Botox Q&A: How Long Does Botox Last and What Makes the Effects Last Longer?

Question – How long does Botox last? What determines how long it will work for me?

Answer – In most patients, Botox lasts between 3-4 months. However, there’s quite a bit of anecdotal evidence suggesting that it’s possible for patients to achieve results that last up to 6, 9 or even 12 months after consistent, long-term and properly-administered use of the Botox product.

In other words, what determines how long the effects of Botox lasts is:

1. the dosage (and whether or not it’s been properly diluted)
2. the duration & consistency of use
3. the skill/experience of the injector or surgeon who administers the injection

The x factor within the “consistent, long-term and properly-administered” conditional I included is, of course, “properly administered”. After all, consistent treatments over several years will matter very little if the wrong amount of Botox has been injected imprecisely/incorrectly. That’s why 2 of the 3 factors explored in this post address it (re: ‘dosage’ and ‘skill/experience of the Botox injector‘).
