Over time, repeated movement of the facial skin by muscle forms frown lines between the eyebrows. Wrinkles are not only age related. Frown lines are “dynamic”—they happen because of the way a person’s face moves. Because frown lines are created by facial movements such as frowning or squinting, they may develop even in younger adults. Dysport is used to treat moderate to severe frown lines in adult patients by blocking the nerve signal that causes muscles above and between the eyebrows to contract. Dysport has little to no downtime after injection, and repeated procedures have been shown to be as effective as your very first.
