Contact Dermatitis

can be caused be either an allergic reaction to a material (allergic contact dermatitis) or by irritants, such as harsh chemicals or excessive exposure to water (irritant contact dermatitis). Allergic contact dermatitis is an itchy skin condition that is caused by an allergic reaction to any material that comes in contact with the skin. The affected skin may be red, swollen, blistered, dry, and bumpy. Allergic reactions may vary from one person to another. An allergy can develop at any point in a person’s lifetime. Some common sources of allergies develop from toiletries, cosmetic products, rubber products, medications, and metals. When allergic contact dermatitis is suspected, patch testing can be performed. This diagnostic testing consists of a series of applications applied to the patient’s skin to find out whether their skin condition may be caused or aggravated by contact allergy.
