Allergic Contact Dermatitis
The allergic contact dermatitis is a delayed sensitive reaction which happens when a person comes in contact with a specific allergen to which a specific sensitivity has been developed.

The most recent allergens include nickel, rubber chemicals, chromates, and certain topical creams and ointment. Likewise, sensitizers may include formaldehyde, lanolin, and fragrance.
