It's a Snapchat filter , filters can also make someone look younger and various other things .

Well - being as I have an obvious cat make-up picture, I'll respond.
I am playful and imaginative. MIne is a Halloween costume that I worked hard to create. Also., being in theatre, I was rather proud of the make-up job and received many compliments on it. For anyone interested - I have a non-make-up photo among my others on here.
If there are those - such as yourself, who don't "get" it , that would mean to me, that you're likely not my kind of person, as I tend towards the outer edges of the bell curve.

Of course I can only speak for myself - you'd have to ferret out the reasons behind any others.

Don't like it, or understand it ? You needn't look, or concern yourself at all. Fini.
