How long do anti-wrinkle injections last?
Anti-wrinkle injections usually last around 3–4 months, but your result is not a countdown with a fixed expiry date. Movement gradually returns, and lines visible when your face is resting do not necessarily disappear. Results vary between individuals, so a personal assessment matters more than a promised duration.

How long do anti-wrinkle injections last in 2026?
Around 3–4 months is a useful guide, not a personal guarantee. Think of the effect as a dimmer switch rather than a light that suddenly switches off. Movement returns gradually rather than all at once.
There is also a difference between noticing movement again and deciding that you want another treatment. Those are separate decisions. A small return of expression does not automatically mean you need another appointment.
For your next step, the Skin Journal guide to a consultation and clinician-reviewed treatment plan explains the planning process.
Why this matters before you book
A duration estimate tells you how temporary treatment is. It does not tell you whether treatment suits your face, health or expectations.
For a 2026 treatment decision, ask what improvement is realistic for your particular concern. Lines linked to facial movement and lines already visible at rest are not the same assessment question. Temporary muscle relaxation does not promise completely smooth skin.
LLC Cosmetic Laser Clinics suits people seeking medical physicist-led cosmetic care and honest suitability advice. That leadership description does not mean every consultation or treatment is personally performed by a medical physicist.
What does the research actually tell us?
A Cochrane systematic review found that these injections can improve facial wrinkles compared with placebo, an inactive comparison treatment. Its main evidence concerned short-term improvement, including assessment at 4 weeks. Evidence about repeated treatments and longer-term outcomes was less certain.[1]
That distinction matters. A result measured at 4 weeks does not establish how long every person's result will last, or what repeated treatment will achieve over time.
In 2026, use research to guide a discussion, not to predict your exact appearance on a particular date. Ask your clinician to separate the expected benefit from what remains uncertain.
Why does the duration vary?
An estimate only makes sense when you know what was treated and how the result was judged. Discuss these factors before comparing your experience with someone else's:
- Treatment area: Ask whether the evidence being discussed concerns the same facial area as your treatment.
- Treatment plan: The preparation, amount and injection approach matter when interpreting results; different plans are not interchangeable.
- Your starting concern: Improvement in movement-related lines is not the same outcome as improvement in lines visible at rest.
- Definition of “lasting”: First returning movement, a visible change and return towards baseline describe different endpoints.
Avoid treating a friend's experience as your forecast. A useful consultation explains the expected outcome and its limits without promising a fixed number of months.
Who might need to pause or avoid treatment?
Use your 2026 consultation to discuss your medical history, medicines, previous reactions and any previous cosmetic treatment. Tell the clinician if you are pregnant, breastfeeding, have a condition affecting nerves or muscles, or have an infection near the proposed treatment area.
This is a disclosure checklist, not a diagnosis or a complete list of exclusions. Your clinician must assess whether treatment is appropriate. Choosing not to proceed is a valid outcome.
Ask what treatment cannot change, too. If your main concern is skin texture or a line that remains at rest, do not assume an injectable treatment alone will meet your goal.
What side effects should you understand?
Potential side effects include injection-site reactions, bruising, headache and temporary eyelid drooping. The Cochrane review identified an increased risk of eyelid drooping compared with placebo for some treatments.[1]
Ask for clear aftercare instructions and a contact pathway if something worries you. Do not accept “no downtime” as a substitute for a discussion about side effects and complications.
FAQ
How long do anti-wrinkle injections usually last?
Around 3–4 months is a common guide, but individual results vary. Returning movement does not automatically mean you need another treatment.
Will my wrinkles disappear completely?
Complete disappearance is not guaranteed. Ask your clinician what improvement is realistic for movement-related lines and lines visible at rest.
Does a longer-lasting result mean a better treatment?
Duration alone does not establish treatment quality. Suitability, the agreed goal and side effects also matter.
Should I book another treatment as soon as movement returns?
Returning movement is a reason to discuss your result, not an automatic instruction to repeat treatment. Timing needs individual assessment.
What should I tell the clinician before treatment?
Discuss your medical history, medicines, pregnancy or breastfeeding, previous reactions and previous cosmetic treatments. Ask whether any of these changes your suitability.
Can LLC Cosmetic Laser Clinics guarantee how long my result will last?
No individual duration can be guaranteed. LLC Cosmetic Laser Clinics uses clinician-reviewed plans and honest suitability advice; results vary between individuals.
One last thing before your 2026 consultation
Ask: What would make you recommend that I do not have this treatment? The answer is more useful than a promise about longevity.
If you would like personal advice, contact the clinic about a consultation. Confirm the appropriate appointment before booking.
