Botox® cosmetic and Dysport® are approved for the temporary reduction in the appearance of moderate to severe wrinkles involving the glabellar region (frown lines between the eyebrows) and lateral canthal lines (crow's feet). The upper / mid forehead is also commonly treated with great results in reduction of horizontal lines. These wrinkles are due to over activity of the underlying muscles of the face. Botox® works by decreasing the function of the muscle underlying the wrinkles, thus giving a smoother look to the skin above.
New studies have also shown that early use of either product can decrease the formation of wrinkles, and lead to a later onset of wrinkle formation in patients who do not yet have significant wrinkle formation. Prevention always works better than treatment.
Most patients will require 24 units for crow's feet, 20 units for glabellar lines (frown lines between the eyebrows), and 24 units for the mid / upper forehead. This gives a natural and youthful look, not like the "frozen face" that was associated with early Botox® and Dysport® use. Each patient's treatment plan will be tailored to them. The muscles of the face work in balance, thus it is recommended all three areas be treated to get a balanced look.
