Photodermatosis: Understanding and Treating Photosensitive Skin Reactions

Photodermatosis, also known as actinodermatosis, is a group of skin diseases that result from the skin being overly sensitive to sunlight or other sources of ultraviolet (UV) radiation. These reactions can come in a variety of forms, from minor redness and itching to more serious conditions such as sunburn or dermatitis.

The causes of photodermatosis can be varied. One of the most common causes is a violation of the protective function of the skin, caused by genetic factors or environmental influences. Some people have increased sensitivity to UV radiation due to skin pigmentation disorders or the presence of certain genetic mutations that make the skin more vulnerable to sunlight.

Symptoms of photodermatosis can vary depending on the type and extent of the disease. Some of the most common symptoms include skin redness, burning, itching, blistering or blistering, peeling and changes in pigmentation. In some cases, painful sores or sores may appear on the skin.

The diagnosis of photodermatosis is usually based on clinical examination of the skin and the patient's medical history. The doctor may also do special tests, such as photopatch tests, to determine which light sources the skin reacts abnormally to. This helps rule out other possible causes of skin reactions.

Treatment for photodermatosis is aimed at reducing symptoms and preventing recurrent attacks. This may include using sunscreens with high levels of UV protection, wearing protective clothing, and avoiding sunlight during periods of peak intensity. For severe or chronic forms of photodermatosis, creams or medications may be prescribed to help reduce inflammation and symptoms.

Prevention of photodermatosis also plays an important role in managing this condition. This includes proper sun protection, wearing protective clothing, avoiding sun lamps and tanning beds, and monitoring medications that may increase the risk of photosensitive reactions.

Photodermatosis is a common condition that can significantly affect patients' quality of life. Therefore, it is important to consult a dermatologist if you experience suspicious symptoms or sensitivity to sunlight.

In conclusion, photodermatosis is a skin condition that manifests itself as photosensitive reactions to sunlight or UV radiation. It can be caused by various factors, including genetic predispositions and environmental exposures. Diagnosis is based on clinical symptoms and specific tests, and treatment includes protective measures and medications to reduce symptoms. Patients are also advised to prevent photodermatosis by using sunscreen and limiting exposure to sources of UV radiation.

Seeing a doctor and following the recommendations will help patients with photodermatosis manage their condition and enjoy a more comfortable life in sunny conditions.

Photodermatoses is the name of a disease that combines several groups of painful skin conditions associated with increased sensitivity to ultraviolet rays. It is an immunopathological process and occurs as a result of exposure of the skin to the sun or an artificial light source.

In response to skin contact with ultraviolet light, histamine is released, causing redness and swelling. Swelling and inflammation appear. Due to the aggressive action of sunlight, itching, irritation, peeling, blisters, pigmentation and even tumors that are prone to malignancy appear.

Manifestations of the photoimmune inflammatory process in some skin phototypes (background reaction to the sun) are characterized by moderation and relapses, while in others they are persistent and malignant. The factors that cause these phenomena can be different: infection, chemicals, foreign bodies getting under the skin, insect bites, etc. Lyell's syndrome is also called solar urticaria: against the background of hyperemia, a skin reaction occurs, consisting of large and small blisters. Most often, sunburns are localized on open areas of the body (face, hands, legs).
