Contact Allergy

Contact allergy is a type of skin rash that occurs when a substance that irritates the skin touches it constantly. A substance that may be completely harmless to some may lead to an allergic skin reaction in others.

The most common manifestation of contact allergy is an itchy rash.The affected area first becomes itchy, then red and swollen with vesicles (water bubbles). Although usually confined to the area of
contact, the rash can spread to other parts of the body. Occasionally the rash is more chronic, manifesting as an itchy patch that does not heal for weeks or even months. This usually occurs when there is frequent contact with the substance.
