What should I do if my skin is thin and easily allergic?

Allergy, also known as allergic reaction, is an abnormal immune response. It refers to the allergic reaction of a specific body constitution to external substances that normal people can tolerate, such as pollen, pet dander, eggs, milk and other items. People with allergies often get bumps and the allergic areas will itch. Allergies cannot be ignored. Minor allergies may cause major diseases, so allergies should be treated in a timely manner. So how should we treat thin skin that is prone to allergies? Do you need some special care for your face?

An allergic reaction is a reaction that occurs when an immune body is stimulated by the same substance again. The reaction is characterized by rapid onset, strong reaction, and rapid disappearance; it generally does not destroy tissue cells or cause tissue damage, and has obvious genetic tendencies and individual differences. Allergic reaction is an immune dysfunction disease, which refers to a group of clinical syndromes caused by the release of large amounts of allergic mediators by mast cells and alkaliphilic granulocytes after the combination of foreign antigens and specific antibodies in the body. The main manifestations are local vasodilation, increased vascular permeability, organ smooth muscle contraction and enhanced glandular secretion.

Allergies often occur in a relatively fixed group of people because people with allergic constitutions have congenital immune dysfunction, which is often inherited. In other words, people with this constitution may suffer from allergies throughout their lives.

Of course, people with allergic constitutions do not necessarily develop allergies. This is determined by the mechanism of allergies. When a person with an allergic constitution comes into contact with an allergen (antigen) for the first time, the body will not produce allergic symptoms, but a corresponding specific antibody will be produced in the body. When this specific antibody accumulates to a certain amount, if it comes into contact with the antigen again, the specific antibody will combine with it, causing the body's mediator cells to degranulate and release a variety of mediators, thereby producing a series of allergic symptoms.

It can be seen that there is a condition for the occurrence of allergies, which is that there must be repeated exposure to the same allergen. Knowing this, it is not difficult to understand why people who are allergic to certain pollen only suffer from allergies in spring and not in other seasons. This is because these flowers only bloom in spring and it is only possible to come into contact with their pollen in spring. Substances that cause allergic reactions are called allergens, such as pollen, indoor dust, fish, shrimp, milk, eggs, penicillin, sulfonamide, quinine, etc.

For people whose faces are prone to allergies, they should take precautions in advance during the allergy-prone season, prevent contact with air, pay more attention to facial cleansing, use less irritating cosmetics, and be more careful when using skin care products. Do not blindly use unhealthy skin care products. Allergies should be treated promptly, don't delay, go to the hospital for examination in time.
