Botox and Dysport are both injectable neuromodulators that work by relaxing the muscles that cause wrinkles. They contain similar active ingredients, but there are some differences between them that may affect their efficacy, onset of action, and duration of effect. One of the main differences between Botox and Dysport is in their molecular structure. Dysport has smaller-sized molecules compared to Botox, which may allow it to spread more easily and affect a wider area of muscles. As a result, some studies suggest that Dysport may take effect more quickly and may last longer than Botox in some cases. However, the dosage of Dysport needed to achieve the desired effect is typically higher than that of Botox. In general, the recommended conversion ratio is 2.5 to 3 units of Dysport for every 1 unit of Botox. This means that you may need more units of Dysport than Botox to achieve the same level of muscle relaxation. It is important to note that the appropriate dosage and injection technique for Botox and Dysport can vary depending on a variety of factors, including the area being treated, the severity of the wrinkles, and individual patient factors. Therefore, it is essential to consult with a qualified healthcare provider who is experienced in administering both Botox and Dysport to determine the appropriate treatment plan for you.
