Technically, Botox is onabotulinumtoxinA, while Dysport is abobotulinumtoxinA; according to dermatologist Shlipi Khetarpal, this means that the two “have the same primary active ingredient, but a different protein allows Dysport to [...] spread more.” Dysport is also only meant to treat your forehead and between your eyebrows, while Botox
can treat other areas.
