How Long Does Dysport Last for Wrinkles on the Forehead?

Is it possible to have back to back Dysport procedures on the face?

Dysport can last up to 4 months. This will vary from person to person. You should not be treated more than every 90 days. Our Biospa offers free consultations.

Dysport for wrinkles

Most patients see improvement within several days of injection with Dysport. The result will usually last about three to four months at which point the muscle action gradually returns and the lines and wrinkles begin to reappear. Over time, however, and with repeated injections, the lines and wrinkles will become less severe as the muscles are trained to relax.

Dysport for forehead lines

Dysport has the same active ingredient as Botox for treating lines in the forehead.  The onset of action seems to be a day or two faster for Dysport in some individuals and, anecdotally, it may last longer for some patients in the forehead and around the eyes.  Studies show that Dysport may work better in the forehead than Botox though they both should last 10-16 weeks on average.

How Long Does Dysport Last at Forehead

Dysport normally lasts around 3-4 months. The maximum effects of Dysport are usually seen at about 2 weeks, so if a touch up is required, you can generally treat the same area again at that time. If you are treating a different area, then you may do that at the same time or on a different day without having to wait 2 weeks.

Frequency and Duration of Dysport



Like Botox Cosmetic, Dysport typically lasts between 3-4 months, depending on the person and the amount of Dysport injected.  It is safe to schedule subsequent Dysport injections back to back in other areas on the face, such as glabellar lines, crowsfeet, lines running alongside of nose, and wrinkles above the lip.  If your doctor went too conservative on your forehead and you do not see a result within 2 weeks, I recommend scheduling a follow up appointment for a touch up.  I hope this helps!

Effects of Dysport on Wrinkles

Thank you for your question. Dysport can last an average of 3-4 months depending on an individual's metabolism. You may return for another injection before it has completely metabolized, around 2-3 months. You may have Dysport performed on other areas such as between your brows (glabella), crow's feet, bunny lines, etc. Be certain to be under the supervision of a board certified dermatologist or plastic surgeon with expertise in injectables for the safest and most effective treatments. I hope this helps.


Both Dysport and Botox last approximately 3-4 months.  It is fine to have Dysport back to back once you feel like the effects are wearing off.

How Long Does Dysport Last?

Using 1 injection between and over the eyebrows, Dysport blocks the signal from the nerve to the muscles, ultimately resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles that cause frown lines. You should not be treated with Dysport more frequently than every 90 days.

How Long Dysport lasts for wrinkles on the forehead.

Dysport lasts approximately as long as Botox which is about 3-4 months. Other sources report that Dysport lasts between 4-6 months on average.

It is perfectly acceptable to have Dysport procedures back to back if you do not want to experience an intermittent time interval where the effects have worn off.  Some patients prefer to let the Dysport injection completely wear off before receiving their next treatment. However this is a matter of personal choice.

Dysport and Botox: duration of effect

Thanks for the question. There are five areas I commonly treat with Dysport and Botox:

1) horizontal forehead wrinkles

2) vertical wrinkles between the eyebrows

3) crow's feet

4) platysmal bands (neck bands)

5) masseter (bite) muscles: to reduce teeth grinding (bruxism) or shrink the jawline in patients with large, square jaws.

The effects of these neuromodulators usually last between 3 and 4 months though many of my patients have been able to break the habit of continually making these expressions or movements and are able to stretch out their treatment sessions to 6 to 9 months apart. This is particularly true of my teeth grinding patients, who usually come in once or twice a year.

As for your questions about retreatment, if you have received an adequate, properly placed dose, I would wait at least 3 months before being retreated in the same area. However, if you feel your wrinkles have not responded as you would like, you may be a candidate for a touchup of a few extra units. I usually advise my patients to wait 7-10 days for the effect and return for a complimentary touchup if they have not fully responded. If you are interested in having a different area treated, you can do this at any time. 

Best regards,
