Lichenification is the thickening and hardening of skin where it is
constantly rubbed or scratched. The skin becomes leathery, and the normal lines
in the skin become exaggerated, which makes the skin look like bark.
Lichenification often occurs in people who have skin conditions that
cause itching, such as atopic dermatitis (eczema). But it can also occur
in people who otherwise have healthy skin.
