Skin Allergy Definition, Causes and Symptoms

What is a skin allergy? A skin allergy is a reaction caused by a substance that comes in contact with the skin, thus a skin allergy. Some types of contact skin allergies are dermatitis, eczema and hives. Contact dermatitis develops when the skin comes in contact with something that a person is allergic to. A reaction to skin allergies may cause a redness or even swelling, stinging, burning or blisters and yes, itching.

Skin Allergies are one of the most prevalent causes of skin conditions. Generally, they are caused by an immune system which becomes hypersensitive after exposure to certain substances which it recognizes as harmful. As a result of this exposure, the body's immune system releases huge amounts of antibodies to combat these "supposedly" harmful substances. The release of these immune cells may then cause an adverse reaction in other cells within the body.

The major symptom of skin allergy are hives, rashes, swelling, itching which may includes one or more physical signs like dry skin and it results in cracking of the skin. The hands, face, arms and neck are the common areas affected by skin allergies as are exposed usually every day.

Animal dander (particularly from cats), pollen, dust mites and certain medications can all be causes of allergies. Some individuals are also allergic to certain foods or even whole food groups.

Something to keep in mind with the skin reaction as a result of food allergies is that irritating the area or becoming stressed over the issue can cause the skin reaction to be more pronounced. In other words if you become stressed you can actually psychologically induce hives. It is a reaction of too much chemical in your body as a result of stress. This means that for those with a food allergy they can cause the hives to become worse than they would normally be.
