There are actually two types of contact allergies.
Allergic contact dermatitis is a contact allergy in which an anchy skin condition does not show up for several hours after the skin has come in contact with a material to which the body is allergic. And, provided that the skin is not repeatedly exposed to the allergen, the rash settles down and might even disappear after a few days.
The other type of contact allergy is called urticaria. The rash usually appears within minutes of coming in contact with the responsible material, and may fade away within minutes or hours of the contact. One of the best examples of allergic contact urticaria is an allergic reaction to latex.
Agents that are most often the culprits of contact allergies are soaps, detergents, solvents, acids, and alkalis. But just plain water and friction can also be responsible.
Irritant contact dermatitis can actually affect anyone if they have had enough exposure to the irritant whether they are particularly allergic or not, but those with atopic dermatitis are especially sensitive. The hands are the area of the body most often affected by contact allergies.
The general term “allergy” is used to describe a condition in which a strong immune system reaction to a substance is exhibited with a minimum of exposure to a substance that is generally considered to be harmless to those who are not allergic to it.
When areas of the body other than the hands exhibit allergic contact symptoms, the culprit can often be very easily identified simply by the area where the rash occurs.
For example, a rash that develops on the wrist under a watch often indicates and allergic reaction to nickel. Itchiness may appear when placing on cheap costume jewelry such as earrings or rings. For people with metal sensitivities wearing gold jewelry always works best.
A rash that develops on the skin of the face usually means that Kaphon CG, which is a preservative in moisturizers, has caused the allergic reaction. Many over the counter products may contain ingredients that cause allergic flair ups. It is a wise practice to read labels before purchasing.
Fortunately there are many products on the market today that are hypoallergenic. Skin care products and make-up take the lead to accommodate allergy sensitive people.
Once you know you have an allergy then it is simple to find products that will suit your needs without having to end annoying symptoms.
