How to determine skin allergies?

1. Skin itching.

One of the most common symptoms of skin allergies is a sensation of itchiness, which can be itchy and sometimes painful. Allergic reactions can cause redness, red spots or patches on the skin.

2. Skin rash

Some allergic reactions can also cause a rash, which may appear as a rash, redness, small blisters or blisters on the skin.

3. Swelling and edema

Allergic reactions can also cause swelling and edema, especially in the face or other sensitive areas.

4. Dry or flaky skin.

Allergic reactions may cause the skin to lose moisture, resulting in dryness and flaking.

5. Pain or burning sensation

Some allergic reactions may also be accompanied by pain or burning sensations.

6. Other symptoms.

Severe allergic reactions may be accompanied by systemic symptoms such as difficulty breathing, swelling of the throat, dizziness, nausea, and vomiting.

If the above symptoms occur, it is recommended to consult a doctor for evaluation and diagnosis to determine whether it is a skin allergy and take appropriate treatment measures.

What are the causes of skin allergies?

1. Temperature changes.

When the temperature changes drastically, people with sensitive skin are prone to feel uncomfortable. The sudden changes in temperature can sometimes make their faces hot and red.

2. The changing of seasons.

When the seasons change, the surrounding natural environment will change. At this time, the pollen, spores and other allergenic substances in the air will increase, and then release histamine. This is a compound that is almost present in all tissues of the human body and can easily cause facial skin allergies.

3. Age Factor

As we age, the weakly acidic sebum membrane on the surface of the skin gradually becomes fragile, making it easier for allergens to invade the skin. So some people don’t have skin allergies when they are young, but after a few years, they will also have skin sensitivity.

4. Food can cause allergies.

People with allergies will have skin allergies after eating certain foods. Common allergenic foods include seafood, nuts, mangoes, etc.

5. Cosmetics cause allergies.

Most cosmetics sold on the market contain chemical ingredients such as alcohol, fragrances, preservatives, etc. to a greater or lesser extent, which are irritating to the skin to a certain extent, and cosmetics containing fruit acid are more likely to irritate sensitive skin.

6. Ultraviolet radiation

Women who love beauty will apply sunscreen to prevent ultraviolet rays from damaging their skin. In addition to causing skin aging and spots, ultraviolet rays can also cause skin allergies.

What to do if you have skin allergies?

1. Stay away from allergens

Stay away from allergens that cause skin allergies and prevent the skin from being irritated, so that the treatment will be effective.

Daily care:

Make sure your skin absorbs enough water to avoid dryness caused by heat.

Keep your skin clean and wash your face frequently with cold water to enhance skin resistance.

Take more vitamins A, C and E, which are good for the skin. This is true for healthy skin and even more important for sensitive skin.

For general sensitive skin, the first thing to do is to avoid further irritation, avoid eating spicy foods, and minimize facial steaming, massage, exfoliation, etc.

Keep warm and sun-proof, and protect your skin when going out.

2. Medication

Antihistamines, glucocorticoids, immunosuppressants, etc. can be selected according to the characteristics of the rash. The course of treatment generally varies from person to person.

Note: Different parts of the body and different rashes require different medications, and they need to be selected and used under the guidance of a doctor.

3. Physical methods

Cold compress: By lowering the temperature of the skin, it can narrow blood vessels and reduce the release of inflammatory mediators, thereby reducing redness, swelling and itching.

Phototherapy: Exposure to light of specific wavelengths and colors on the affected area can improve symptoms of skin allergies and regulate immune system function.

4. Desensitization treatment

Desensitization therapy is an immunotherapy method targeting specific allergens. By gradually increasing the exposure to allergens, the patient's immune system gradually adapts and reduces allergic reactions. This treatment method needs to be carried out for a long time and under the guidance of a professional doctor.
