Allergy to the sun for children - what to do

Or in other words - photodermatosis.Allergy to the sun in the sun in children is usually caused by excessive ultraviolet rays insolation (long to find the child in the sun without shade) or as a result of artificial irradiation with ultraviolet rays (for the treatment of a number of pathological conditions).

there is a sufficient number of substances, which by their nature are chromophores in human skin, ie,are able to absorb electromagnetic radiation, to which, in this case, the light acts.These include: melanin, keratin, porphyrin, etc. The younger the child, the less developed his protection elements that prevent the accumulation of radiation in the chromophore..This explains the fact that the allergy to the sun in the sun in infants can occur especially hard.

allergy to the sun: causes and symptoms

allergy to the sun: the reasons for which are not limited only to the action of UV radiation, are called polymorphic.Such photodermatosis further accumulation in the skin caused by photosensitizin

g agents that can be both exo- and endogenous character.

exogenous are some drugs (tetracyclines, barbiturates), household chemicals and perfumes, the juice of some plants (angelica, cow parsnip).By endogenous porphyrins are - a substance produced in the bone marrow and make up hemoglobin.

How appears the sun allergy in children?Depending on the duration of radiation exposure, the symptoms can vary in severity.

When a single insolation, lasting 3-6 hours only intense redness stations observed, exposed (I degree), against which can form large bubbles with serous content (II degree).At the touch of painful blisters sometimes accompanied by itching.This display is usually allergic to the sun on the hands, the upper third of the back.neck, the areas of maximum impact.When exposed to high doses developed necrosis of the epidermis and dermis (III degree).

allergy to the sun on their feet, because of the more pronounced subcutaneous fat in children, often manifested by redness, swelling and itching.

However, it should be noted that in certain situations (more often - the genetic predisposition, color) is expressed by how much skin allergies to the sun, not dependent on the radiation dose and on the number of chromophores in the skin.Entering into chemical interaction with electromagnetic waves.they are capable of potentiating the effects of the latter.

allergies that symptoms are not as pronounced flows by type of photochemical reactions and can be of several types:

  1. redness and swelling, against which develops small bubbles - sunburn
  2. large blisters with itching - solar urticaria
  3. grayish papules - solar prurigo.

Pretty rare form that takes a sun allergy in children is the summer prurigo Getchensona.The disease is characterized by the appearance of nodules on the skin, in which the bubbles are.The disease is a long, often lasting winter.

How to treat?

When erythema recommended to use boltushek, wet compresses, creams.May serve as a basis astringents (2% tannin solution, 0.25% solution of silver) and anesthetic (2% solution anestezina) as a cold lotions.It is important to remember that the use of NSAIDs undesirable because they can enhance the photosensitivity.When the vesicles are effective hormonal creams (Afloderm, lokoid, Elokim), a wrap or bandage.

also recommend vitamin therapy (vitamins B, C, PP), antioxidants (tocopherol acetate, tocopherol, methionine).Good results are obtained by using beta-carotene.Also prescribed antihistamine therapy for the child's age (loratadine, tavegil), desensitizing therapy (10% calcium chloride).


apply common methods: dosed sun exposure, stay in the shade in the "peak" of solar activity, protective lotions and gels.

also in early spring or in remission spend phototherapy with UV rays or PUVA therapy, which reduces the risk of photodermatosis.
