Skin Allergies - Cause and Treatment

Causes of skin allergies

When the skin cannot tolerate certain substances, it reacts to their presence: this reaction can be either in the form of eczema or in the form of hives, this results in itching and redness of the skin.

It is often difficult to pinpoint the cause of the allergy. It could be something you've ingested (foods, medicines, drinks) or something you've applied (cosmetics, antiseptics) or something you have worn (clothes, jewellery) or sometimes even something you have only touched (detergents, plants, vegetables, chemicals). So looking for the cause is sometimes really like looking for the proverbial needle in the haystack.

Deciding exactly what has caused the allergic reaction is difficult for several other reasons too:

1. The reaction may take a few hours to a few days to develop; it may not develop immediately.

2. Cosmetic companies are extremely secretive about the ingredients of their products, making it difficult for the patient and the doctor to identify the cause of the rash.

3. The reaction can develop even to minute amounts of the substance and the patient might not even be aware

4. A Moreover, the substance can get on to the skin in all sorts of indirect ways; for example, nail varnish can easily cause reactions on the face because we all touch our face several times a day.
