Very often people face such a problem like redness of the skin under the influence of sunlight, which arises at all from the fact that they were sitting under the sun. Similar symptoms are characteristic of such a disease as photodermatosis. About this disease and tell our site to your readers.
What is photodermatosis
Photodermatosis is the skin reaction to the effects of sunlight, which arises as a result of the influence of external or internal factors. In life, she has many other names, for example, allergy in the sun, photodermatitis, solar urticaria and other. The cunningness of this disease is that it is difficult to determine independently, since in most cases it looks like a simple solar burn, and other symptoms are easy to confuse with any disease in general.
Symptoms of the disease
The most common signs of photodermatosis are:
- redness of the skin like when burning in the sun;
- Formation of blisters with pus;
- In cases of severe allergy, other responses may be observed, for example, dizziness, temperature rise, weakness;
- Those who suffer from complex forms of solar urticaria sometimes arise bronchospasm, lowering blood pressure, loss of consciousness.
Causes of the disease
Based on the name «Allergy in the Sun», You might think that the sun's rays can really cause an allergic reaction. However, doctors hurry to dispel this myth, because it is only the name of the disease, and there is not a single substance that can provoke allergies in the rays. In fact, they only provoke the development of symptoms, and the cause can be either internal changes in the human body, or external reagents.
so, Exogenous photodermatitis (external) - caused by human use of any cosmetics, spirits and other products that include substances that are poorly reacting to the sun. For example, the sunscreens or lippers may be contained eosin, para-aminobenzoic acid, retinoids, salicylic acid, sandals, mercury preparations or phenols, which cause an allergic reaction when exposed to sunlight.
Endogenous photodermatitis (internal) - arises against the background of internal diseases. It can provoke violations in adrenal, liver, kidneys. Also, there is a role, violation of other metabolic processes in the body, decrease in immunity, the total absundability of the body.
In addition, solar allergies can manifest As a result of the use of special groups of medicines, in the side effects of which indicated «May call photosensitization». For example, it may be Antibiotics, Oral contraceptives, antihistamine preparations, aminazine, cytostatics and other substances. By the way, Ibuprofen and aspirin Also related here.
There is still an opinion that its sources can be Some products, Especially citrus, such as tangerines, Grapefruits or oranges. Be careful to them and, if possible, do not eat them before entering the street.
I am glad that photodermatosis is. Rather, a single phenomenon than chronic disease. And therefore, as a rule, it arises once, after which it is only necessary to adhere to the basic rules of behavior under the sun.
However, if you know that it is subject to such a disease, I recommend the readers of the MirSovet to adopt such preventive measures:
- Before leaving the street, use creams with SPF protection, 30 minutes before. Give them time to absorb. The same applies to any other protective equipment, do not apply them a few minutes before the exit, and even more so on the beach;
- Carefully read the composition of the cosmetic tools you use. If there are at least some of the above substances, it is better to give up them;
- If you are an allergy, a few days before the planned rest, we offer antihistamines, however, before this consult your doctor;
- After leaving the water, we immediately wipe dry, as water droplets lead to even greater lighting compared to dry skin;
- Try to follow the basic rules of behavior under the sun in order to avoid his destructive impact (take into account the time of walking, the duration of stay under the sun and so on).
Methods of treatment
If you still encountered photodermatosis, you can use some kind of techniques to start. For example, attach to the damaged place of cabbage sheets, raw cucumber or potatoes, these products help to cope with itching and remove redness.
From medical drugs it is better to use ointments containing Lanolin in its composition, Panthenol, Zinc or methyluracyl.
It happens that photodermatosis is not manifested immediately, but a few hours after being in the sun (even after 32 or 72 hours). One of the rare cases when a person reacts not only to direct sunlight, but even covered with a red rash indoors, well-lit by the sun through the window. In this case, it makes sense to consult a doctor who will help determine the real reason for its occurrence.
As we have already spoken, it can be caused by internal violations, and therefore the treatment of photodermatosis will be primarily dependent on the treatment of the main disease, which cannot be done independently.
Therefore, with any suspicions that you have some other problems in the body, contact a dermatologist, an allergist or immunologist. They can assign even a special hormonal ointment, which will quickly remove external signs of photodermatosis.
And in no case should not think that if he manifested himself once, then you will never go out again in the sun. Yes, in very rare cases, this disease is repeated again and again, but it happens very rarely and requires special treatment. But, as a rule, one course of treating photodermatosis allows you to get rid of the disease once and for all.
If Fotodermatosis is run, it can lead to the development of eczema. So, try to keep track of how your skin behaves after sunbathing and, in the case of which, do not slow down with a visit to the doctor. Adhering to uncomplicated rules, you can easily prevent photodermatosis.
