What are corns?

Corns are dead, thick skin that form when the pressure point against the skin has a circular motion. This creates an upside down cone of hard skin which can cause pain or serious discomfort. The corn has a central core of hard skin which puts increased pressure on deeper tissues. Until the corn is removed, the pain and discomfort will be present.

Why do corns form?

When an abnormal pressure point traces an elliptical path during the rubbing motion against the skin creates an upside down cone of thick, dead skin with a central core of hard skin.
