Beware of these three types of skin allergies.
1, seasonal skin sensitivity
Main symptoms: itchy skin, peeling, erythema and itching all over the body, especially in limbs.
Some people have serious skin allergy problems every season: dryness, peeling, erythema, itching and so on. Skin sensitivity is related to dry skin, as well as environment, climate, age, food and cosmetics. Allergic people should pay more attention to the balanced intake of diet and nutrition, eat more fruits and vegetables, and eat less fish, shrimp, beef and mutton, greasy, sweet and irritating food.
2. Cosmetic allergy
Main symptoms: aggravated skin allergy, rough skin and pigmentation, which mostly appear on the face with cosmetics.
Stop using any cosmetics immediately after allergic symptoms appear, and observe and maintain the skin. At the same time, don't wash your face with too hot water, so as not to irritate your skin and pay attention to sun protection.
Some ingredients in cosmetics can cause skin allergy, stimulate skin cells and make skin cells produce antibodies, thus causing allergies. If it is skin allergy caused by improper use of cosmetics, you can't treat common skin diseases with ointment at will, otherwise it will cause rough skin, pigmentation and aggravate skin diseases.
3. Neurodermatitis
Main symptoms: strange itching, mostly around the neck, behind the elbow, buttocks and calf side.
Neurodermatitis is a common pruritic skin disease in adults. It is generally believed that the pathogenesis is related to mental factors, such as emotional excitement, overwork and anxiety. Severe itching is the characteristic of this disease. After scratching, the skin thickens, but the boundary is clear and there is no scale. It is reddish at the initial stage, and then there is local pigmentation, which is easy to occur around the neck, behind the elbow, buttocks and calf side.
So, can skin allergies be contagious?
In fact, skin allergies are not contagious. There are many reasons for allergies, including cosmetics, chemicals, pollen, certain foods, polluted air and so on.
Skin allergy, also known as sensitive skin, is a very common form of allergy, and 20% people have skin allergy. Skin allergy mainly refers to the abnormal phenomena such as redness, itching, peeling and allergic dermatitis when the skin is stimulated by various kinds. Seriously affect the patient's face.
What should I do if my skin is allergic?
Avoid all kinds of sensitive and irritating foods.
Such as fish and shrimp, coffee, wine and strong tea. Professor Ye Shitai, the founder of China's allergy discipline, once summed up four words: avoid (that is, avoid contact with substances that cause allergies), avoid (don't contact or eat substances that cause allergies), replace (find other substances to replace things that cause allergies), and move (away from the environment that causes allergies).
Excessive scrubbing, severe scratching, to avoid hot water burns and other external stimuli.
Many patients repeatedly wash themselves with hot water after allergies, and some even wash themselves with salt water and pepper, or simply scratch their blood. Although these measures are effective in a short time, once they stop, they will become more and more itchy. Moreover, the above actions or methods only convert itching stimulation into pain stimulation, which eventually leads to local skin hyperplasia, hypertrophy and infiltration, and changes in nutrition will aggravate itching; Such a vicious circle is bound to aggravate skin diseases.
