Any other cosmetic use is not approved and becomes the responsibility of the treating doctor. It is not uncommon for medication to be used to treat conditions for which they have not been approved. However, the implications of this should be explained to the person at the time of prescription.
Botulinum toxin type A is injected into certain muscles of the face to soften facial lines, including:
- frown lines between the eyebrows
- lines across the bridge of the nose
- ‘crow’s feet’ wrinkles extending from the outside corners of the eyes
- forehead lines
- lines on the throat (‘turkey neck’)
A very fine needle is used to inject the botulinum toxin type A into selected facial muscles. Discomfort is minimal and brief. Most people describe it as an ant-bite sting for a few seconds. The wrinkle-smoothing effects of the injection may last for up to six months.
