What Are the Differences Between Botox and Dysport?

Botox and Dysport are two leading treatments in the fight against facial wrinkles, each offering a path to smoother, more youthful skin. Despite their shared goals, these treatments are not interchangeable, marked by distinct differences that can influence treatment outcomes. Both are derived from botulinum toxin type A, and they work by temporarily paralyzing facial muscles and reducing the appearance of fine lines and wrinkles. However, their formulation, dosage requirements, and effects on various facial areas diverge, and choosing between them is more than a matter of brand preference.

What Are Botox and Dysport?

Botox and Dysport are treatments designed to address facial wrinkles and fine lines, utilizing a similar active ingredient: botulinum toxin type A. This substance is produced by the bacterium Clostridium botulinum and works by blocking nerve signals to muscles. When injected into specific facial areas, it temporarily paralyzes or weakens the targeted muscles. As a result, the overlying skin relaxes, leading to a reduction in the appearance of wrinkles and a smoother skin surface.

Botox, known scientifically as onabotulinumtoxinA, has a long history of use, both medically and cosmetically. It’s approved for various applications beyond cosmetic improvements, including treatments for chronic migraines, excessive sweating, and specific muscle disorders. Dysport, or abobotulinumtoxinA, shares a similar profile, having been used extensively in Europe before gaining approval in the United States for cosmetic applications.

The principle behind their use in cosmetics is grounded in neuromodulation—the temporary alteration of nerve activity. By precisely targeting facial muscles responsible for expressions that lead to wrinkles, such as frowning or squinting, these treatments can temporarily diminish the visibility of age lines. This makes Botox and Dysport popular choices for individuals looking to achieve a more youthful appearance without the need for invasive surgery.

Key Differences Between Botox and Dysport

Botox and Dysport, while similar in their use of botulinum toxin type A to address facial wrinkles, exhibit several key differences that influence their application and results. Understanding these distinctions is necessary for selecting the right treatment for individual cosmetic needs:

  • Dosage and Dilution: Dysport is generally dosed differently than Botox, with a higher volume required to achieve similar effects. This difference stems from the way each is diluted before use. Consequently, a direct comparison of unit numbers between the two does not translate to equivalent results.
  • Molecule Size: Dysport contains smaller molecule sizes than Botox. This characteristic enables Dysport to spread more easily over a larger area, which can be advantageous or less desirable depending on the treatment area’s size and desired precision.
  • Diffusion and Precision: Due to its smaller molecules, Dysport tends to diffuse more, covering a broader area with fewer injections. This makes it potentially more suitable for larger surface areas needing treatment. In contrast, Botox’s formulation offers more localized control, making it ideal for smaller, more defined areas.
  • Onset of Action: Patients might notice the effects of Dysport appearing slightly faster than those of Botox. Dysport can show results within 1-2 days, whereas Botox might take 3-5 days for the full effect to be visible.
  • Duration of Effect: Both treatments offer temporary results; however, Botox’s effects can last slightly longer. Typically, Botox results may persist for about 4-6 months, whereas Dysport’s outcomes might begin to diminish around 3-4 months after treatment.
  • Treatment Areas: Their differences in diffusion and molecule size make Dysport and Botox more suited for some facial regions. Dysport may be preferred for broader areas like the forehead due to its spreading capability, while Botox might be chosen for areas requiring precision, such as around the eyes or lips.

Pros and Cons

Both Botox and Dysport present viable options for treating wrinkles, with their respective advantages and limitations. The choice between them should consider the specific treatment goals, areas of concern, and personal preferences regarding onset time and maintenance schedule. 


Botox and Dysport

  • Effectiveness: Both treatments effectively reduce the appearance of facial wrinkles and fine lines, offering a smoother, more youthful complexion.
  • Minimally Invasive: As injectable treatments, they are non-surgical options that require no downtime, making them convenient choices for individuals seeking cosmetic improvements without the commitment of surgery.
  • Versatility: Apart from cosmetic applications, these treatments have medical uses, including managing conditions such as excessive sweating and chronic migraines.

Botox Specific

  • Precision: Botox’s formulation allows for targeted treatment of small areas, making it ideal for precisely addressing fine lines around the eyes and forehead.

Dysport Specific

  • Rapid Onset: Dysport may show results faster than Botox, often within a couple of days, making it a preferable option for those seeking quick improvements.
  • Spread: Due to its formulation, Dysport can cover a larger area with fewer injections, potentially making it more efficient for treating extensive areas like the forehead.


Botox and Dysport

  • Temporary Results: Both treatments offer temporary solutions, requiring periodic repeat injections to maintain results, which can be a commitment in time and expense.
  • Risk of Side Effects: Though generally safe, there’s a risk of side effects, including bruising at the injection site, headache, or, in rare cases, the spread of toxin effects to other body parts.
  • Cost: The cost can add up over time, especially since maintenance treatments are necessary to preserve the cosmetic effects.

Botox Specific

  • Delayed Results: The full effect of Botox might take longer to appear, usually several days post-injection, which may not suit those looking for immediate results.

Dysport Specific

  • Precision Limitations: Due to its propensity to spread, Dysport might not be the best option for treating smaller areas where more precise control is desired.
