Dysport® treats deep lines and wrinkles by immobilizing muscles, similar to Botox. Developed in the United Kingdom in the early ’90s, Dysport® has been used overseas for many years. Dysport® was approved by the Federal Drug Administration in April 2009 for the treatment of head and neck muscle spasms and deep lines between the eyebrows.
Dysport® is a formulation that has been shown to deliver temporary improvement in moderate to severe frown lines, even with repeat treatments. So, the effect of repeat treatment with Dysport may be comparable to your first use.
