How it works:
Cosmetic injections work to block the release of neurotransmitters; therefore the muscle doesn’t receive the message to contract. This leads to weakening of the muscle contraction and temporary paralyses the muscle.
Who it is suitable for:
Common sites are the ‘frown lines’ in the glabella (the area between the eyebrows), ‘crow’s feet’ at the outer aspects of the eyes, and horizontal lines and creases on the forehead due to the action of the frontalis muscle which raises the eyebows. In many patients this muscle is unconsciously overused to elevate drooping skin in the upper eyelids ( blepharochalasis ). In addition to the forehead wrinkles this can produce ‘tension headaches’. Muscle relaxing injections in the forehead can thus not only eliminate the wrinkles but also relieve the headaches. Similarly upper blepharoplasties can help the forehead muscles to relax, as there is no longer any excess skin. Cosmetic injections can be also used for “hyperhidrosis” or excessive sweating.
How many treatments are needed?
Following injection into targeted areas, the underlying muscles cease to contract for approximately 3 to 4 months.
