What are the causes of skin allergy

summary

Skin allergy is also known as "sensitive" skin. From the medical point of view, skin allergy mainly refers to the abnormal phenomenon of skin redness, itching, peeling and allergic dermatitis when the skin is stimulated by various kinds of adverse reactions, such as cosmetics, chemicals, pollen, some foods, polluted air, etc. Special attention should be paid to its nursing. Let's share with you the causes of skin allergy.

What are the causes of skin allergy

First: age: perhaps the growth of age is an important reason for skin sensitivity. Some people's skin was not sensitive a few years ago, but it has become sensitive in recent years. This is because there is a weak acidic sebum membrane on the surface of young and healthy skin to keep moisture and protect the skin from external damage. However, with the growth of age, this sebum membrane is not as healthy as before, so that some sensitive substances are easy to invade the skin.

Second: Pets: sensitive skin is easy to be allergic to the fur of domestic pets. This kind of allergy caused by pets is mainly due to the proteins secreted by the fat glands of cats and dogs. When pets lick their hair, these proteins stick to the fur, and then fall into the air, and then adhere to the human skin.

Third: seasonal change: due to various environmental factors, bacteria spores and pollen and other allergens scattered in the air will release a large amount of histamine, a compound that can be found in almost all human tissues, causing facial skin allergy.

matters needing attention

When going out at ordinary times, we should take protective measures as far as possible, especially when the seasons change. When going out, we'd better wear long clothes and trousers to prevent too much naked skin from causing allergy.
