L24: Irritant contact dermatitis

Irritant contact dermatitis is a type of skin condition that results from direct contact with harmful substances. Physical or chemical irritants like detergents, soaps, disinfectants, and industrial chemicals can trigger this condition. Exposure to these substances causes damage to the outer layer of skin leading to symptoms such as redness, itching, burning sensation, blisters, and dry, cracked skin. The symptoms usually appear only on the body part that came into contact with the irritant. Factors such as the intensity of exposure, duration, and an individual's skin sensitivity dictate the severity of the condition. Constant exposure can lead to chronic dermatitis where the skin becomes thick, leathery, and dark. Irritant contact dermatitis is not contagious as it is a response of an individual's skin to an irritating substance. It can affect any body area but is most commonly seen on hands and face.
