Generally speaking, the most likely cause of facial allergy is cosmetics, so stop using cosmetics immediately. Of course, we can't rule out the cause of mites. We can wash the pillows, quilts and sheets at home, dry them and get rid of mites. Another possibility is food allergy, so it is suggested to stop eating new food in the near future. In short, rule out all possible causes of your allergy and stay away from it.
Second, pay attention to the regulation of digestive tract function.
When there is a problem with the function of digestive tract, the red oxygen on the face caused by allergy will be aggravated. Therefore, during the period of allergy, it is necessary to ensure the smoothness of digestive morality in order to eliminate the wet poison in the body in time. We can promote digestion by eating more fresh vegetables and fruits or coarse grains and foods rich in cellulose. If constipation occurs, you can choose to make tea with a small amount of senna to relieve the symptoms. Adjust the digestive tract, and the allergic symptoms will be alleviated.
Third, develop correct eating habits.
It is best not to eat irritating foods, such as onions, ginger, garlic, peppers, parsley and other seasoning dishes during allergies, and don't drink alcohol. It is best not to eat instant noodles, canned food, beverages and other foods containing more preservatives and additives. Facial skin allergy is sometimes caused by exuberant sebum secretion, so some greasy foods such as animal fat, animal meat and fried foods should also be avoided as much as possible. You can eat some fruits and vegetables that reduce sebum secretion, such as cucumbers, apples and bitter melons. Correct eating habits help to relieve facial allergies, redness and itching.
Fourth, carry out cold compress and wet compress.
After discovering that you are allergic, you can apply cold compress and wet compress to your face, and take some pure water at about 4℃. Pure water can refrigerate ordinary water and prepare four to eight layers of gauze. If there is no gauze, you can use a towel instead. Soak the gauze completely in water, take it out and twist it until it doesn't drip, and wet apply it to the face 15 to 20 minutes. This method can make blood vessels contract rapidly and relieve allergic symptoms. Be careful not to apply cold compress all the time, but to apply it at intervals.
Five, oral antiallergic drugs
If the above methods still have no relief effect, it is suggested to use some antiallergic drugs such as desloratadine, levocetirizine or chlorpheniramine appropriately.
Sixth, seek medical attention in time.
If it is a large area of allergy, if it is serious, you should seek medical attention for allergen testing in time. Regular treatment can quickly solve allergies and avoid allergies again.
