My face turns red and allergic when I change seasons.

This is seasonal allergy. Every time the climate changes, the temperature difference is large or the season is warm and humid, many people often have skin allergies. Due to various environmental factors, allergens such as bacterial spores and pollen scattered in the air will release a lot of histamine, which is a compound distributed in almost all tissues of human body, causing symptoms such as stuffy nose, sneezing, runny nose, itchy throat and swollen eyelids. It causes people's skin itching, rashes and scales, peeling, different red and white faces, multi-colors and other allergies.

Preventive measures of seasonal allergy

● In terms of diet, pay attention to balanced nutrition and eat more milk, freshwater fish, bean products and fresh vegetables and fruits to enhance skin resistance. Avoid eating salty fish, shrimp, crabs and other foods that are easy to cause allergies.

● People who are usually allergic should be very cautious when using cosmetics for the first time. Skin patch test should be done in advance. If there is no response, they can use it, otherwise they can't. Cosmetics can't be changed frequently, and skin care products containing too much perfume and too much acid and alkali can't be used. High-grade cosmetics contain complex chemical components and spices, so there are more sensitization opportunities.

● It is wrong to care too much and ignore allergies. Too many products and too complicated skin care procedures are not effective ways to improve allergies. But you can't apply nothing, because insufficient water may lead to more serious peeling, and insufficient sun protection may make the skin rough and cause uneven pigment.

● If you find yourself sensitive to cosmetics, stop using it, and don't make your skin worse because of greed. If you must make up, you can use the key makeup method, draw eyeliner, apply some mascara, and then apply natural glossy lipstick, which can also create a very beautiful makeup.

● Do not wash your face with too hot water after skin allergy, so as not to irritate your skin, and do not use soap. The alkali in it will aggravate the symptoms of skin allergy. Wash your face with mild facial cleanser, without any skin care products, and gently massage your face with your fingers (it is best to pat it with your fingers to avoid dermatitis caused by excessive force), thus relaxing facial muscles, promoting normal blood circulation and accelerating the recovery of skin allergies. You can also try the following first-aid tips, such as applying ice cubes to a red and hot area, taking milk out of the refrigerator, adding water to stir, and applying a clean cloth to the affected area, which can reduce the risk of inflammation.
