Why is the skin allergic in rainy days? What should I do?

Skin allergy is also called "sensitive" skin. From a medical point of view, skin allergy mainly refers to the abnormal phenomena such as redness, itching, peeling and allergic dermatitis when the skin is stimulated by various cosmetics, chemicals, pollen, certain foods and polluted air. Sensitive skin can be said to be an unstable skin, which is always in a state of high alert. Special attention should be paid to its care.

Symptoms caused by skin allergy:

Diseases caused by skin allergy include urticaria, contact dermatitis and atopic dermatitis. Because some of these diseases, such as contact dermatitis, are at different stages of development, the principle of medication, especially the principle of external use, is completely different, and improper treatment will aggravate the symptoms; Although some diseases such as urticaria can heal themselves, if the condition is serious, it may cause laryngeal edema and anaphylactic shock. Therefore, Wang Dafu suggested that patients can take oral antihistamines to treat themselves unless they have mild urticaria. In other cases, especially when the symptoms are still not relieved after taking the medicine, you must go to the hospital for treatment instead of saving trouble for a while.

Why does the skin have skin allergy?

1. With the increase of age, the secretion function of the skin will deteriorate, the skin will become thinner with the passage of time, and its protective layer function will also weaken.

2. Long-term exposure to sunlight or air pollution, smoke, dust, ultraviolet rays UVA, UVB and infrared rays will damage the skin, because the free ions they produce will damage the lipid protective layer of the skin.

3. Improper damage of inferior cosmetics or drugs.

4. Physiological factors, stress, mental stress and depression will weaken the natural resistance of the skin and slow down its self-repair function. Such as endocrine disorders.

5. Weather: In the face of weather changes, the skin also needs extra adaptation. For example, in cold weather, if the skin is not adequately moisturized, it is very vulnerable.

6. Additives: Some ingredients in skin care products, such as preservatives, dyes, emulsifiers, spices, etc., may make the skin sensitive.

7. Specific physique

What emergency measures should skin allergy take?

1, all cosmetics should be stopped to give the skin a buffer time. If you usually use low-sensitivity skin care products, you can continue to use them; If it is the first time or occasionally allergic phenomenon, and you don't use low-sensitivity skin care products on weekdays, then you should choose special skin care products with anti-inflammatory and calming effects and use them after washing your face with water. If there is persistent redness, you should go to the hospital for desensitization treatment. You can also fully moisten saline for injection and apply it to sensitive parts of the face with cotton or gauze. This normal saline for injection has high safety and good permeability, and has the functions of detumescence, detumescence and skin stabilization. Generally speaking, the red will disappear in a few days.

2. Strengthening skin resistance is also an effective basic countermeasure, such as adequate sleep, adequate and balanced diet, harmonious mood, staying away from polluted environment and allergens, and reducing skin irritation. Mild sensitivity will recover quickly as long as it is handled properly, and you need to seek medical advice quickly when it is serious.

3. Don't use drugs without authorization. Don't go to the drugstore to buy the affiliated corticosteroid ointment without a dermatologist's diagnosis, which is harmful to the skin. Because it is effective in inhibiting inflammation, but long-term use will have side effects and endanger health.

For topical hormone drugs for the treatment of skin allergy, such as Piyanping, Youduolu (hydrocortisone butyrate) and Ai Luo pine (mometasone furoate), attention should be paid to:

1. Don't apply it to your face, because this medicine will cause epidermal atrophy and pigmentation, and cause irreversible damage to facial skin.

2. It should be used after a doctor's definite diagnosis, because these drugs are not effective for all skin itching. It is a common misunderstanding for patients to mistake tinea corporis and scabies for allergies and blindly use these drugs.
