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 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!

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 duration of action ranges between 3-6 months

When you request a Botox treatment, you should probably ask how many units you are receiving and how the bottle was reconstituted or mixed. This info will allow you to predict how long the blockade will remain. For individuals who have a moderate thickness of their scowl muscles the blockade can be 3-4 months. Other individuals whose forehead lines are very fine can occasionally get up to 6 months. It also depends on how much you exercise. I have extremely fit patients who are "gym rats", doing hard cardio 5-6x/week. The uniformly report that the longevity of botox is lower. Good luck.

Botox Duration

The length of time that Botox will last depends on a number of factors including:

  • How it is mixed
  • The patient's physical responsiveness to the product
  • The method that Botox is injected
  • How it is stored

For most patients, it will last 3-4 months.

How long does Botox last?

The average length of time that Botox remains effective is 4 months. That said, I have a few patients who swear it wears off after 2-3 months and others who see the effect for more like 5-6 months. 

Which category you fall into can depend on how strong your muscles are, how diluted the Botox is when it is mixed, and how long you have been getting Botox. With regular use of Botox over many years (meaning you don't let full muscle movement come back before getting more), your muscles may weaken, and some patients can either use less or go for longer periods of time between injections.

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.
