Average Length of Time Botox Lasts?

I expect botulinum toxin to last at least 4 mos in my practice.  From there it seems to slowly lose it's effect, which means some patients come in very early and therefore assume it's a 4 month drug, and some wait until the total effect is gone and they get closer to 5 months.  I have used dysport and xeomin as well, and don't feel like they hold up as long (dysport might be comparable only in the crows feet).  

I would also add that 8 weeks is very short.  There are two reasons that might be responsible for such a short duration.  One is that you need more drug to drive a more conventional 3-month-plus duration, and the national guidelines for each region of treatment  describe an effective range that physicians typically work within.  For example, your glabella typically requires 20-30 units, with more drug expected to improve duration.  The second reason is your activity level. Patients with aggressive workout regimens, or very active lifestyles, or frenetic personalities all seem to break down the drug more quickly. I have tried to get my trainers and marathoners to durations beyond three months by increasing the dose, and it doesn't always work.  My suggestion is to educate yourself on your specific dose, and consider a higher dose.  If that still doesn't work, an anecdotal trial of a different neurotoxin is worth it before abandoning neurotoxins altogether. 

While Botox, Dysport, and Xeomin start kicking in around day 2, they typically don't reach their max benefit until around day 14.  Botox, Dysport, and Xeomin generally last 3-4 months, but is highly patient dependent. Onset and
duration may vary from patient to patient.  Perhaps you need more product injected each treatment or you may consider trying Xeomin. I wish you well!  Be sure you are seeing a core" Botox injector (facial

plastic surgeon, plastic surgeon, dermatologist, or occuloplastic
surgeon). This is because we all have a keen understanding of facial
anatomy and the effects of injecting Botox/ Xeomin/ Dysport and fillers
in different
regions of the face. An in-person exam is absolutely necessary in your
case to check your dynamic facial expressions, evaluate past treatments, and discuss your
concerns/ expectations prior to developing a future treatment plan. Be sure
you are seeing one of us, and I wish you well!

Thank you for your question. Botox and Dysport can last up to 3 months or even longer, but sometimes can last shorter than 3 months. Everyone's metabolism plays a big role and there are people like yourself who's very active and the Botox last only for 2 months. I hope this helps.

The effect of Botox should last at least 3 to 4 months -- but will last for longer or shorter periods in approximately 10 percent of the population. These differences in length of effect can be accounted for by differences in 3 factors: 1.) the quality of the product itself, 2.) the injector's dilution and injection techniques and 3.) the patient's genetic makeup and physical activities following injection.Product factors that can effect longevity:1. Damaged Botox molecules: Occasionally, and very rarely, there is a "bad batch" of Botox that just isn't as effective as it should be. This can happen whenever there is an error in the purifying process where the Botox molecule becomes damaged and therefore less effective. The only way your injector is going to figure out if this is the case with a certain batch is if people like you report instances when they believe their Botox has not lasted as long as it should, or as long as it usually does.2. Different forms of the molecule: There are other products on the market that work very much the same way as Botox (as a class, they are all called "neuromodulators"). The brand names of these other products are "Dysport" and "Xeomin". Although these are close to being composed of the same molecules as Botox, the slight differences between these forms can make a significant difference in effect or longevity. However this difference is determined primarily by individual patient factors (see below).Patient factors that can effect longevity:1. Individual differences in metabolism: Since Botox is a molecule with structural components found in nature, each person's body metabolizes it, but does so at different rates. Hence some people get rid of the Botox and it's effect sooner than others. Some people are even immune to or can develop an immunity to it's effect -- and therefore get little or no effect. These metabolic factors are genetically determined. Therefore you can't do anything about this except try another similar (but different enough) product like Dysport or Xeomin2. Individual sensitivities to the different neuromodulators: Dysport and Xeomin are essentially the same as Botox, with minor differences in their molecular structure. However these minor differences may make a big difference in how long each product lasts. So if you aren't getting at least 3 to 4 months effect from your injections, then switch to and try one of these other neuromodulator products. They may last longer AND you might find that they are less expensive.3. Use of treated muscles immediately following injection: If the treated muscles ARE used repeatedly during the first 2 to 4 hours following injection, it's possible that the Botox will have a BETTER and LONGER lasting effect. This is, as far as I know, not a certainty, but it certainly will not hurt to do this for a while following your injections, just in case.Injector factors that can effect longevity:1. Number of Botox "units" injected: Ultimately, what is most important when determining the worth of your Botox treatment, and the expected effect from it, is HOW MANY UNITS ARE BEING INJECTED. Don't just get an "area" treated without asking how many units are being used. Less units may give you the same initial result, but it just won't last as long.2. Dishonesty: Depending on the volume of water (actually "saline") that is used to reconstitute the Botox powder, there can be a different number of units of Botox molecules in the same volume water -- and each injector is free to add as much saline as they want. So just paying attention to how much fluid is being injected really tells you nothing. Therefore, you really can't be certain of how many units you are actually getting in a treatment unless you personally watch the injector reconstitute the Botox, then do the dilution calculations in your head, then pay close attention to how much volume is being injected. Some profit-hungry and unscrupulous operations will take advantage of your inability to tell how many units are actually being given by simply lying about it, and giving you fewer than they are charging you for. If you go to or come from another clinic and you were getting better longevity from the same number of units, chances are that the Botox was being over-diluted at the "bad" clinic.In any case, I wouldn't assume anything unless you have had a bad experience at the same clinic more than once. If you do, then you know it's NOT the product that's the problem; It's either you or the injector. The next step is to go to another clinic and see if you get the same short results WHEN USING THE SAME NUMBER OF UNITS. If you do, then it's an injector dilution problem. If you get the same bad results at any clinic, then your individual reaction to Botox is the problem and you should try one of the other products (Dysport or Xeomin).This is kind of a long-winded answer, but it's not an easy answer for each individual to figure out since any of these factors can be the cause or at least contribute to a shorter duration of Botox effect.

Botox usually last 3-4 months and dysport about 1 month longer in many patients give or take a month or two. Xeomin is so new i can't tell you from experience yet. Sincerely,

8 weeks is not the average duration, but it's not an uncommon length of time.  The strength of the muscles treated, patient's physiology, and the dosage of Botox used can all factor into the time a treatment lasts.  

If you'd like to see if you can extend the time between treatments you can try increasing the dosage slightly, or trying Dysport.  

Botox usually lasts 3-4 months, but this varies for each person and also depends on the area injected and number of units used. If you are noticing the effects of botox wearing off sooner than normal, then your injector may have not used enough units to get the result you want. Sometimes it takes a couple of treatments to determine exactly how many units are appropriate for you as not each person is the same. Hope this helps!

Botox and Dysport typically last 3-4 months, but this varies from patient to patient. Sometimes, it's a little longer, and occasionally, a little less. Discussing this with your provider will help determine whether you may or may not need more product in general, of if you just are one of the few with a shorter duration.

Botox and Dysport last around 3 months on average, and this can vary depending on the patient. Dysport may sometimes last slightly longer. I would recommend speaking with your provider, as they may suggest an increase in dose. I hope this helps, and I wish you the best of luck. 

I would say that the average length of time that the effect from Botox and Dysport lasts for cosmetic purposes is about 3-4 months.  It can last up to about 6 months in some people and some people find that it starts to wear off after about 2 months.  When it does start to wear off at 2 months, there should still be a partial effect for up to 3-4 months though.  I would agree that it's possible that a higher dose could give you longer lasting results.
