Causes and treatments for chronic sunburn Treatments for chronic sunburn

Solar dermatitis is commonly known as sunburn. Ultraviolet rays are very strong in the summer, and exposure to the sun may cause redness, burning, itching or stinging of the skin. This causes sun spots. Sun spots are difficult to treat and the effect is relatively slow. So what are the specific causes of sun spots?

Causes and treatments for chronic sunburn

1. Ultraviolet rays. The main cause of sun spots is ultraviolet radiation. There is a kind of melanocyte stem cell in the skin epidermis. Under certain circumstances, it will be activated and release melanin to form spots. The most direct influence in the process of melanin production comes from the ultraviolet rays in the sun. It can activate tyrosinase in melanocytes, produce a series of reactions with tyrosinase in the blood, generate a substance called "DOPA", and then convert it into melanin.

2. Accumulation of toxins. Toxins in the skin can activate cell activity and also produce an oxidation reaction with tyrosinase to generate "DOPA" and release melanin. The pollution, radiation, and smoke that we have to face in life will intensify the oxidation process, making the skin tone darker and more uneven.

3. Cells are stimulated. Pollution, sunlight...all kinds of external threats can cause inflammation of skin cells to varying degrees. In order to repair inflammation, skin cells will naturally react and secrete a tetraenoic acid substance, which will activate tyrosinase to a certain extent and promote the production of melanin.

How to relieve sun spots

1. Bathing: For patients with dermatitis in the acute stage, their capillaries will dilate, which will cause symptoms such as redness, swelling, papules, and blisters on the skin. Once the patient uses hot water to wash, the disease will worsen. Therefore, patients with the disease should use warm water for bathing.

2. Pay attention to diet: The skin of dermatitis patients is allergic, so patients should pay attention to their diet in life and avoid eating foods that may irritate their skin, especially spicy foods such as peppers and coffee. This can avoid aggravating the disease, so people should pay attention and pay attention to it.

3. Avoid blind use of medication: Many dermatitis patients apply high-concentration antipruritic drugs on the skin lesions in the early stage of the disease, but they do not know that these antipruritic drugs contain a large amount of hormones, which will have a very serious impact on the health of the body. Patients must not use drugs blindly, which will aggravate the disease and even cause repeated recurrences.

The above are the causes of sun spots and some methods to relieve them. We all know that the main cause of sun spots is ultraviolet rays, so when we go out in summer, we must pay attention to sun protection, apply sunscreen, and wear a sun hat. If you don’t want to get sunburned, you must take timely first aid measures, such as applying ice to the sunburned area, washing with cold water, not eating spicy food, and eating more fresh fruits and vegetables. Finally, I wish everyone to stay away from sun spots and stay healthy.
