You will be surprised to know that there are vast chemicals agents in environment. Some of chemical agents act as allergens to the skin. Skin allergy happens when these allergens join to carrier proteins in our skin and present them to the immune system of the skin and the body.
The main cause behind allergic reaction to some substance or food is the response of over-active immune system. Usually immune system acts as a protection, which protects our body against invading agents such as bacteria and viruses. But when it comes to allergic reaction the immune system start responding to a false alarm.
It has be found that substance that cause allergy have are different to each other. In some they are obvious as they encounter them daily in their routine life; some have them in relation to their occupation. Most are sensitive not to one but many numerous allergens. The allergy tests are suggestive to a certain extent only and since the cross reactivity between the common allergens is so much that if the test detects one or two there is a possibility that they might miss some more allergens to which a patient might be responsive. Therefore getting treatment is a good idea as it not only avoids the suspected allergens but also to stabilize the hyperactive skin cells.
Most common among skin allergy is house dust. This house dust mite not only cause allergic reaction in a few but also makes them prone to develop allergic reaction to numerous other allergens in the environment. Another unavoidable skin allergen is nickel. We will discuss mainly about nickel, which is now emerging as the most common cause of allergic contact dermatitis. Nickel is most common metal used by humans. As it is found in belts, buckles, watches, rings etc.
For personal accessories titanium is a great choice if you have multiple metal allergies or are unsure of the specific metal/alloy you are allergic to for example newer orthodontic wires and endovascular stents are now often made with titanium. Although extremely rare,
some individuals may react to the metals used in bio-medical devices such as nickel. Current data suggest a metal allergy may increase the risk of stent resternosis.
