Ear funk/ Ear cheese is one of the less glamorous realities of stretching your lobes.
Ear funk is actually made up of dead skin cells.
All over your body, dead skin cells fall off as new ones grow. This is what is happening with your ears, but the dead skin cells are trapped in place by your jewellery.
When you wear plugs for several days, the dead skin cells start to build up on your jewelry and when you remove the plugs they can be super gross.
To keep on top of it just wash out your ears daily in the shower.
Wearing organic plugs also helps to reduce the odor :)
