60 units of Dysport by Dr. Daniel Fowler from Knoxville Center for Dermatology and Plastic Surgery. Dysport delivers the natural looking results using a prescription injection proven to help smooth the appearance of moderate to severe frown lines between the eyebrows without changing the look or movement of the rest of your face. Untreated muscles still work normally, so you can continue to express feelings naturally. It's the lines that are minimized, not your expressions. Expires 5/1/2020.
