How to prevent skin allergy

Whenever the climate changes, the temperature difference is wide or the season is warm and humid, many women often have skin allergies. Due to various environmental factors, allergens such as bacterial spores and pollen scattered in the air will release a large number of compounds-histamine, which are distributed in almost all tissues of the human body, causing symptoms such as stuffy nose, sneezing, runny nose, itchy throat and swollen eyelids. Therefore, some women may have itchy skin, rash and scales, peeling, different red and white faces, multi-color harmony and other allergic symptoms.

Allergy is a civilized disease. Medically, allergies are divided into four different categories and named after Roman numerals I to IV. The most common types are type I and type IV. Type I is sometimes called "atopy" or "immediate hypersensitivity". For example, human body will react in a few seconds after being bitten by insects, animal hair allergy and pollen allergy will react in a few minutes, and food allergy will take less than 30 minutes. On the contrary, the reaction of type ⅳ allergy is much slower, and the symptoms will not appear until a day or a few days later. For example, decoration allergies and many types of occupational allergies. Therefore, people call it "delayed hypersensitivity".

For skin allergy, antihistamines are often used in clinic. Although it can inhibit the release of histamine, it has limited effect, has no effect on many allergic symptoms, and has side effects. Some antihistamines can make people sleepy and listless. Allergy research experts believe that the most effective measure is to find out allergens and avoid contact with this substance again. However, it is not easy to accurately find the pathogenic factors among 20,000 different inducing factors. In order to detect the allergic reaction of a substance, doctors need to do various skin tests, which is time-consuming and laborious. Moreover, many allergens cannot be completely avoided, such as drugs and insects. Therefore, if people with allergic skin want to have perfect skin, it is mainly necessary to maintain the skin every day and minimize the sensitization of the skin. With the passage of the sun and the moon, the incidence rate will gradually decrease after middle age. Desensitization therapy can be used when necessary. Specifically:

First, do daily skin care. People with skin allergies know that cosmetics can't be used indiscriminately, and many cosmetics are one of the allergens. Therefore, some allergic patients stop using cosmetics. This practice is negative. Proper use of cosmetics and necessary skin care can enhance the resistance of skin to allergens. Unfortunately, allergic patients help beauty salons to do a regular skin test, judge their skin condition, find out the causes of skin problems, and choose appropriate cosmetics according to symptoms. You can also choose anti-allergic essence to guide people, and then make a mask to eliminate sensitivity, reduce the direct reaction of skin to the outside world, strengthen sensitive cell membranes, adjust and reduce skin sensitivity, and enhance skin resistance. In warmer seasons, allergic patients often think that the outside temperature is warmer and sebaceous glands have stronger secretion function, and give up skin care to prevent skin allergy. Or excessive use of facial cleanser and cleansing products with strong fat removal. This will easily destroy the sebum membrane, reduce the skin resistance and cause skin allergies. Many people stop nursing after skin allergy, resulting in insufficient skin moisture and easy wrinkling, leading to a vicious circle. Therefore, whether it is cold or summer, allergic patients should take care of their skin very carefully. In addition to washing your face with warm water three times a day, you should also use some special skin care water and cream to refresh and moisturize your skin and persevere. In addition, we should keep enough sleep and necessary exercise and keep a good mood.

The second is desensitization by diet conditioning. Allergic patients should pay attention to a balanced diet and eat less greasy, sweet, irritating food, cigarettes, alcohol and so on. Some foods are also allergens, so we should pay attention to distinguish them. Eating more foods rich in vitamins can enhance the body's ability to deal with rabbit epidemic. Allergic patients can eat more foods with anti-allergic function to strengthen the skin's defense ability. According to nutritionists, onions and garlic contain anti-inflammatory compounds, which can prevent allergies. Other vegetables and fruits can also be allergic, among which broccoli and citrus are particularly effective. Because it is rich in vitamin C, and vitamin C is a natural antihistamine, if you take 1oo0 mg from your diet every day, it will be enough to prevent allergies. People with allergies have less free amino acids in their blood than healthy people. If the free amino acids in their blood can be increased, the incidence of allergies will be greatly reduced. This substance is the most abundant in soybean milk, and people with allergies had better drink some soybean milk every day.

The third is desensitization therapy. For some patients with severe symptoms, they can turn to medical means to change their allergic constitution. In this treatment, the doctor will chemically change the patient's serum to dilute it. Inject the changed allergen and antigen immersion liquid made of milk, pollen and other substances under the skin, and gradually increase the concentration of allergen to adjust the human immune system, so that allergic people can resist allergic substances, thus effectively preventing allergies. This therapy is more suitable for patients with type I allergy.
