Micro Expressions

Micro expressions are very subtle movements of facial muscles of 0.5 seconds or shorter.
There are seven basic micro expressions which show on people's faces around the world: happiness, contempt, disgust, anger, fear, surprise and sadness.
To be noted, that these are not proof of lying, these are signals and can be used in a reliable way to detect lies.

Micro Expressions are often taught in slow motion, frame by frame.

Happiness 

◆To detect a real or fake Smile or Happiness, try to notice and observe these reactions:
   1) Curled Lip Corners (both lip corners must be curled).
              Lip corners go upwards in a symmetric way at the same time,  at equal heights. It means                      they feel a small pleasure and that they like what they hear, smell or see.
   2) For a real Smile (not just happiness alone) eye cover fold drops and stretches a bit due to                            contraction of the "Orbicularis oculi" muscles which is also called a "Duchenne Smile".
   3) In a real smile the eyebrows go a little bit downwards but if the eyebrows go upwards it would                    mean that the experience of happiness isn't true, so it's a fake smile.

Contempt (Superiority)

◆ When you see one side of the lip go upwards then it would mean that the person is expressing              contempt.
    1.) It would mean that the other person is feeling "superior" and does not fully accept you.                  Note: In happiness both lips go upwards in a symmetrical way,

Disgust

◆ When you see wrinkles around the nose (and sometimes upper lip), top lip rising ( and sometimes      with visible teeth OR with the lower lip pressing the upper lip). These are subtle signs of disgust.         You should also look for these signs too:

    1.)Eyebrows go down and there are wrinkles around the nose.
    2.)Wrinkles around the nose distinguishes disgust from all other micro expressions.
    3.)It signifies that you are trying to close your nose without using your hands.
    4.)WHEN WITH CLIENTS,  It would mean that they do not like those specific details about your          product which you just mentioned.
