I have had frown lines treated with 40 units and had good and long-lasting results. Even 8 months later, it had not fully worn off. I went to another doctor and asked him to treat my frown lines, but it appears he injected my whole forehead. I can still frown, but can't lift my brows at all. I was told he used 75 units. It's really awful and now I'm afraid the higher dose means it will take even longer to wear off. When can I expect to at least start getting movement back?

The more Dysport given, the longer it could last

The dose of the neurotoxin is related to how long it lasts. In general, the more Dysport given, the longer it could last. But, we always want to achieve the ideal aesthetic result which is usually to soften the lines and reshape the face, rather than just freeze it. If the forehead is very frozen and the furrows were not treated significantly, sometimes treating the furrows as a touch up may help to make the forehead appear less frozen and the brows less droopy.

Dysport Effect lasts for up to 6 months, sometimes longer.

The overall effect of Dysport could last for 6 months, and at times longer, based on my experience. However, a lot of the sensation you are currently feeling of not being able to raise your eyebrows (which tends to be more pronounced during your first injection of this area) should wear off in the next few weeks. You will soon regain some additional movement of the eyebrows, and will probably be very happy to enjoy the next several months free of forehead lines. Be patient. I think you will... more

Does Dosing Effect Duration of Dysport?

Very good quesion, but it is not clear why your forehead was dosed if you wanted the frown lines (glabella area) dosed. Lines that are horizontal are a result of forehead movement. Lines that are vertical between the brows are a different muscle group than the forehead. With that said, make certain that the practitioner understood your treatment goals. In our experience and that of studies, dosing does have a direct correlation on duration. Underdosing not only... more

Duration of Action of Dysport

The length of action of Botox and Dysport are not dependent on the dose. The dose only affects the effect. However the duration of effect will be the same regardless of dose. So, the Dysport should last about as long as it did the first time you had it injected.

If I use more units of Dysport will it last longer?

In order to achieve a maximal benefit with Dysport for the treatment of a specific muscle, one must use the correct number of units to achieve that maximal result. If you use more units than that, there would be no appreciable difference--it would likely not last longer. If one was below the maximal benefit, then using more units would increase the effect (better paralyze the muscle) and/or it would last longer. Lets think of a see saw at a playground. If a boy... more

Don't worry will wear off

Don't worry, your Dysport will probably last no longer than it did last time. I do find that sometimes a little more , injected IN THE SAME AREA, does last a bit longer but yours was spread further out which does not effect longevity. Maybe will last an even shorter time.

How Long to Expect Dysport to Last

The effects from Dysport or Botox injections will typically last from three to six months and will rarely last much longer. I typically inject fifty units of Dysport when treating the glabellar forehead. It is not likely the higher dose will make the effect last longer, especially since it was spread out over a larger area.

Duration of Action of Botulinum Toxin type A

Dysport, like Botox Cosmetic, are both serotype A botulinum toxins, and both have a similar duration of action – typically 3-6 months with an average of about 4 months. Many patients who have been treated with both products say that the Dysport works a few days sooner then the Botox; but I have not seen any difference in the overall duration of action. The recommended dose of Dysport for the treatment of glabellar frown lines is 50 units, the dose used in the FDA trials. This dose... more

Dysport

You had a good result with the first doctor. Why did you go to another doctor the second time????? Treating the frown lines does not include injecting the entire forehead??????????????? The forehead is for the tansverse lines on the forehead. and the forehead muscle need much less neurotoxin, it is a very sensitive muscle and complte paralysis of the forehead muscle ( FRONTALIS) will result in brow drooping. No antidote, effect will last 4-6 months

Length of Dysport Effects

The recommended dosage of Dysport for glabellar (frown) lines is 50 units, which typically last four to four and a half months. Younger people can get longer results. You don't list your age or how long after your treatment you noticed your results. The forehead is an off label use of Dysport, but 75 units is not an unreasonable amount. With this amount of Dysport,over your entire forehead you should expect similar duration as you had in your frown lines. If you had injections... more
