Q What causes neurodermatitis? I'm told the skin thickens from scratching — what exactly is this condition?
A The core problem is a vicious "itch-scratch" cycle: repeated scratching and rubbing of an itchy area makes the skin thick and rough (lichenification), and the thickened skin in turn becomes even itchier. It is a chronic eczema fixed in one area, and stress often intensifies the itching.
Detailed Answer
Neurodermatitis (chronic simple lichen) is a chronic eczema in which the inability to resist itching leads to repeatedly scratching and rubbing the same area, making the skin leathery, thick, and rough (lichenification). It often starts with mild itching, but scratching brings only momentary relief while further damaging the skin, making the nerves more sensitive; the thickened skin then becomes even itchier, and this "itch-scratch" vicious cycle entrenches the disease. Stress, anxiety, and insomnia amplify the itch signal and frequently combine with an unconscious habit of scratching.
Korean Medicine Clinic Perspective
At Dongjedang, we view neurodermatitis not simply as a scratching habit, but as a signal from the body's internal environment that has made the skin dry and sensitive. We see mental tension and stress as generating Heart-fire (simhwa), and that heat drying up the body fluids and blood (blood deficiency with wind-dryness, hyeolheo-pungjo), so that when the skin becomes dry it itches as if wind were blowing over it. Beyond merely preventing scratching, we place emphasis on jointly addressing the body's root by moistening the parched skin (nourishing blood and moistening dryness, bohyeol-yunjo) and calming the heat of the mind.
