Consent for Use of BOTOX® and DYSPORT®
Botox® or Dysport® are purified proteins that can be injected into a muscle to cause temporary weakness or paralysis of that muscle. Botox® and Dysport® are indicated for the temporary improvement in the appearance of moderate to severe expression wrinkles. The results appear in 2-14 days, depending on the individual, and usually last about 3-4 months, but can be shorter or longer.
Botox® and Dysport® block neuromuscular transmission by binding to receptor sites on motor nerve terminals. This blocks the release of acetylcholine and renders the muscle unable to contract. Frown lines (vertical lines between the eyebrows) are due to contraction of small muscles in this area. The FDA has approved the use of Botox® and Dysport® to improve these lines/wrinkles between the eyebrows and the wrinkles next to the eyes (Crow's feet). Botox® and Dysport® have NOT been FDA approved for treating or the horizontal lines/wrinkles on the forehead, "bunny nose", dimpled chin, vertical lines around the lips, neck bands, horizontal neck lines, lip augmentation, or "square jaw". However, these areas, in addition to other areas of the face and neck, have been successfully treated with Botox® and Dysport® for many years.
It is important to understand that wrinkles/lines visible at rest (relaxation of the facial muscles), may not improve with the administration of Botox® or Dysport®. Lines/wrinkles visible at rest are more likely to respond to the injection of fillers in those areas.
