Contact Dermatitis – An Overview
Contact dermatitis is an itchy rash that occurs when skin comes in contact with irritable substances. It leads to a skin allergy as the protective skin layer gets damaged. Though not contagious, this rash can be irritating.
Contact dermatitis Causes
Contact dermatitis is caused by certain allergens and irritants. When the skin comes in contact with these allergens it causes allergic reaction and irritation.
The three types of contact dermatitis include: allergic contact dermatitis, irritant contact dermatitis and photo contact dermatitis.
Allergic contact dermatitis
It occurs when the skin comes in contact with allergens, causing allergic reactions. Causes of allergic contact dermatitis are poison oak, mango, latex gloves, jewelry, perfumes or skin care products.
Irritant contact dermatitis
It occurs when the protective layer of the skin gets damaged. It is the most common type of dermatitis. Causes of irritant contact dermatitis include wool dust or saw dust, soaps, deodorants, bleach, solvents and rubbing of alcohol.
Photo contact dermatitis
It occurs when the irritants get activated due to the exposure of sunlight.

Contact dermatitis Diagnosis
The doctor may diagnose contact dermatitis by identifying the cause through a physical examination and evaluating the medical history. The doctor may also recommend a patch test in case of severe allergy. It helps in determining the intensity of skin allergy as well as the reaction to it.
