For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.
Pretty sure that's just a weird shadow from some unfortunate lighting choices. If you look closer you can see the skin move but the seam stay in the same place.
I think the shadow is too sharp for that. My guess is that it's a filter that is supposed to brighten the face with a sharp edge.
