Itchy skin on face and neck

When there is any itching problem on the face, everyone will be inexplicably worried, because the facial skin is very important. One of the biggest concerns of everyone is that the itching problem will leave scars on their face. Since the face and neck are connected, itching on the face often causes itching on the neck as well. So what could be the cause of itchy skin on the face and neck?

Allergic dermatitis is a skin disease caused by allergens. It mainly refers to skin symptoms such as redness, itching, wheals, and peeling caused by the human body's contact with certain allergens. Specific allergens can be divided into four categories: contact allergens, inhaled allergens, ingested allergens and injected allergens. Each type of allergen can cause a corresponding allergic reaction, the main manifestations of which are various dermatitis, eczema, and urticaria. To prevent and treat allergic dermatitis, pay attention to diet conditioning, balanced nutrition, eat more fruits, vegetables and other vitamin-rich foods. Vitamin C is a natural antihistamine and should be consumed from the diet every day.

General principles of prevention: Find the cause and eliminate and avoid it as much as possible.

1) Reduce the factors that induce aggravation and irritation, such as mechanical factors (scratching, friction); physical and chemical factors (hot water washing, high temperature, low humidity, irritating drugs); biological factors (animals, plants, microbial infections, etc.); mental stress or depression or digestive dysfunction.

2) Stay away from allergenic factors and reduce allergens in the environment as much as possible, such as inhaled allergens (any substance that can be inhaled through the respiratory tract is a potential allergen), including dust, dust mites, cotton wool, pollen (spring, summer and autumn), animal hair, fungi, insects and smoke. Food allergens (allergens that cause allergic reactions when ingested) include fish, shrimp, crab, beef, mutton, eggs, milk, peanuts, soybeans and nuts. Contact allergens include clothing, dyes, cosmetics, jewelry, topical medications, paint glue, organic solvents, hair dyes and disinfectants. To create a healthy and hygienic environment, always keep the indoor environment clean, open windows for ventilation, maintain appropriate temperature and humidity, and do not use disinfectants casually; try to minimize children's exposure to pollen in spring; avoid direct sunlight in summer; do not keep pets at home, especially not indoors; use less carpets and vacuum frequently; do not use electric blankets; avoid irritating cosmetics, etc.

3 ) Take care of your skin, take a bath scientifically and reasonably, choose a soap with a neutral pH and no irritation; do not use skin care products indiscriminately, choose soft cotton fabrics for underwear, and do not wear wool or chemical fiber fabrics, as these fabrics are rough and irritating to the skin.

4) Pay attention to diet conditioning, balanced nutrition, eat more fruits, vegetables and other vitamin-rich foods. Vitamin C is a natural antihistamine and should be consumed from the diet every day. Eat less fish, shrimp, beef, mutton, greasy, sweet and spicy food.
