Wrinkles around the Eyes: wrinkles that develop around the edges of the eyes resembling Crow’s Feet. Depending upon the severity of the wrinkles, these lines may not be noticeable while relaxed but show up most while laughing or smiling. If left untreated, these wrinkles will become more noticeable even while relaxed. On average, people will need 6-12 units of Botox in this area. Dysport tends to be better in this region as it gives you more relaxed and natural look. With Dysport, you will need about 20-30 ($60-$90) units per eye to achieve results. Cost of Dysport and Botox are about the same despite needing more units of Dysport.
