Hand Dermatitis

Hand dermatitis is a skin condition of varying severity, and most often caused by a combination of factors. While it most commonly affects the hands, it can affect other areas of the body in long standing cases. The condition consists initially of skin in the affected area become red and dry. Initial reactions are generally mild and only intermittent. This will progress into the development of itchy bumps and blisters. This may also be accompanied by scaling, weeping, swelling, and cracking of the affected area. In persistent cases, secondary bacterial infections may develop, and the condition may spread to the forearms or feet.

Hand Dermatitis can affect anyone, and is caused by a number of determining factors, including constitutional factors, injury, and allergy. Constitutional factors include genetics (those with a family history of dermatitis, asthma, and/or hayfever), a personal history of other skin conditions (such as psoriasis), and even increased emotional stress. Injury factors generally refer to frequent contact with skin irritants, most commonly frequent water immersion in combination with detergents (soap, shampoos, etc.) and solvents (turpentine). Friction and repetitive exposure to these irritants leads to a worsening of the condition, with even a brief exposure causing a months-long flaring of the condition. Allergy factors refer primarily to specific hypersensitivity to a common substance, including certain metals, fragrances, rubber, and hair dye.
