Dysport vs. Botox: What’s the Difference?
If you’re considering injectable treatments to smooth out fine lines and treat facial wrinkles, you’ve probably come across two popular options: Botox and Dysport. Both botulinum toxin products are widely used to reduce the appearance of facial wrinkles and belong to a category of treatments known as neurotoxins. While they work in similar ways by temporarily relaxing specific facial muscles, there are a few key differences that may influence which one is the right choice for you.
Let’s explore the ins and outs of each treatment so you can make an informed decision with confidence.
Botox 101
Botox, also known by its scientific name onabotulinumtoxinA, has been a trusted cosmetic treatment for decades. It’s FDA-approved to treat glabellar lines, AKA frown lines, which are the vertical lines between the eyebrows, as well as forehead lines and crow’s feet. Beyond aesthetics, Botox injections are also used to address several medical concerns. It has been approved for the treatment of chronic migraines, excessive sweating of the underarms (also known as hyperhidrosis), overactive bladder, and even certain types of muscle spasms and stiffness.
The way Botox works is simple yet effective. It temporarily blocks the nerve signals to the muscles in the treated area, which softens their movement and smooths out the overlying skin. This gives the face a more relaxed and youthful appearance without altering your natural expressions.
Dysport 101
Dysport, or abobotulinumtoxinA, is a newer option compared to Botox but functions in much the same way. It is FDA-approved to treat moderate to severe glabellar lines and is quickly gaining popularity for its fast-acting results and subtle finish. Like Botox, Dysport works by relaxing the muscles that cause dynamic wrinkles—the ones that form due to repeated facial movements like frowning, squinting, or raising your eyebrows.
Although similar in purpose, the formulation of Dysport is slightly different from Botox, which can influence how it spreads under the skin. This makes it especially useful for treating larger areas of the face or areas where a softer, more diffused result is desired.
How Botox and Dysport Differ
While very similar, Dysport and Botox injections do have some distinct differences, including where they are often injected, their level of concentration, and the side effects they can produce.
Where It’s Injected
Despite their shared purpose and similar ingredients, Botox and Dysport are not exactly the same. One of the key differences lies in how they spread once injected. Dysport tends to diffuse more readily beneath the skin, making it a great choice for treating broader areas such as the forehead. On the other hand, Botox stays more localized, which allows for greater precision, ideal when targeting smaller areas or when a more controlled effect is needed. In some cases, providers may even use both Botox and Dysport in different areas of the face during the same treatment session to take advantage of each product’s strengths.
Dosing
Another notable difference is in how the two treatments are dosed. Dysport and Botox units are not equivalent, meaning that a higher number of Dysport units is often required to achieve the same result as a smaller number of Botox units. However, this doesn’t necessarily make Dysport more expensive or less effective; it’s simply due to how the medications are formulated. A skilled provider will understand the appropriate dosage conversions to ensure safe and effective results.
Onset of Effects
When it comes to timing, Dysport is often reported to take effect more quickly than Botox. Many patients begin to see improvement within two to three days of receiving Dysport injections, whereas Botox may take about five to seven days for results to fully develop. That said, both treatments typically last about three to four months, although the exact duration can vary depending on factors such as the treated area, your metabolism, muscle activity, and the specific dosage used. With consistent treatment over time, you may even notice that your Dysport or Botox results last longer between sessions.
Side Effects
Side effects for both Botox and Dysport are generally mild and temporary. The most common ones include slight swelling or redness at the injection site, bruising, headaches, and occasionally, a sensation of heaviness or temporary drooping in the treated area. In some cases, people may experience dry or watery eyes, but these symptoms usually resolve on their own within a few days.
