Sun allergy: symptoms

Benign summer lucite, polymorphic lucite, solar urticaria ... The symptoms of sun allergy are different depending on the type of allergy.

Here are the main symptoms by type of solar allergy:

1 - The benign summer lucite.

The summer lucite never touches the face, but only the body (especially the shoulders, the cleavage, the backs of the feet ...). It is manifested by the appearance of tiny vesicles that are under the skin, accompanied by redness and itching.

2 - The polymorphous lucite.

The polymorphic lucite, as its name suggests, can cause eruptions of very different nature (spots, vesicles, plaques more or less extensive, nodules ...) that appear on the skin even in case of sunshine low.

3 - Solar urticaria.

In case of solar urticaria, oval and red blisters appear in the deepest layers of the skin. This reaction is manifested at the beginning of the sun exposure, after a quarter of an hour, and can be quite violent and even give general signs (malaise, difficulty breathing ...).
If solar urticaria is mild, it disappears fairly quickly once you return to the shade and avoid exposure to the sun. However, she is easily recidivating.

4 - Photosensitization.

Symptoms of photosensitivity occur rapidly during sun exposure. These are red vesicles accompanied by severe itching.
Rashes normally go away 48 hours after sun exposure.

The skin is a very important tissue of the human body. If it were spread on the ground, it would cover an area of 1.5 to 2 m² (in adults).

17 Skin Info

The skin represents about 15 to 20% of our body weight. For a person who weighs 75 kg, this amounts to a weight of almost 14 kg.

17 Skin Info

The skin has on average 6 million cells, 15 sebaceous glands and 100 sweat glands per cm².

In total, the skin includes 3 layers in total: epidermis, dermis and hypodermis . Each layer has very different functions.

17 Skin Info

The upper layer, the epidermis, protects us mainly from heat, cold and chemicals . It is covered with very many bacteria that live on the surface of the epidermis.

17 Skin Info

The epidermis is particularly thick on the hands and feet where its diameter can reach up to 2 mm . The average thickness of the epidermis is 0.05 mm.

17 Skin Info

The cells of the epidermis multiply at such a speed that the complete epidermis is completely renewed in the space of only one month . The body loses each day between 10 and 15 grams of dead cells.

Below the epidermis is the dermis : it consists of a very dense network of collagen fibers that give the skin its elasticity and deformability, as well as its resistance to tearing .

17 Skin Info

In the dermis are blood and lymphatic vessels, nerves, cells of the immune system, hair roots, multiple skin glands and pressure receptors (for the sense of touch).

When it is cold, the small blood vessels of the dermis "tighten", when it is hot they widen. This also has an impact on the color of the skin .

17 Skin Info

The layer below the dermis, the hypodermis, consists mainly of fat and connective tissue. The grease serves as a reservoir of energy and thermal insulator .

17 Skin Info

The hypodermis allows the mobility of the skin and connects it to the underlying structures.

On the hands and especially the feet, the fat of the hypodermis also serves as a " mattress " to protect the bones and tendons that it covers.
