How Long Does Botox Last?

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

MANY factors determine length of Botox effectiveness.


Botox works by irreversibly binding to receptors that send nerve signals for muscles to contract. But, since your body makes new receptors and neurotransmitters all the time, each patient will have different lengths of effective paralysis. 2-6 months is the range; average is 3-4 months. But wait, there's more!

To complicate the matter further, Botox (and Dysport, another company's botulinum toxin) is a labile protein, meaning it is sensitive to heat, excessive agitation, and time. Careful reconstitution, use while fresh, and keeping it refrigerated is essential. Beware offices or spas that advertise Botox days (especially if it's Friday)--they are simply trying to use up their reconsituted Botox so it won't sit over the weekend and lose effectiveness. Particularly beware of Monday morning Botox in such centers!

Then there's the skill and accuracy of the injector. Since Botox works where it's placed, simply shooting in a blob of liquid Botox in the general vicinity of the target muscle is a waste (of your money)! The most experienced injectors are plastic surgeons who actually operate on the target muscles in patients having forehead or brow lifts, facelifts, and eyelid surgeries. In my humble opinion, non-surgeon doctors and nurses can become experienced Botox injectors over time without operating on these areas, but consider who is best trained and experienced in the anatomy of the treatment areas.

The bitterness of poor quality remains long after the sweetness of low price is forgotten!

Botox Cosmetic lasts 3 to 6 months


Botox Cosmetic lasts a variable amount in each person. I usually tell my patients that it will last somewhere between 3 and 6 months.

People with heavier frown lines tend to have stronger muscles and in turn tend to see the motion of the muscle return quicker than those with less bulky muscles in the area between the brows. In some men and even some women with prominent muscles, it may only last 2-3 months.

You will typically see a return of the movement of the muscle prior to the deepening of the furrows caused by the contraction of that muscle. At that time, it is best to get back in for another treatment of Botox Cosmetic. This way you are not letting the furrows or lines to continue to worsen.

Number of Units of Botox needed? "Depends"


Botox can last typically 3-4 months. The results may longer-lasting if more units are used.

The number of units not the volume injected that has direct correlation with the effectiveness of your Botox injections.

Your  Plastic Surgeon can also create longer lasting results if you have these muscles injected regular lay. This is because the Botox will have more impact on the muscles that are still not fully active. Also, you learn to animate and use different muscles. This also makes your result more pleasing.

Hope this is helpful.

Botox duration depends on patient and chronic usage


Botox generally last 3-4 months but this is not entirely accurate.  Patients new to Botox will generally start to see a return of paralyzed muscles at 6 weeks.  I recommend a touch up for new users at about this time.  After the touch up they generally get 4 months of effect.  I generally recommend every fourth month treatments for the first 2 years.  Once the muscles have but habitually paralyzed it will take less Botox and less frequent injections.  There are many patients who only get Botox twice a year once they have been using the product for many years.

How Long Does Botox Last?


When injected properly by a board-certified dermatologist or facial plastic surgeon at an acceptable dilution and with proper technique, Botox should last about four to five months.  Occasionally it may last a little longer than 5 months, but it should last at least four months. We offer all our Botox patients a courtesy follow up visit at 1-2 weeks after the initial treatment to check the areas and see if any additional Botox is needed (at no additional cost). Patients really appreciate this. Click on the link below for before and after photos of patients receiving Botox for dynamic wrinkling.

Botox duration


The duration of the patient's Botox treatment varies witheach patient. I find the average is 3 to 4 months in most patients. It can vary by how many units you got during your treatment and how fresh your Botox product is that is used in your treatment. It can vary if the product was just mixed that day or is several days old. I always use fresh Botox that is mixed on that treatment day.The Botox starts to lose its potency after a few hours. It can also vary by how strong the muscle is that is being treated. Often times if you continue your treatments they start lasting longer over time.

Botox treatments in the arm pits for hyperhidrosis often lasts 6 to 8 months.

Botox lasts until you want more


Hello! Initially getting injected, most patients notice movement resuming 2-4 months later. However, the cosmetic effects do not simply dissolve overnight, and your skin condition and muscle strength, as well as habits like scowling, impact the longevity or at least dictate when you will likely want more. The longer you use Botox, the longer most patients can go between injections. Keeping up with the injections on a regular basis also usually means less Botox will be required at the next injection (if your muscle is still slightly weak). Good luck!

How long Botox Lasts


Botox and dysport typically last about 4 months however I have seen cases that lasted only 3 months and one case lasting9 months .if someone has better developed muscles or if not enough product was used it could lead to less of an effect of the botox or of the dysport

Botox and Dysport duration


I have found that when my patients first start using Botox or Dyport, they typically return for treatment about every 3-4 months. However, with time, they are able to stretch out their injections to 6 months or more as they retrain themselves not to make the repetitive facial motions (such as frowning) which create the wrinkles in the first place. Be sure to consult with a reputable facial plastic surgeon, plastic surgeon, or dermatologist to ensure that you are being treated with the appropriate dosage, dilution, and in the correct treatment areas. Don't be afraid to ask how many units your physician is using per area.

Botox generally lasts 3 - 4 months but some results can be permanent

One truly remarkable consequence of BOTOX ® administration that I have seen over and over again is the gradual complete disappearance of deep, vertical furrows between the eyebrows (frown or 'scowl' lines). With long-standing muscle contraction, the vertical lines between the brows may become actual physical clefts or grooves in the dermis, resulting in creases that are still apparent even when the skin is spread apart tightly with a finger on each side of the crease. In such instances, the initial BOTOX ® injection will soften but not completely eliminate the deep furrow. With regular BOTOX ® treatment, however, such that the frown muscles are never allowed to fully regain their normal ability to contract, the deep furrows may gradually fade completely.
Some patients with chronic, deep furrows between the brows achieve improvement but not complete correction of these creases with repeated BOTOX ® injection. In these cases, a soft tissue filler can be used to eliminate what remains of the furrow. I have used Juvederm for this indication in a number of patients with excellent results, and for several of these patients I have performed structural fat grafting of the remaining furrow to provide a permanent correction.
Younger people, or individuals with softer lines may experience complete elimination of troublesome lines after just on treatment. Do find an experienced injector to avoid a "frozen face"
When considering Botox, schedule a consultation with a top provider of Botox in your area. The Botox cosmetic website can help you find a diamond level provider. These offices have the most experience and often can provide rebates and discounts available exclusively through the top providers of Botox.
