How Long Does Dysport Last?
A realistic look at how long Dysport lasts, what affects it and when to schedule your touch-up.
The short answer
Dysport and Botox are both FDA-approved botulinum toxin injectables, and both temporarily relax the muscles that cause expression lines. The differences are subtle: Dysport often starts working a little sooner and tends to spread slightly more, while Botox is more concentrated and stays a bit more localized.
Key takeaway
Neither is "better." Dysport is a great fit if you want faster results or are treating a broader area like the forehead. The most important factor is an experienced injector who plans your dose specifically for the product used.
How Dysport works
Dysport blocks the signal between nerves and the targeted facial muscles, so they relax and the skin above them smooths out. Many patients notice softer lines in 2 to 3 days, with most seeing results between 3 and 7 days.
- Fast-acting onset compared with other neurotoxins
- Treats frown lines, forehead lines and crow's feet
- Natural-looking results lasting about 3 to 4 months
How Botox works
Botox uses the same basic mechanism, relaxing targeted muscles to soften lines. Results usually appear in 3 to 5 days and peak around two weeks, and the product tends to stay close to where it is placed.
Same goal, slightly different personality. Your injector chooses the product that suits your face and your timeline.
Both products are well studied and safe in trained hands. Units are not interchangeable between brands, which is why dosing should always be planned for the specific product.
Side-by-side comparison
| Comparison | Dysport | Botox |
|---|---|---|
| How it works | Relaxes targeted facial muscles | Relaxes targeted facial muscles |
| Typical onset | Often 2 to 3 days, most by 3 to 7 days | Usually 3 to 5 days |
| Spread | Slightly wider, suits larger areas | More localized |
| Longevity | About 3 to 4 months | About 3 to 4 months |
| Downtime | None | None |
Who should choose what
If you want quicker results before an event, or you are treating a larger area such as the forehead, Dysport is a popular choice. If you are treating a small, precise area, or you already know Botox works well for you, there is no need to switch.
Neither treatment suits everyone. Pregnancy, breastfeeding, active skin infections at the injection site and certain neuromuscular conditions are common reasons to wait. Dysport also contains a trace of cow's milk protein, so a milk allergy is a reason to avoid it. A consultation will confirm what is right for you.
What to expect
- Consult and assess. Your injector reviews your goals and history, and studies how your face moves.
- Treatment mapping. Injection points and doses are marked and agreed with you before anything begins.
- Injection. Tiny, precise injections take about 10 minutes, with no recovery period.
- Results. Lines soften over 3 to 7 days and settle by about two weeks.
