Skin allergies occur when the immune system reacts to a substance that is normally harmless to the body. These substances, known as allergens, can cause a range of symptoms on the skin, including itching, redness, and swelling. There are many different types of skin allergies, with different causes and symptoms.
Contact dermatitis: This type of allergy occurs when the skin comes into contact with a substance that causes an allergic reaction. Common allergens include soaps, detergents, cosmetics, and metals like nickel.
Hives: Hives are raised, itchy bumps on the skin that can be caused by an allergic reaction to a food, medication, or another allergen.
Angioedema: Angioedema is a type of swelling that occurs beneath the skin’s surface. It can be caused by an allergic reaction to foods, medications, or insect bites.
Allergic contact urticaria: This type of allergy occurs when the skin comes into contact with an allergen, causing a localized rash.
Treatment for skin allergies depends on the type and severity of the allergy. In many cases, avoiding the allergen is the best approach. In other cases, medications like antihistamines, corticosteroids, or immunosuppressants may be prescribed to relieve symptoms.
Preventing skin allergies involves identifying and avoiding potential allergens. This can include reading labels carefully and using hypoallergenic.
