Botox vs. Dysport: What’s the Difference?
If you’re considering a neurotoxin treatment for fine lines and wrinkles, you’ve probably heard of both Botox® Cosmetic and Dysport®. While both treatments temporarily reduce muscle activity that contributes to expression lines, there are differences between the two.
At Careen Aesthetics in Merced, California, neurotoxin treatments are customized based on your facial anatomy, muscle movement and aesthetic goals—with an emphasis on balanced, natural-looking results.
What Are Botox and Dysport?
Botox® Cosmetic and Dysport® are prescription botulinum toxin type A products. When injected into specific muscles, they temporarily reduce muscle activity that contributes to dynamic wrinkles—the lines that become more noticeable with facial expressions such as frowning, squinting or raising your eyebrows.
Common cosmetic treatment areas include frown lines between the eyebrows, forehead lines and crow’s feet. Treatment areas and dosing are individualized based on your facial anatomy and goals.
How Are Botox and Dysport Different?
Although Botox and Dysport work in similar ways, they are formulated and dosed differently. Their units are not interchangeable, so the number of Botox units used should not be directly compared with the number of Dysport units used.
Onset and individual response can also vary. Some patients begin noticing changes within several days, with results continuing to develop after treatment.
How Long Do Botox and Dysport Last?
Botox Cosmetic and Dysport results are temporary and vary from person to person. In general, results may last approximately 3–4 months, depending on the treatment area, individual metabolism, muscle activity and dose used.
With consistent treatments, some patients find they are able to maintain their desired results with regularly scheduled appointments.
What Areas Can Botox and Dysport Treat?
Botox Cosmetic and Dysport can be used to soften the appearance of expression lines in several areas of the face. Common treatment areas include frown lines between the eyebrows, forehead lines and crow’s feet around the eyes.
Treatment is customized based on your facial anatomy, muscle movement and aesthetic goals, with an emphasis on maintaining natural-looking facial expression.
Botox vs. Dysport: Which Is Right for You?
There isn’t one neurotoxin that is right for everyone. The choice between Botox Cosmetic and Dysport depends on factors such as the treatment area, your facial anatomy, muscle movement, previous treatment experience and your aesthetic goals.
During your consultation at Careen Aesthetics, we’ll discuss your goals and create an individualized treatment plan designed to provide balanced, natural-looking results.
