This makes me think of an authentic self. But authenticity is more than that, it can be applied to material goods too.

So genuine, true, mask off/unmasked...

How about unbridled representation of true to self?

This is a tough one.

That which is real and genuine, transparent and natural, truth without deception or hidden intent motif agenda

Authenticity means being true to who you are, even when pressures or expectations try to push you otherwise. It’s about staying genuine to your values, beliefs, and feelings, regardless of the situation. Being authentic is not just about honesty to others, but also being honest with yourself, embracing both your strengths and vulnerabilities.
