Tanning dermatitis is a common summer skin disease commonly known as sun spots or UV allergy. It is an acute phototoxic reaction of the skin due to skin redness, blistering or blistering of the skin in the exposed area after excessive exposure to sunlight. The mechanism is that when the skin tissue is exposed to light, antigenic substances are formed to sensitize the body, resulting in an allergic reaction.
Who is most likely to develop solar dermatitis?
The occurrence of solar dermatitis is related to light intensity, exposure time, individual skin color, body type, and race. It usually occurs in late spring and early summer in children, women, skiers and water workers, and people who work outdoors for long periods of time.
Symptoms of solar dermatitis
After a few hours to more than ten hours of sun exposure, erythema and edema with clear boundaries appear on the exposed areas (face, front of neck, both upper limbs, etc.), and in severe cases, blistering, rupture, and erosion may occur, followed by gradual darkening and desquamation of the erythema, leaving pigmentation or hypopigmentation.
There is a burning or stinging sensation in the sensation, which often affects sleep. If the sunburn is extensive, a few patients may also develop systemic symptoms such as fever, headache, nausea, malaise and discomfort, or even palpitations, delirium or shock. It is also possible to stimulate rashes of polymorphic sun rash, solar urticaria, delayed cutaneous porphyria, lupus erythematosus, herpes simplex, vitiligo and other diseases.
It is inevitable that people with fragile skin will get heliodermatitis during the hot summer months when the sun is shining and UV rays are strong. With solar dermatitis, the first thing you need to do is pay more attention to your diet to prevent eating the wrong things that can aggravate your skin problems.
Photosensitive substances can cause solar dermatitis
The actual fact is that you can find a lot of vegetables in your body that will break down and accumulate in your body, and when your body is exposed to light, it will induce solar dermatitis.
The first thing you can think of is lemon, but some common vegetables, such as amaranth, rape, amaranth, celery, eggplant, potatoes, cauliflower, fresh fungus, etc., all contain photosensitive substances, although it is usually recommended that we eat more vegetables and fruits to replenish vitamins, but after getting solar dermatitis, you must pay attention to less intake of photosensitive vegetables and fruits.
This is the first time I’ve ever seen this.
1, avoid stimulating food
The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things.
2, avoid eating greasy food
Too much intake of greasy food will promote the secretion of sebaceous glands, aggravating skin problems, and also pay attention to eating less creamy sweets and foods that taste too salty.
3.Control fat intake
The fat in the diet should not be too much, otherwise it will aggravate the symptoms, the diet containing more sugar can promote the production of more fat after fat xenobiotic, so you can not eat more, you can give a high protein diet.
4, more vitamin supplement
The people of solar dermatitis should be supplemented with vitamins, especially foods containing vitamin A to eat in moderation, such as pig liver, carrots, egg yolk, etc., to improve the sebaceous keratinization abnormalities of hair follicles and prevent hair follicle blockage.
Conditioning solar dermatitis, pay attention to.
1, strengthen outdoor exercise, enhance physical fitness, try to avoid sun exposure, and be prepared for sun protection when you go out.
In the summer months of June to September, 10 to 14 o’clock every day is the strongest period of daylight in the ultraviolet radiation, medium wave ultraviolet B is the culprit of solar dermatitis, this period should try to avoid going out. When you must go out, you must wear long sleeves and long pants, wear a sun hat or play umbrella, so that the sun protection effect is better.

3, appropriate skin massage, massage can promote the metabolic function of skin tissue, and can enhance the skin’s resistance to melanin deposition.
