Dysport usually starts to show within 24 to 48 hours, most people notice a clear change by day two or three, and the full result develops over 7 to 14 days. At Skinsation LA in Los Angeles we judge the final result, and any touch-up, at the two-week mark. The reel embedded below is a client's own day-by-day record of the first four days, and it shows the part most people are not told: Dysport does not switch on, it eases in. Here is what the first two weeks look like, why the timing varies from person to person, and when a touch-up is actually decided.
When does Dysport start working?
Not on the day it is injected. Dysport is abobotulinumtoxinA, a botulinum toxin type A in the same family as Botox, and it works by temporarily blocking the signal from a nerve to a targeted muscle so the muscle relaxes and the line that repeated movement creates softens. That signal does not stop at the moment of injection. In our office the first softening is usually visible within 24 to 48 hours, most clients notice a clear change by day two or three, and the full effect is in by day 7 to 14. The Dysport appointment itself takes 15 to 30 minutes; the result takes two weeks to finish arriving.
- Day 0: nothing visible yet. Small injection points, a cold compress, and a short list of what not to do for the next 4 hours.
- Days 1 to 2: the first softening. Expressions still work; the change is subtle.
- Days 2 to 3: a clear change for most people. The frown and brow-raise no longer pull the way they did.
- Days 5 to 7: noticeable improvement for most people.
- Day 14: the full result. This is when the face is assessed and any touch-up is decided.
What does Dysport kicking in look like day by day?
The reel below is one of our clients filming her own face on each of the first four days after a Dysport treatment, labeled day by day, running the same three expressions each time: raising the brows, frowning, and puckering. On day one the brows lift fully and the forehead creases the way an untreated forehead does. By day two the movement is already a little softer, and by day four the brow-raise and the frown are visibly smaller than on day one without the face looking frozen. The point of the reel is the gradient: there is no single morning when Dysport "kicks in". As our post says, "Everyone responds differently, and while some patients notice changes within a few days, full results typically develop around two weeks."
There is no single morning when Dysport kicks in. It eases in over the first week, and the result is judged at two weeks.
One client's four days are one client's four days. Individual results vary, and the same treatment on a stronger muscle, or a larger area, can run a day or two behind the reel.
Why does Dysport kick in faster for some people than others?
Because the muscle being treated is different in every face. At Skinsation LA your injector maps the muscles creating your dynamic lines and doses Dysport for your muscle strength, not for a fixed number of units, and a strong frown or a heavily used forehead takes longer to quiet than a light one. Dysport units are also not interchangeable with Botox units, so a Dysport dose always looks larger on paper; that is the unit system, not a heavier treatment. Our featured injector, Farah Chahine, PA-C, MMS, puts it this way: "Every unit is placed with a plan for how your face actually moves." That plan is why two people treated on the same afternoon can be on slightly different schedules the following week, and why we do not promise a date.
Onset windows here are what we see in our office and are not a guarantee. How quickly Dysport takes effect depends on the muscle treated, the dose placed in it, and your own anatomy, and is discussed at an in-person consultation. — Dr. Lusanik Galustian, MD
Is Dysport faster than Botox?
Often, yes, and that is one of the reasons we reach for it. In our experience Dysport begins to soften lines in about 2 to 3 days and Botox in 3 to 5 days, with both reaching full effect by about two weeks and both lasting 3 to 4 months. Dysport also diffuses a little more widely than Botox, which is why injectors often favor it for a broad area such as the forehead, while Botox stays more localized and suits precise areas such as crow's feet and the lips. Same family, different spread profile, and not every face gets the same answer. Our Botox vs Dysport comparison sets the two side by side on onset, spread, units, and cost; the per-unit price for Dysport lives on the service page and is sourced from our booking system, not from this article.
When is a Dysport touch-up decided?
At two weeks, not at day four. Because the result keeps developing until about day 14, adding units in the first week means treating a result that has not finished arriving. The face is assessed once the full effect has developed, and a small touch-up is recommended then if a muscle is still moving more than planned. Our own post makes the same point: "Depending on your muscle movement, anatomy, and desired results, small touch-ups may sometimes be recommended after the full effects have developed." If a treated area is still moving fully at day 14, or one side has settled and the other has not, contact us for a follow-up; significant facial asymmetry that persists beyond day 14 is one of the specific reasons to call.
What should you do in the first 24 hours?
The first-day rules are the ones we give for every neuromodulator we inject. For the first 4 hours, stay upright and do not lie down or bend over, and do not touch, rub, or massage the treated area. Gently exercising the treated muscles, frowning and raising the eyebrows, is encouraged. Skip vigorous exercise and alcohol for the first 24 hours. None of this speeds Dysport up; it keeps the product where it was placed while it takes hold. Our neurotoxin aftercare page has the full first-24-hours list, the days 2 to 14 timeline, and the specific clinical reasons to call us right away, including a drooping eyelid that lasts longer than 7 days.
How long does Dysport last?
Dysport typically lasts 3 to 4 months, the same as Botox. Most clients return every 3 to 4 months to keep the result continuous, and the interval is set by how your muscles respond rather than by a fixed calendar; how often to come back depends on the area, the dose, and how long you have been treating it.
Our office is on San Vicente Boulevard in Carthay Circle, and we see Dysport clients from across Los Angeles, Beverly Hills, and West Hollywood.
- Dysport starts to show in 24 to 48 hours, most people see a clear change by day 2 to 3, and the full result is in by day 7 to 14.
- It eases in rather than switching on; a muscle still moving on day three or four is normal.
- Timing varies with the muscle treated, the dose placed in it, and your anatomy; Dysport units are not Botox units.
- Dysport is often faster than Botox (about 2 to 3 days vs 3 to 5) and spreads a little wider; both last 3 to 4 months.
- Touch-ups are decided at the two-week assessment, never in the first week; stay upright and hands-off for 4 hours, no hard exercise or alcohol for 24.
This article is general education, not medical advice, and individual results vary. Whether Dysport suits you, how many units your muscles need, and when a touch-up is appropriate are decided at an in-person assessment. — Dr. Lusanik Galustian, MD
