Welcome to CCC.
It is not the face but the eyes and those never looking others in the eyes never know unless they feel the negatives vibes which can be overwhelming.

The face is also infected by weight, skin diseases, hard labour, being outside, bad food, medication...

Fake smiles are also felt and are those strong if they hide? Most likely they are considered fake and if not people say they shocked if the fake smiler commits suicide. Nothing makes that lonely as being forced to pretend.

You are two years on Steemit, not a newcomer meaning you are not allowed to use the hashtag #newcomer.
Please, remove it and take care of your own writing.
