Wrinkles are caused by repeated movements and muscle contractions, which means they can even develop in younger adults. Dysport temporarily prevent muscle contractions that cause frown lines, leaving the rest of your face to move naturally. In other words, no frozen look, just natural-looking results for any age adult. In just one 10-20 minute treatment, Dysport* may help improve the look of your frown lines for up to 4 months.
