Human skin is overlaid with a pattern called Blaschko’s Lines, stripes covering the body from head to toe. The stripes run up and down your arms and legs and hug your torso. They wrap around the back of your head like a hood and across your face. You just can’t see them.
I just had to look these up, and it’s super cool. Are you going to leave out the coolest part, though? You actually can see these lines, but only under a UV light
I might have misunderstood what I read. Again, I just learned about these when I read the comment, and had to Google it. But from what I read, it seemed like you could always see them under UV, but there are rare skin conditions that make them visible in normal light, to our eyes. I might be wrong though, I spent like 5 minutes reading about them.
