Skin allergies

Skin allergies occur when your immune system overreacts to a harmless substance, leading to inflammation, itching, redness, or hives. Common triggers include metals (like nickel), fragrances, latex, plants, foods, and medications. 

Common Types

  • Contact Dermatitis: An itchy rash triggered by direct contact with an allergen (e.g., jewelry, soaps, poison ivy).

At-Home Relief

  • Avoid Triggers: Stop using suspected soaps, lotions, or new jewelry. Keep a symptom diary to track exposures.
  • Cool Compresses: Apply a damp, cool cloth to itchy areas to soothe inflammation.
  • Moisturize: Apply hypoallergenic fragrance-free moisturizer daily to lock in moisture and repair your skin barrier.
  • Avoid Scratching: Scratching worsens inflammation and can lead to skin infections. 

When to See a Doctor

While many minor allergic rashes can be managed at home or treated with over-the-counter antihistamines or hydrocortisone creams, you should seek medical attention if: 

  • The rash spreads rapidly or covers a large area of your body.
  • You develop a fever.
  • Blisters begin to weep pus (signs of infection).
  • You experience swelling of the face, lips, or tongue, or have difficulty breathing, which can indicate a severe, life-threatening reaction (anaphylaxis). 

To pinpoint exactly what is causing your reaction, you can consult a board-certified allergist or dermatologist who can perform patch tests or blood tests. Read more about triggers and testing on the
