Key Differences
An innie belly button is characterized by its inward indentation, making it look like a small pit, whereas an outie appears as a small bulge.
In terms of commonality, innies are more prevalent among the population, while outies are less common and often noticed due to their distinctive protrusion.
The formation of an innie or outie is generally determined by the way the umbilical cord heals and scars after birth, not by how the cord is cut, as is a common misconception.
In terms of hygiene, innies may require more careful cleaning due to their depth which can trap lint and bacteria, while outies are generally easier to clean because of their exposed nature.
While the type of navel someone has is mostly a cosmetic difference and typically doesn’t affect health, outies can sometimes be associated with umbilical hernias, which may require medical attention.
