How Long Do Botox Toxins Stay in Your Body?

I've had botox injections for the last two years. I had a particularly strong injection last February that froze my forehead for 6 months, and I have not had any since then, and will probably never get it again.

My question is: is there any botox still in my body? It has been 10 months now--is my body clear of the toxin?

All Clear with Botox

Sorry to hear that you had a bad experience with Botox.

If your facial muscles that were injected 10 months ago are moving again then it is likely that the Botox is out of your system.

In some patients who have had Botox consistently for more than two years, there is an anti-aging effect even after the Botox has worn off. There are fewer lines, and the quality of the skin tone and texture improves.

Be well.

Botox lasts 3-4 months

I am sorry about your experience but you can relax, after 3-4 months Botox does clear out of your system. Botox stays only where injected, it does not roam through the body but attaches to the muscles where injected. Make sure you seek out an experienced injector next time and start with smaller doses.

Length of Time Botox Stays in Your Body

I am sorry to hear about your experience. Botox only stays in the body for 3-4 months after injection. Botox works by blocking signals from the nerves to the muscles. Next time seek out an experienced injector.

Botox probably gone by now

It's unfortunate that you had to experience this. It usually takes far less than year for Botox to leave your system, so by this time it's probably gone.

For a few months

Botox usually lasts for about three to four months, however repeated treatments can prolong results. After 10 months, the Botox in your probably has probably disappeared, although it may take a little longer depending on your physiology.

For most patients, botox will stay in your body for 3 - 6 months.  For patients who have used the product continually for a long period of time, the duration in the system will increase. An experienced and expert injector will create a natural look.

Botox "toxin" isn't as scary as it sounds

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Botox is a protein.  This protein actively binds to and deactivates a specific type of nerve, the ones that control voluntary muscles, sweat glands, and saliva glands.  The "toxin" description is only in the event that the deactivated nerves are important to life function, like breathing for example.  Typical volumes of Botox injected into the face for cosmetic purposes are too small to have any impact on any "life function". . .by a lot. 

Botox protein is "digested" by the body naturally over a few months.  It has never been shown to do anything except as noted above and has been in use for more than 20 years.  The most dangerous part of coming to my office for a Botox injection, is the drive to the office. . . again, by a lot.

Botox Duration

Botox is metabolized over 3 to six months.  Botox is never permanent and is completely metabolized and excreted and does not remain in your body.

The Botox binds to the receptor sites of the muscle fibers and gradually gets broken down over 4-5 months. I would not worry too much that there is any around at 2 years.

Botox leaves body after 4-5 months

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}


Botox is a medicine that is injected around your muscles to help relax them. Your muscles may take up to a week to finally absorb all the Botox. The Botox remains in your body no more than 4-5 months.
