Dysport treats moderate to severe frown lines between the eyebrows by reducing specific muscle activity. One injection into each of 5 points between and above the eyebrows temporarily prevents muscle contractions that cause frown lines, leaving the rest of your face to move naturally. It may help improve the look of your frown lines between the eyebrows for up to 4 months. The majority of patients see improvement in just 2–3 days after treatment.
