“Like Kleenex and Band-Aid, Botox is a brand name that’s become indistinguishable from the product. But in a new randomized study, Botox’s newer competitor, Dysport, appeared to have the edge in smoothing wrinkles. Botox (onabotulinumtoxinA) was approved by the Food and Drug Administration (FDA) to treat frown lines — those pesky wrinkles between the eyebrows — in 2002. In 2009, a competitor, Dysport (abobotulinumtoxinA) was approved for the same use.
Both drugs have also been approved for other cosmetic and medical uses, and doctors administer them widely to smooth wrinkles even in areas they haven’t been specifically approved to treat, namely around the outer corner of the eyes.
