Hidden Pattern on Your Skin

The skin of all human beings is covered in stripes. They're called Blaschko’s Lines, and they cover the body from head to toe. We just can't see them with the naked eye. They only become visible under UV light. However, these stripes, which run from head to toe, can be seen in people with certain skin conditions and even chimerism. It's almost as if our skin is secretly wearing a UV-illuminated, body-hugging pattern, just waiting to be revealed.
