Overview
Allergic contact dermatitis is an inflammation of the skin caused by an allergy to a substance (the allergen). Unlike irritant dermatitis, which occurs at the time of the allergen touching the skin, contact dermatitis occurs 48–72 hours after exposure. The initial exposure does not cause the rash, but it sensitizes the skin to the next exposure.

The most frequent triggers causing allergic contact dermatitis include:
  • Perfumes, nickel, neomycin, formaldehyde, lanolin, and other chemicals common in the environment.
  • Poison ivy, poison oak, and poison sumac.
