Micro-expressions are brief, involuntary facial expressions caused by a certain emotion experienced by the person. These expressions are shown on the face, and are universal in the sense that every human being, no matter what origin, or where they live it will be the same as everyone else.

Micro-expressions are controlled by the muscles frontalis, corregator and risorius in the face. These movements are fractions of a second long, around 1/25 to 1/15 of a second.

Paul Ekman is known as the for-leading Psychologist that studies these micro-expressions (Humantill).
