Mostly True Unknown

The text states that all human beings have skin covered in stripes called Blaschko’s Lines, which cover the body from head to toe but are invisible to us.

Blaschko's Lines are described as patterns resulting from embryonic cell migration. They are usually invisible but can become apparent under certain skin conditions. This evidence suggests that all humans possess these lines, although they are not typically visible. They do not follow body systems or functions like dermatomes, nerves, or blood vessels, but rather, they follow developmental patterns.

Blaschko’s Lines cover the body from head to toe.
Blaschko's Lines indeed cover the entire body, following patterns of embryonic development. However, their visibility is limited to specific skin conditions, so they aren't typically apparent throughout the body without medical conditions highlighting them.
