What causes lichen skin disease?

Lichen dermatosis sounds like moss growing on the skin, which makes people frown. In fact, the scientific name of this skin disease is pityriasis lichenoides. Its appearance may make the skin rough and dry, accompanied by itching, making people feel very uncomfortable. The cause of lichen dermatosis is not a single one, but usually related to multiple factors.

Lichen dermatosis may be related to an abnormal response of the immune system. The immune system is like the body's "security guard". When it mistakes its own skin cells for "invaders", it may trigger an inflammatory response, leading to lichen-like changes on the skin. Some people are born with a more sensitive immune system, which may make them more susceptible to this type of skin disease.

Psychological factors may also be an important cause of lichen dermatosis. When you are under great stress and emotional tension, your body will secrete more stress hormones, which may affect the health of your skin. Just like a rubber band that is stretched tight for a long time, your skin may also have problems under stress. Maintaining a good mental state has a positive effect on preventing and alleviating lichen dermatosis.

Environmental factors cannot be ignored. Dry climate, excessive sun exposure or long-term skin contact with irritants may be the cause of lichen skin disease. The skin is the first line of defense of the human body, and changes in the external environment will directly affect its health. Imagine that if the skin is exposed to dry air for a long time, it will be like water-deficient land, prone to cracking and roughness.

Of course, genetic factors are also an important aspect of lichen skin disease. If someone in the family suffers from a similar skin disease, the risk of the offspring getting the disease will also increase. This is like a "little secret" hidden in the family gene pool, which may be activated under certain conditions.

The causes of lichen dermatosis are relatively complex and are usually the result of multiple factors. In order to reduce the risk of disease, it is recommended that you maintain good living habits, pay attention to skin moisturizing and sun protection, and moderately relieve stress. If symptoms have already appeared, it is very important to seek medical attention in time. I hope everyone can have healthy skin and stay away from the troubles of lichen dermatosis.
