Skin suddenly becomes itchy and red?

In daily life, we often suddenly experience itchy skin and a large red patch. Most of the causes of this phenomenon are caused by allergies. You can use chlorpheniramine and oral vitamin C to relieve the symptoms of itching. Then we must eat a light diet, keep our skin clean, and develop good living habits. If it does not get better, it is best to see a doctor in time to find out the cause and treat it symptomatically.

What to do if you have skin allergies

Once the skin becomes sensitive, it will become very fragile and even the slightest changes in the external environment may cause skin allergies. Therefore, you must pay attention to careful care in your daily maintenance.

1. Keep your skin clean. Spring is windy and dusty. The dust mixed with the abundant sebum secretion can easily cause rough skin. Therefore, you should always keep your skin clean. You can use mild facial cleanser and lotion to help kill bacteria, clean and soften the skin.

2. Do not change the cosmetic brands you are used to at will, because the skin needs to adapt to the new climate and is in a period when its ability to resist and adapt to the external environment is relatively weak. If you change brands at will, allergies are likely to occur.

3. Pay attention to skin moisturizing at all times and enhance skin resistance. You can choose refreshing and hydrophilic skin care products. Skin care products with high oil content should be used as little as possible in winter.

4. Pay attention to the impact of wind and sand on the skin. People with sensitive skin should pay special attention to using scarves, masks, etc. to cover themselves when going out to avoid being blown by the wind.

5. Eat more fresh fruits and vegetables, and less irritating foods that may easily cause allergic reactions, such as seafood, bamboo shoots, etc.

Five taboos for emergency treatment of skin allergies

1. Avoid excessive scratching

Many people with skin allergies will have itching symptoms. People with itchy skin always want to scratch, but it should be noted that it is best not to scratch the skin when allergic. Although this may give temporary relief, it will aggravate the skin disease. When you have an allergy, scratching your skin often makes it itchier. If you have acute eczema, scratching the skin will cause it to spread, so when you are allergic, you must control your hands and not scratch.

2. Do not use hot water

Many people will use hot water to relieve the discomfort when they are allergic and itchy. This method can relieve the itching temporarily, but the itching symptoms will become more severe afterwards, especially dermatitis symptoms such as acute eczema. Because after the skin is scalded by hot water, the permeability of capillaries increases, some allergic substances will be released in large quantities, making the penetration and erosion more serious and worsening the condition.

3. Do not use alkaline detergents

Some patients with chapped hand eczema like to repeatedly use alkaline detergents such as alkaline soap, washing powder, and detergent to wash their hands. This method is incorrect. Using alkaline detergents for washing will make the skin drier and aggravate the symptoms of chapped and itchy skin. Washing with soap will also reduce the oil content of the skin, causing dry skin and making itching worse.

4. Don’t eat anything you want

Some people often suffer from frequent skin allergies because of their habit of eating indiscriminately. For example, they often eat fish, shrimp, crab, mutton, beef, irritating foods, pepper, chili, garlic, leek, etc. These foods are very easy to cause allergic skin diseases such as eczema and urticaria. If you still eat the above foods when you have these symptoms, the symptoms will worsen.

5. Do not abuse medication

When suffering from skin allergies, drug abuse is a common problem for many patients, and this practice can also aggravate the symptoms. For example, using topical corticosteroids to treat tinea manuum can actually cause the rash to spread. For patients with facial seborrheic dermatitis, if they frequently use topical hormones, it is easy to cause difficult-to-cure hormone-dependent dermatitis, acute erosive exudative eczema and other diseases.
