Irritated skin can be caused by a variety of factors. These include immune system disorders, medications and infections. When an allergen is responsible for triggering an immune system response, then it is an allergic skin condition.

Q1 What Are Common Skin Allergies? Bumps, itching, redness and other skin conditions are very common, and their cause may not be easily identifiable. Rashes can be caused by many things, including plants (poison ivy, for example), allergic reactions to a medication or a food, or an illness (measles or chickenpox, for example). Eczema and hives, both of which are related to allergies, are two of the most common skin rashes.

Atopic dermatitis

Atopic dermatitis is the most common form of eczema, affecting between 10 and 20 percent of children and 1 to 3 percent of adults. A common symptom of atopic dermatitis is dry, red, irritated and itchy skin. Sometimes, especially when infected, the skin may have small, fluid-filled bumps that ooze a clear or yellowish liquid. People with atopic dermatitis often have a family history of allergies.

Hives

Hives (urticaria) are red bumps or welts that appear on the body. The condition is called acute urticaria if it lasts for no more than six weeks, and chronic urticaria if it persists beyond six weeks. Acute urticaria is most commonly caused by exposure to an allergen or by an infection. The cause of chronic urticaria is largely unknown.

Contact dermatitis

Contact dermatitis is a reaction that appears when the skin comes in contact with an irritant or an allergen. Symptoms can include a rash, blisters, itching and burning.

Soaps, laundry detergents, fabric softeners, shampoos — or even excessive exposure to water — can all cause contact dermatitis. Other items that can cause a reaction are metals (such as nickel, a component of stainless steel and other alloys used to make costume jewelry), adhesives, nail polish, topical medications, plants and latex gloves.

Sometimes an allergen won’t cause a skin reaction unless the skin is also exposed to sunlight. This condition is called photo allergic contact dermatitis. It can occur with products such as shaving lotion, sunscreen and some perfumes.

Latex allergy

Latex allergy usually develops after repeated exposure to latex products, including balloons or medical gloves. Symptoms may include hives, itching or a stuffy or runny nose. Some people may experience asthma symptoms, such as wheezing, chest tightness and difficulty breathing.

Allergic reactions to latex are less common now, since many hospitals and health care workers have switched to non-latex gloves or low-protein latex gloves.
