How Long Does Dysport Last?

Quick Answer: For FDA-approved treatment of moderate-to-severe frown lines between the eyebrows, Dysport results may last up to five months. However, five months is a possible maximum rather than a guarantee, and many patients notice muscle movement gradually returning sooner. Duration depends on the treatment area, dose, injection placement, muscle activity, and individual response.

How Long Do Dysport Results Usually Last?

Dysport provides temporary improvement in frown lines caused by repeated muscle movement. The manufacturer reports that some patients continued to show improvement for up to five months after treatment of moderate-to-severe glabellar lines between the eyebrows.

Not every patient will experience the full five-month duration. Results often begin fading before that point, and the effect usually wears off gradually rather than disappearing overnight.

As Dysport fades, the treated muscles begin moving more freely and expression lines slowly become noticeable again. The area generally moves back toward its pretreatment appearance.

When Does Dysport Start Working?

Some patients may notice early changes within 24 hours, although results more commonly begin appearing within two to three days. The full effect may continue developing after the first few days.

Do not judge the result immediately after treatment. If the area appears uneven or different from what you expected, contact the treating provider before assuming another injection is needed.

What Affects How Long Dysport Lasts?

The duration of Dysport may vary based on:

  • The treatment area
  • The dose administered
  • Injection placement
  • The strength and activity of the treated muscles
  • Previous response to neuromodulator treatments
  • Individual response

The manufacturer’s five-month claim is based on treatment of frown lines between the eyebrows. It should not automatically be applied to every off-label treatment area because muscle strength, movement, dosing, and treatment goals can differ.

How Can You Tell Dysport Is Wearing Off?

Dysport usually fades in stages. You may first notice more movement in the treated muscles before the lines fully return.

Other signs may include:

  • Frown lines becoming more visible during expression
  • The area taking longer to smooth after movement
  • The treated muscles feeling less restricted
  • The appearance gradually moving closer to its pretreatment state

Movement returning does not necessarily mean all improvement is gone. Some softening may remain while the muscles become more active.

When Should You Schedule Another Dysport Treatment?

Consider contacting the treating provider when muscle movement and expression lines begin returning. The provider can assess whether another treatment is appropriate and recommend a maintenance schedule based on your previous response.

Do not schedule injections more frequently simply to prevent all movement from returning. Treatment timing should account for the area treated, dose, health history, aesthetic goals, and how the previous session wore off.

Dysport units are specific to Dysport and cannot be directly compared with units used for Botox or other botulinum toxin products.

Can You Make Dysport Last Longer?

There is no skincare product, supplement, exercise, or home method proven to guarantee longer Dysport results.

Follow the aftercare instructions provided by the treating professional and avoid unnecessary pressure on the treated area immediately after the appointment. A consistent treatment plan may make the timing of results feel more predictable, but each session can still wear off differently.

Sunscreen and a suitable skincare routine may support the overall appearance of the skin, but they do not extend Dysport’s muscle-relaxing effect.

Are Dysport Results Permanent?

No. Dysport results remain temporary, even after repeated treatments.

When the effect wears off, muscle activity returns and the treated lines may gradually reappear. Stopping Dysport does not normally make the area permanently worse than it was before treatment.

Important Dysport Safety Information

Dysport is a prescription botulinum toxin product and is not appropriate for everyone. Discuss your health history, medications, previous botulinum toxin treatments, and any swallowing, breathing, or neuromuscular conditions with the provider before treatment.

Seek prompt medical care if you develop trouble swallowing, speaking, or breathing, unusual muscle weakness, or vision changes after treatment.
