Contact dermatitis

Also called Contact eczema, Irritant dermatitis, or Allergic contact dermatitis

Contact dermatitis is a type of eczema caused by contact with a particular substance. Irritants such as soaps, detergents and solvents can damage the skin directly, while allergens such as nickel, fragrances, hair dye or rubber can cause an allergic reaction. The rash usually appears where the substance touched the skin.

What it is

It is common in jobs where hands are often wet or in contact with chemicals, such as hairdressing, cleaning and healthcare.

Avoiding the trigger is the most important step. Emollients and steroid creams help the skin heal. Patch testing can identify an allergy.

Common signs

  • Red, itchy, dry or cracked skin
  • Blisters or weeping skin
  • A burning or stinging feeling
  • A rash in the area that touched the substance

How it is usually diagnosed

  • Questions about exposures at home and work
  • Patch testing by a dermatologist

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Notes about work exposures
  • Treatments that helped

Questions to ask your doctor

  • What is causing it?
  • Should I have patch testing?
  • How do I protect my skin at work?

When to get help right away
