  4 minutes

Many people get rashes that are itchy and irritating. It is possible that your rash could be eczema. Eczema occurs because of many different reasons. There are also various types of eczema. Today, however, we will focus on allergic eczema, which is also known as contact dermatitis.

What is allergic eczema?

Allergic eczema refers to the skin condition that occurs when you are in contact with something you might be allergic to. Like eczema, it causes a rash that can be itchy, red and inflamed. Sometimes it can even cause blisters. This kind of eczema can turn painful if you don’t treat it immediately.

What are the symptoms of allergic eczema?

This kind of eczema causes an allergic reaction to your skin. Therefore, it can cause the following symptoms.

  1. Rashes around the area that has come in contact with the allergen.

2. Redness of the skin.

3. Swelling of the skin exposed.

4. Very often, these rashes are itchy, but you should avoid scratching them.

5. You can also have a burning sensation around the rashes.

6. If left untreated, the rash can turn into a painful blister or develop an infection.

When does allergic eczema occur?

This condition can occur any time after the skin has come in contact with an allergen. Quite often, the symptoms appear only 48 to 96 hours after exposure! So it is possible that you could be exposed several days before you can see a physical reaction. If you are looking for what might have caused the allergy, you may have to retrace your steps many days earlier.

Common allergens that cause allergic eczema

There are various things that can cause an allergic reaction to the skin. Technically you can be allergic to anything. But let us discuss the top 10 common allergens that cause this skin condition.

1. Certain oils and scents used in perfumes can cause irritations and allergic reaction in people. Fragrances used in skincare products can also be the reason for an allergy.

2. Ointments used for anti-bacterial purposes or antifungal creams like methylisothiazolinone and neomycin can result in allergic reactions in some people.

3. Formaldehyde is a preservative used in products that can cause allergies in people.

4. Many people are allergic to hair dyes. This is because of an ingredient known as paraphenylenediamine.

5. Many metals like nickel, cobalt and chromium can also cause allergic reactions. They are used to make jewellery that you wear.

6. Clothing dyes can also cause reactions when you wear the clothes and the colour bleeds.

7. Latex allergies are pretty common and can cause allergic eczema.

8. Poison ivy can definitely cause a skin allergy in someone who might not be allergic too.

9. Adhesives used in household items are a common cause of allergies.

10.  Chemicals in cleaning products, soaps and detergents are common allergens.

How do you know you have allergic eczema?

Step 1 and the most important thing to do is visit a doctor, skin specialist or dermatologist. The doctor will examine your skin and do further tests if allergic eczema is suspected. They will try to find out what you are allergic to.

  • A patch test is when various patches with allergens are stuck to your back. They stay on for 48 hours, after which you are checked for reactions and allergies.
  • One way to test for allergies is to do a blood allergy test. It is a blood test where they check how your blood reacts to different allergens. This test can be expensive and not always conclusive.
  • You can also test for allergies with a skin test. This is a slightly painful one where they prick your skin with different allergens on your arm and wait for a stipulated amount of time for reactions.
  • If these allergy tests cannot ascertain what you are allergic to, your doctor might consider a skin lesion biopsy. This entails extracting a small part of the skin with an allergic reaction and sending it for testing to a lab.
