The colors are added in, of course, with it being an electron microscope image. Another picture:

    See that little hook at the point? This is from penetrating skin ONCE.

    This is why you don’t re-use needles folks!

      I can’t believe it’s that fine or how easily human skin can bend it. I guess our skin is a better protector than I’d given credit.

      All these images are super interesting and I’m truly glad they got posted.

      In that last one, you’d probably be able to see the bent over tip with the naked eye. You’d certainly be able to feel it if you ran your finger over it. It would take some force and would be pretty painful to use.
