What to do if facial skin is itchy?

Most of the itching on the face is caused by allergies, and it may also be caused by diseases such as dermatitis. Eat more light foods, don't wash your face with too hot water, be sure to remove makeup if you have it, keep your skin moisturized, and stay in a dry environment for a long time. When you are allergic, it is best to pay attention to what causes the allergy. Only by finding out the allergens can you effectively prevent allergies. If it is due to neurodermatitis, you are usually nervous or too excited, which will cause skin itching. In addition to paying more attention to maintenance, a good mood is also very important. Do more things that make you happy and try to relax yourself.

Causes of allergies

Main substances

The cause of skin allergies is that certain ingredients in cosmetics stimulate skin cells, causing them to produce antibodies, thus leading to allergies. The most common allergens in cosmetics are fragrances, preservatives and heavy metals. Among them, heavy metals mainly refer to some cosmetics that contain excessive amounts of lead and mercury, which have exfoliating and whitening properties. There are also hair dyes, paraphenylenediamine, cobalt chloride, oil paint nickel sulfate, and rosin. The spices mentioned here are not pure natural high-quality essential oils, but are generally inferior flavors or chemical flavors. However, after artificial fragrance adjustment, the smell is good, but the effect cannot be guaranteed. If people with genetically sensitive skin use cosmetics in a highly sensitive state, they are very likely to develop cosmetic contact dermatitis or aggravate the original disease.

main reason

If there is no quality problem with the cosmetics, but consumers still experience allergies after using them, there are mainly the following reasons: 1. Using cosmetics on top of existing dermatitis. 2. Cross-use several cosmetics. 3. Use inferior cosmetics. 4. Not using cosmetics correctly. The use of cosmetics with no quality issues causes cosmetic acne, cosmetic photosensitivity dermatitis and cosmetic skin pigmentation abnormalities, which are mainly related to improper selection of cosmetics by consumers. If people with oily skin choose water-in-oil cosmetics, it may lead to sebum excretion disorders and form blackheads and inflammatory papules, or secondary infection to form pustules.

Internal and external factors

1. Internal causes of allergies

1. The skin structure is damaged.

2. The skin's immune and protective functions decline.

Second, allergic external factors

1. Exposure to wind, cold, heat, spicy food, sunlight, excitement, scratching, pressure, seafood, cosmetics, bites, dust, pollen, cold water, etc.

2. Various counterfeit and inferior cosmetics or cosmetics that are not suitable for you.

3. After peeling with Chinese herbal medicine or chemical drugs.

4. Long-term application of hormone-containing ointments or cosmetics.

5. Oily skin or damaged skin after acne heals.

6. Age: Perhaps aging is an important reason for skin sensitivity. Some people's skin was not sensitive a few years ago, but has become sensitive in recent years. This is because there is a weakly acidic sebum film on the surface of young and healthy skin, which retains moisture and protects the skin from external damage. However, as we age, this sebum film is not as healthy as before, making it easy for some sensitive substances to invade the skin.

7. Pets: Sensitive skin can easily develop allergies due to the fur of domestic pets. The main cause of this pet allergy is the protein secreted by the oil glands on the bodies of cats and dogs. When pets lick their fur, these proteins are attached to the fur, then scattered into the air and attached to human skin.

8. Seasonal change: Due to various environmental factors, allergenic substances such as bacterial spores and pollen dispersed in the air will release a large amount of histamine, a compound that is distributed almost throughout all tissues of the human body, causing facial skin allergies.

9. Temperature changes: The temperature fluctuates between hot and cold, causing redness and hotness on the faces of sensitive people.

10. Ultraviolet rays: Ultraviolet rays can cause facial skin allergies.

11. Peculiar constitution.

Allergens

There are many allergens in spring. For people with allergies, any item can cause allergies.

May cause skin irritation. Our common allergens are:

Pollen: In spring, various flowers and plants bloom, and they release many pollen particles during this period. This is a major factor leading to the high incidence of spring allergies.

Dust mites: Dust mites grow in the dust around us, and the temperature and humidity in spring are just right for their growth and reproduction. Asthma patients and people with allergies will suffer asthma attacks if they inhale dust containing large numbers of mites.

Germs: It is easy to catch a cold in spring. Once a person’s resistance is low, viruses, bacteria, mycoplasma and other pathogens will be inhaled as allergens and directly induce asthma. Therefore, if you catch a cold repeatedly, your asthma attacks will continue, even one after another.

Climate: The temperature in spring is unstable, with a large temperature difference between day and night. Some people are allergic to the hot and cold air, which can trigger asthma attacks.

Common types

Neurodermatitis

Neurodermatitis is a common itchy skin disease in adults.

It is generally believed to be related to mental factors, such as emotional excitement, excessive work stress, sadness and anxiety, etc. Severe itching is the characteristic of this disease. The skin becomes thicker after scratching, but the boundaries are clear and there is no scale. It is light red in the early stage, and then there is local pigmentation, which often occurs around the neck, behind the elbows, buttocks and sides of the calves.

Peach Blossom Ringworm

It is a skin allergy reaction. Some light pink, round red spots will appear on the face. They will be itchy and a little peeling. Because it often occurs in the spring when flowers are blooming, it is called "peach blossom ringworm".

This skin disease begins in spring and subsides in summer and autumn. The main symptoms are whitish or reddish round or oval patches on the face with small scales attached to the surface, and sometimes itching. It is more common on the face, but can also be seen on the upper arms, neck, and shoulders. It is common in people with allergic constitution, and is also related to factors such as excessive exposure to wind and sun, indigestion, vitamin deficiency, dry skin, and the use of inferior cosmetics. Do not use medicine indiscriminately, otherwise it may aggravate the condition.

Seasonal skin sensitivity

Some people will experience more serious skin allergy problems when the seasons change: dryness, itching, peeling, erythema, etc. Skin sensitivity is related to dry skin, as well as to the environment, climate, age, food and cosmetics. People who are prone to allergies should pay more attention to the balanced intake of dietary nutrition, eat more fruits and vegetables, and less fish, shrimp, beef, mutton, greasy, sweet and irritating food.

Experts suggest that if allergic symptoms occur, you should immediately stop using any cosmetics and observe and care for your skin. During this period, do not wash your face with too hot water to avoid irritating the skin, and pay attention to sun protection.

Treatment and prevention

Streamline maintenance steps: suspend unnecessary maintenance and maintain basic

Just three steps. When your skin shows signs of allergy, you should immediately reduce the number of maintenance steps. Providing the skin with the most fundamental moisturizing and soothing, and reducing the maintenance steps to a minimum, can promote the development of the skin's own immunity and restore healthy skin.

Avoid irritating skin care products: Avoid using irritating products such as fruit acid, exfoliating, and alcohol-based lotions. Exfoliating products like scrubs and deep cleansing masks all work by enhancing the metabolism of the stratum corneum. They are too irritating for sensitive skin. In addition, cleansing actions that require repeated scrubbing should be shortened to 30 seconds.

Replace essence with cream: Use cream texture to buffer the irritation of essence. The maintenance ingredients in the essence are of a relatively pure concentration, and the liquid texture has strong penetrating power, so it is more irritating to the skin. Cream is like the airbag in a car, which can protect the skin from direct impact and reduce irritation. If people with sensitive skin want to try high-concentration whitening essence, it is recommended to mix it with moisturizing cream before applying it, which will be gentler on the challenge of skin tolerance.

If you are allergic, you should choose a herbal skin care cream with anti-inflammatory and soothing effects, and use it after washing your face with clean water. If the skin continues to become red, go to the hospital for desensitization treatment or choose this type of cosmeceuticals and skin care products.

Take good care of your skin daily. Regardless of the cold or hot season, spring or autumn, patients with allergies must be very careful to take care of their skin. In addition to washing their faces with warm water twice a day, they must also use some special skin lotions, skin creams, toners, and moisturizers persistently.

You should get enough sleep, essential exercise, and keep a good mood.

For some patients with severe symptoms, medical means can be sought to change the allergic constitution. In this therapy, doctors use chemical methods to change the patient's serum, dilute it, and inject the changed allergens and antigen extract made of milk, pollen and other substances subcutaneously. They also gradually increase the concentration of allergens to adjust the human immune system and enable the allergic person to develop resistance to allergens, thereby effectively preventing allergies.

Preventive maintenance

In the bright spring, when pollen, catkins, dust mites and dry wind blow on our bodies, many people with allergies have no time to appreciate the beautiful scenery. As the temperature rises, the human body's sebaceous glands secrete more vigorously. Coupled with the strong wind outdoors, various allergic factors dance in the air, which can easily cause skin itching and acne.
