehead. With time the muscles will
stop forming these lines. I tell
patients that even though they will see the results of their Botox at two weeks
they will continue to improve over the next couple months. As the skin has time to relax the lines will
continue to fade with time.

Please discuss
your Botox treatment with your board certified plastic surgeon.

I consider Botox or Dysport, the best investment a woman can ever make for her facial skin. The wrinkles that appear on the face are partly due to the muscles of facial expressions. Botox (or Dysport) will relax these muscles and preserve the skin. The earlier you start the better the skin will remain. Botox can be used indefinitely. It does not accumulate in your tissues, and has been used safely for over 20 years.

No expensive anti aging moisturizing cream can even come close to preserving skin like Botox does. My advice for preserving your skin is: any cheap moisturizer, sunblock, and Botox

Botox will start working anywhere between 24 to 72 hours. The full effect is seen in about  one week.

The results from Botox injections can typically be seen within a few days, with the full effects usually visible after about 7 to 14 days. As for the frequency of treatments, Botox injections can be repeated every 3 to 4 months. There isn't a specific limit to the number of times you can receive Botox throughout your life, but it's important to have treatments spaced appropriately to avoid building resistance to the toxin. Continuous treatments should be monitored and adjusted by a qualified healthcare provider to ensure safety and effectiveness.

Everyone is different but generally speaking average time for Botox efficiency is four months. After this time, you will start to recognize your old wrinkles reappearing. I wouldn't recommend you to get Botox injections earlier than 12 weeks.
You can expect to see the full benefits 14 days after your treatment. Your skin will look smooth and fine lines and deep wrinkles will diminish. Best wishes.
