Just very recently, the Food and Drug Administration approved Dysport, the first new botulinum toxin for wrinkles and muscle spasticity since cosmetic Botox was introduced in 2002. This latest wrinkle fighter is a modified version of botulinum toxin A and inhibits facial muscle contractions that over time lead to forehead lines, frown lines and crows feet. Dr Orloff  found that Dysport was extremely effective in reducing frown lines between the eyebrows. Our results in treating patients showed that Dysport injections would reduce lines and furrows between the eyebrows within 7 days. Side effects were infrequent and resolved within a few weeks.
