How Long Does Dysport Last?
What to expect — from first effect to when it fades — and what influences the timeline.
Dysport typically lasts about three to four months, with effects often appearing within two to four days and reaching their peak around two weeks. As with any neuromodulator, that timeline is a typical range, not a guarantee — several individual factors shift it in either direction.
Understanding what drives longevity helps set realistic expectations and build a sensible treatment rhythm, rather than chasing a result that never fully wears off. For the full treatment overview, see Botox & Dysport.
Set Expectations
It’s temporary by design — that’s a feature, not a flaw.
By The Numbers
The Typical Timeline
Onset within days, peak around two weeks, and a return of movement over a few months. Here’s what shapes it.

Onset in days · peak ~2 weeks · effect ~3–4 months
What affects how long it lasts
- Dose and the area treated
- Your individual metabolism
- Muscle strength and activity
- How expressive the area is
- Consistency of past treatments
Getting the most from it
- Appropriate (not minimal) dosing
- A consistent treatment schedule
- Realistic expectations — it’s temporary by design
- Good skincare and sun protection
- Avoiding the urge to ‘chase’ perfection
Typical ranges; individual onset and duration vary. Timeline reflects common clinical experience, not a guarantee.
The DetailsWhat Changes the Timeline
Why your experience may differ from the average:
Dose & Area
Larger, stronger muscles and higher doses can affect how long results hold.
Metabolism
Individual metabolism influences how quickly the effect fades.
Muscle Activity
Very active or expressive muscles may regain movement sooner.
Consistency
Regular, well-timed treatment can make results feel more sustained over time.
First-Timers
Your first treatment is a baseline; the rhythm is refined from there.
Lifestyle
General factors like stress and activity level can play a minor role.
PlanningBuilding a Sensible Rhythm
Rather than re-treating the moment any movement returns, we establish a schedule that keeps results looking natural and consistent — typically revisiting every few months as the effect fades.
Dysport vs. Botox longevity
Duration is broadly similar between the two; see Botox vs. Dysport for how they otherwise differ.

Our Approach
The aim is consistent and natural — not a result that never moves.
How We DecideEvidence-Based Practice
Aesthetic medicine changes rapidly, and novelty alone is not evidence. At Onassis Skin Health, treatment and skincare protocols are developed with reference to peer-reviewed medical literature and respected clinical guidance — then interpreted for the individual in front of us.
Research does not replace clinical judgment. It informs it.
Published evidence is read in the context of your anatomy, skin type, medical history, risk profile, lifestyle and desired outcome. Product and technique selection, dosing or placement, and pre- and post-care all follow from that combination of evidence and individualized assessment — not from what is simply popular or available for purchase.
When AppropriateMaking It Last Well
Longevity is supported by sensible dosing and overall skin health:
+ The Right Tool
We match the product to what’s actually driving your concern — movement, volume or skin quality — rather than defaulting to one injectable.
+ Medical Skincare
Healthy, well-cared-for skin makes any injectable result look better and last better.
+ Restraint
Often the best plan uses less than expected — or builds gradually and reassesses.
Combinations are recommended only when each element contributes meaningfully to your goals. Sometimes the right plan is a single, well-chosen treatment — and sometimes it is choosing not to treat at all.
Good to KnowYour Timeline, Specifically
Your personal onset and duration are best understood over your first couple of treatments, as we learn how your muscles respond. We’ll set a realistic schedule rather than promising a fixed number of months — because the honest range is about three to four.
