Itchy and peeling facial skin

The facial skin is very important to everyone. If there is any problem with the facial skin, it will have a great impact on one's image. If facial skin becomes itchy and peeling, it may be caused by skin allergies. In this case, you should go to a ventilated place immediately and wash your face with warm water.

Facial skin allergy is a very common form of allergy, with 20% of people suffering from skin allergies. The symptoms of skin allergy are itching, which may also be accompanied by redness, swelling, dry scales, blisters or scabs and exudate from the lesions. Occasionally, symptoms such as facial tightness, numbness, and swelling may occur.

Causes of allergies

The main 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.

If there is no quality problem with the cosmetics, but consumers still experience allergies after using them, there are mainly the following reasons:

1. Use cosmetics on the basis of existing skin inflammation.

2. Use several cosmetics interchangeably.

3. Use inferior cosmetics.

4. Failure to use 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 face of sensitive people.

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

11. Peculiar constitution.

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

May cause skin irritation. Our common allergens include: Pollen: In spring, various flowers and plants bloom, and they release a lot of pollen particles during this period, which 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.
