What is an allergy?

An allergy occurs when the body reacts to an external substance. This may be something that is eaten, inhaled or that comes into contact with the skin. Many allergies only develop following repeated exposure the same substance – hence it is possible to become allergic to something that you have been regularly exposed to in the past, especially in relation to skin contact allergies.

What are the types of allergy?

There are two main types of allergy in relation to skin disorders. The first is immediate (or type I) allergy. Here, an immediate reaction occurs when coming into contact with the causative agent. This usually results in hives, but can also lead to swelling wheezing, feeling faint and difficulties in breathing. An example of this form of allergy is peanut or latex allergy.

The second type of allergy is delayed (or type IV) allergy. This is very different as the reaction can take several hours or days to develop and usually causes a rash that is itchy and scaly, much like eczema. The rash can be very red and swollen as well. Common causes of delayed allergy included hair dye, fragrances and preservatives.

This is because most of the chemicals (except fragrances) are washed out of the clothing. It is best to use a fragrance-free washing powder if you are known to be allergic to fragrances.
