Is 2 Weeks Worth of Botox Results Normal?

I have had Botox injections for my frown lines and the result only lasted 2 weeks. Is this normal? Why did I not have a longer-lasting result? This has happened more than once. I love the result for that short time but want to know why I cannot achieve a longer result.

Two weeks should be the BEGINNING of the Botox result.

Hi. Of course, I cannot be sure what's wrong. But if you repeatedly like the result, and it only lasts a couple of weeks, the most common cause is that your doctor is not using enough Botox. You must be getting very few units. Botox results should last a good 4 months or more, and it is dose dependent. For the vertical frown lines between your eyebrows, I typically use 25 units, and more in men (bigger muscles). Try another board certified plastic surgeon or dermatologist.... more

Botox Longevity

Dear Amy WB, Botox should last 3 to 4 months. It is dose dependent- the more botox the more muscle weakness and the longer it lasts. Botox's maximum effect is around 2 weeks and then the weakness of the muscles whould be present for 3 to 4 months, You may be resistant to Botox which is rare. You need to check on the dose, make sure that it is BOTOX Cosmetic and that the areas that are being injected are correct- ie the placement is just as important as the dose.

It's Not You

The potency of the Botox and how much is injected determines the length of the result. Many practitioners of Botox will freeze the vial if the entire vial isn't used. The problem with this is that the toxin loses it's potency. The second issue is the amount of Botox, or the number of units that are are being injected. For between the eyes, the glabellar region, I use 25 units. I just saw a patient back for her second treatment but she was still paralyzed-AFTER 5 MONTH! So 2 weeks is... more

Maybe it's you, not the Botox

While in most people Botox should last 3-4 months, there is a small subset in which the effect is much shorter. Your body may be finding ways to get around the temporary paralysis of the muscle quicker than the norm. You mention that this is not the first time this is happened. If you have had the same result with different injectors, then the you probably fall into that group mentioned above. If you have been using the same injector each time, I would switch injectors. Maybe the Botox is... more

Heck no!

Botox is rated to last for 6 months.  I have seen results lasting between 4 and 7 months.  Two weeks is not at all normal.

Botox effect should last 4 to 6 months

Dear Amy The only reason you BOTOX you last for 2 weeks would be inadequate dose. Someone is pulling your leg regarding the treatment they are providing for you. This is a good time to review what makes a legitimate BOTOX injector. First, make sure that you are being treatment by a licensed physician. If you are not treatment by the doctor, the doctor should have examined you at the time of your treatment and the person doing the treatment should be a physician assistant or a... more

Botox Lasting Only Two Weeks

Hi Amy, Botox would not be the number one facial cosmetic treatment if results lasting only 2 weeks was the norm. Either not enough Botox is being used, or it is not being injected into the muscles properly. I hope that you are not spending much money. Sometimes "you get what you pay for". See your injecting physician for a higher dose, or seek out a new physician injector. Be well and see you in two weeks. Dr. P

How many units are you getting?

Hello Find out exactly how many units you are getting. Botox results are dose dependent and should last a lot more than 2 weeks. Some practices advertise Botox "by the area" . That means that you pay a certain price for "an area" but you don't know how much Botox you got. It also means that the same amount of Botox is being placed in a 240 pound man as a 120 pound woman. In our Santa Rosa Botox practice the glabellar area is treated individually and the number of... more
