A few drops of Wrinkle Relaxers are injected with an extremely small needle into the muscle that creates a wrinkle. This blocks the nerve impulses from stimulating the muscle and as a result the muscle relaxes. As the muscle stops contracting, the skin overlying the muscle also relaxes. This results in the wrinkles/lines in the skin to soften.
Surrounding untreated facial muscles will contract in the normal fashion. This allows normal facial expressions to remain unaffected.
