Whether your facial expression is naturally pleasant, or you make a fake smile, the message your body language conveys is critical to your career. 

Your body language and facial expressions send messages about how you feel. Moreover, facial expressions literally express who a person is on some level. Non-verbal communication is sometimes more important than the actual words we use.

Facial expressions can build trust or destroy it. They can appear arrogant or humble and they can give an impression of dominance or weakness. For these reasons, it’s important to know the matter and fix possible issues. Here are important tips on how to use and control your facial expressions:
