When the skin is allergic, there will be reactions such as redness, swelling and itching. At this time, if not treated in time, the skin will be obviously swollen and even blisters will appear. Even if the allergic symptoms are relieved in the future, it will leave obvious pigmentation, which is often difficult or permanent.

Remember, when the skin has allergic symptoms, don't scratch the affected area. At this time, one-step first aid can control the disease to the maximum extent.

Song Ping, the attending physician of dermatology department of Beijing Guang 'anmen Hospital of Traditional Chinese Medicine, said: When the skin is allergic, we should apply a cold towel to the skin at the first time, because after the skin is allergic, some erythema will appear on the skin, which will lead to swelling again, with this burning sensation. At this time, we can contract the dilated capillaries, which can reduce the inflammatory reaction and reduce this exudation. At this time, we will go to the hospital for treatment after cold compress.

Remember, when the skin has allergic symptoms, apply a wet towel to the affected area. Only in this way can you contract blood vessels, calm the skin and reduce inflammation.

Usually pay attention to stay away from your allergens. If you are at home, increase the humidity of the air. Eat more fruits, such as apples and pectin, and eat more fruits.

Many people are willing to prescribe a prescription for themselves after skin allergy, so they apply ointment such as Piyanping. It was really effective at that time, but after a long time, you will become dependent on applying such ointment. After you stop taking the medicine, your skin may swell again, so we think that if your skin has allergic symptoms, don't be afraid of trouble, or go to the hospital.

Special reminder: once allergic asthma occurs, you can take a cup of hot water, put your mouth close to the mouth of the cup and breathe the hot air of the water, which will help relieve the symptoms of asthma.
