The substance could be one of thousands of known allergens and irritants. Some of these substances may cause both irritant contact dermatitis and allergic contact dermatitis. Irritant contact dermatitis is the most common type.
This nonallergic skin reaction occurs when a substance damages your skin's outer protective layer. Some people react to strong irritants after a single exposure. Others may develop signs and symptoms after repeated exposures to even mild irritants. And some people develop a tolerance to the substance over time. Allergic contact dermatitis occurs when a substance to which you're sensitive allergen triggers an immune reaction in your skin.
It usually affects only the area that came into contact with the allergen. But it may be triggered by something that enters your body through foods, flavorings, medicine, or medical or dental procedures systemic contact dermatitis. You may become sensitized to a strong allergen such as poison ivy after a single exposure. Weaker allergens may require multiple exposures over several years to trigger an allergy. Once you develop an allergy to a substance, even a small amount of it can cause a reaction.
Children develop the condition from the usual offenders and also from exposure to diapers, baby wipes, sunscreens, clothing with snaps or dyes, and so on. Contact dermatitis can lead to an infection if you repeatedly scratch the affected area, causing it to become wet and oozing.
This creates a good place for bacteria or fungi to grow and may cause an infection. Most people are bothered by skin irritations at some point in time. These irritations are so common and varied that they are called by different names, which can lead to confusion. When an allergen is responsible for triggering an immune system response, the irritation is an allergic skin condition. There are several types of allergic skin conditions. Hives and Angioedema Urticaria is the medical term for hives, which are red, itchy, raised areas of the skin.
They can range in size and appear anywhere on your body. Most cases of hives are known as acute and go away within a few days or weeks, but some people suffer from chronic hives with symptoms that come and go for several months or years.
Your allergist may prescribe antihistamines to relieve your symptoms. If the cause can be identified, you should avoid that trigger.
However, the majority of chronic cases are not related to allergy. Routine testing, such as blood counts or allergy screens, are not recommended as they are unlikely to determine a cause and do not make a difference in treatment strategies. While related to hives, angioedema is swelling that affects the deeper layers of the skin.
It is usually not red or itchy and often involves the eyelids, lips, tongue, hands and feet. Angioedema commonly occurs with hives, but can occur on its own.
Food, drug or insect sting reactions are a common cause of acute hives and angioedema. Viral or bacterial infections can also trigger acute hives.
