What Causes the Appearance of Small Red Pimples on the Skin?

Small red pimples on the body may be caused by urticaria, eczema, allergies, insect bites, and other reasons. If you feel discomfort, it is recommended to seek medical attention promptly.

1. Urticaria

Urticaria may cause red pimples on the body, accompanied by sudden redness, swelling, and itching of the skin, as well as various shaped rashes. If the condition becomes increasingly severe, the rashes will gradually expand and merge into one. Most of these will resolve spontaneously within 24 hours, but new rashes may appear.

2. Eczema

Eczema is an inflammation of the epidermis and superficial dermis caused by various factors. Red pimples may appear on the patient's body, accompanied by redness, erosion, and even effusion. The symptoms of eczema are usually distributed mainly on the limbs, but they may also occur on the face or trunk.

3. Allergy

Allergic reactions can be caused by contact with allergens on the skin or mucosa, inhalation, ingestion, or injection of allergens. Skin rashes often occur on the face, neck, and upper limbs. They are generally painless but may cause intense itching and resolve slowly.

4. Insect Bites

In summer, there are many insects, and it is easy to be bitten by them outdoors. Bites from fleas, mites, bedbugs, and other insects may cause allergic reactions, resulting in red spots, wheals, papules, or ecchymoses on the skin, accompanied by intense itching. Infants and young children may develop angioedema after being bitten, with exposed areas such as the foreskin, back of the hand, and face being particularly susceptible.

1. Eliminate Allergens

Firstly, it is important to eliminate allergens by discontinuing the use of irritating cosmetics or skincare products. After washing your face with clean water, choose skincare products with calming and anti-inflammatory effects. Pay attention to your diet and avoid insect bites. If there is persistent redness, seek medical treatment at a hospital.

2. Avoid Self-medication

Do not take medication without consulting a doctor and avoid purchasing drugs from pharmacies. Although drugs may temporarily suppress inflammation, long-term use may cause side effects. It is recommended to undergo a detailed examination and targeted treatment at a formal hospital to clarify the cause of the red pimples and receive effective treatment.

3. Daily Care

Enhance your resistance and skin defense by maintaining adequate sleep and a balanced diet. Consume foods that are beneficial to your health and avoid spicy and greasy foods. Stay away from polluted environments and places that are prone to allergies to reduce skin irritation.
