Muscle relaxants prevent muscle movements which cause dynamic wrinkles.
Muscle relaxants are toxins derived from a bacterium. The toxin blocks impulses from the nerves to the tiny facial muscles that are responsible for the deep muscle pull creases. Consequently, the muscles relax so that the undesirable creases gradually fade away. After treatment, the overlying skin remains smooth and unwrinkled while the untreated facial muscles contract in a normal fashion, allowing desirable facial expression to be unaffected.
Three muscle relaxants have been approved in Canada for the treatment of glabellar folds – those vertical wrinkles that appear between the eyebrows. The most commonly recognized muscle relaxant is BOTOX COSMETIC®. It has been used by physicians for medical and aesthetic purposes for a number of years. More recent products available to Canadian physicians include DYSPORT™ and XEOMIN®.
These same products have been approved for the treatment of excessive sweating (hyperhydrosis).
Description: Injection of muscle relaxants into facial muscles inhibits muscle action; thereby decreasing dynamic wrinkles. Muscle relaxants are injected into the underarms to control excessive sweating.
Average Cost: Muscle relaxant injections for treatment of dynamic wrinkles cost $230.00 per syringe.
Length of Procedure: Minutes.
Anesthesia: Not required.
Recovery Time: Immediate; results seen within 3 to 10 days.
Treatment Frequency: On average two to four times a year depending on how quickly the muscle relaxant metabolizes.
Risks: Bruising, numbness and burning during injections. Eyelid droop is possible, but rare and temporary.
Duration of Results: Temporary.
