The skin is the largest, most resilient, and at the same time fragile human organ. It has a complex structure, performs vital functions, and its health is a prerequisite for the well-being of a person. And just like other organs, the skin is highly vulnerable to pathological processes. The peculiarity of skin diseases is that they usually become apparent from the earliest stages. In part, this helps the patient to begin treatment immediately. On the other hand, skin diseases cause severe psychological discomfort, especially when it is impossible to eliminate the symptoms quickly. Therefore, diagnosing and treating any dermatological disease is a necessary condition for returning to a full life. Causes: There are many reasons skin diseases occur. The factors affecting skin can be both internal and external. Each layer of the skin is prone to specific diseases. Some painful conditions, such as burns, can affect all layers of the skin at once; others may affect just one layer. Infectious diseases Skin pathologies can be divided into infectious and non-infectious, but this division is not always true. For example, dermatitis is caused by a fungus that lives on every person’s skin but only manifests when immunity is compromised. Chronic Diseases: Chronic skin diseases are of particular importance in dermatology. Unlike acute infectious processes, they accompany a person for long periods of life and require consistent treatment. They often develop under the influence of various external and internal factors ranging from parasitic invasion to stress. Hereditary Conditions: Certain skin conditions can be inherited. Many people note that problems like juvenile acne are similar in children and their parents. Symptoms: It is easy to suspect a skin disease in yourself or a child. Usually, the skin has a uniform color, moderate moisture, and a smooth surface. A noticeable change in any of these criteria or the appearance of unpleasant sensations, itching, and pain is a cause of concern. Before visiting the doctor, it is crucial to find out how dangerous this condition is and protect yourself and your loved ones. Non-infectious dermatitis, such as psoriasis or eczema, is not contagious. Still, it can significantly worsen a person’s physical and psychological state, so you should see a dermatologist at the first signs of an illness.
