Used safely for decades to treat eye “twitches” and migraines even in small children, wrinkle relaxers (aka neurotoxins) effectively and safely treat facial creases caused by repeated muscle movement. To illustrate, imagine repeatedly folding a smooth sheet of paper along the same line. This crease remains regardless of efforts to smooth the paper.
Neurotoxins also have many other cosmetic applications. Examples include erasing neck lines, smoothing chest wrinkles, facial slimming, relief from teeth clenching, lifting the nose tip and calming excessive sweating.
