Skin allergies are caused by a variety of symptoms. These allergies are triggered when a foreign substance (allergen) encounters the skin. Skin allergies can occur anywhere on the body, and symptoms range from mild to severe, depending on the type of skin allergy. When the allergen enters the body, the immune system creates antibodies to fight against it, causing the skin to break out and become irritated.

Common Allergens that trigger a skin allergy

  • Sunlight
  • Pollen
  • Latex
  • Certain foods
  • Insects
  • Poison ivy

Types of Skin Allergies

  • Hives: Also called urticaria, these are rashes on the skin from an inflamed immune system, releasing histamine, a compound that is triggered by allergies. Hives cause blood vessels to leak, leading to the common itchiness and swelling of the skin.
  • Hives can be treated by applying a cold compress to soothe the skin. Wear loose clothing that is not denim or wool that irritates the skin. If symptoms worsen, get a prescription to treat the hives or try OTC antihistamines.
  • Eczema: A well-known skin condition, especially among children, caused by leakiness of the skin barrier. This triggers itchy, dry bumps and rashes on the skin because of certain environmental factors or food. Eczema is also linked with asthma, hay fever, or food allergy.
  • The best way to treat eczema is to moisturize the skin with medicated products. Brands such as CeraVe, Eucerin and Vanicream.
  • Angioedema: Swelling that is deep within the skin, that does not cause itchy, is caused by certain medications or food. Acute angioedema is when the condition is short, ranging from minutes to days, usually triggered by medications or food. Chronic angioedema is when the condition reoccurs or stays for an extended period; the cause, however, is unknown.
  • To treat acute angioedema, apply a cold compress to the skin. Seek professional help when symptoms worsen or last for an extended period.
