Contact Allergy

A localised rash or irritation of the skin can be caused by contact with a foreign substance.

Contact allergies are commonly caused when skin comes into contact with items such as cosmetics, hair dye, chemicals, nickel and latex.

Symptoms of contact allergy can appear within minutes of exposure and fade away within minutes to hours or they can take anywhere from several days to weeks to heal.

In infants, symptoms typically appear on the face, arms and legs. In children 2 to 4 years, typically around the elbows, knees, ankles, head and neck. In adults, typically around the elbows, knees, ankles, wrists, hands and neck. If not treated properly scarring can occur.


Common symptoms include:

  • inflamed, dry, itchy skin
  • cracked, scaling or flaking skin
  • rashes
  • weeping lesions
  • swollen eyes, lips, tongue and throat (angioedema)
