There is a red mark on the chin which does not hurt or itch

According to statistics, about 20% of people have experienced allergic reactions on their facial skin to varying degrees. When the skin is allergic, it is often very painful and itchy, and may be accompanied by symptoms such as redness, swelling, blisters or scabs. Some people may also experience facial tightness and numbness. There are many reasons for facial skin allergies. The antigens that induce allergic reactions are called allergens. There are many antigens that can cause allergic reactions. They can cause allergic reactions in the skin through inhalation, injection, ingestion, etc.

1. The main causes of facial skin allergies

1. Inhaled allergens such as pollen, catkins, dust, mites, fumes, paint, car exhaust, gas, cigarettes, etc.

2. Ingestible allergens such as: milk, eggs, fish, shrimp, foreign proteins, alcohol, drugs, antibiotics, anti-inflammatory drugs, sesame oil, essence, onion, ginger, garlic and some vegetables and fruits.

3. Contact allergens such as: cold air, hot air, ultraviolet rays, cosmetics, shampoo, soap, chemical fiber products, plastics, metal accessories, bacteria, mold, viruses, etc.

4. Injectable allergens such as penicillin, streptomycin, xenobiotic serum, etc.

5. Self-tissue antigens whose structure or composition has been changed due to mental stress, work pressure, microbial infection, ionizing radiation, burns and other biological, physical and chemical factors, as well as self-hidden antigens released due to trauma or infection can also become allergens.

2. Precautions for facial skin allergies

1. Avoid using too hot water when washing your face. It is best to use running water and warm water when washing your face. After washing, you can apply a cold towel. Avoid using hot water.

2. Avoid eating. You should also pay more attention to what you eat. You must not eat barbecue, no matter how delicious it is, as it can cause great damage to sensitive skin and cause it to become severely dehydrated. Eat less fried food. It is better to avoid spicy food. Also drink less alcohol.

3. Avoid staying in a dry environment for a long time. For example, the dryness of air conditioning is ten times that of the desert. Being in such a dry environment for a long time is very detrimental to the recovery of sensitive skin. Therefore, try to find ways to increase the humidity in the air.

3. You should not eat these when you are allergic

Spicy and hot foods can stimulate the body. Such foods as alcohol, strong tea, coffee, chili peppers, garlic, leeks, dog meat, sparrow meat, shrimps, etc. should not be eaten. In addition, sweet and warm foods, such as mutton, chicken, pumpkin, taro, longan, chestnut, carp, silver carp, etc. should also be eaten less.

4. You should eat these to prevent allergies

1. Honey

Drinking a spoonful of acacia honey every day can keep away seasonal allergy symptoms such as rhinitis, asthma, itching, cough and dry eyes.

Friendly reminder: Do not use processed honey. Processed honey is mostly processed with saccharin or blended with third-party ingredients. Not only is it ineffective, it can also aggravate allergic symptoms.

2. Carrots

The beta-carotene in carrots can effectively prevent allergic reactions such as pollen allergies and allergic dermatitis. Japanese experts discovered through research on laboratory mice that beta-carotene can regulate the balance within cells, making it less likely for laboratory mice to have allergic reactions.
