Skin allergy resulting in a rash

Almost everyone knows someone who suffers from it or has dealt with it themselves, and therefore knows that a skin allergy is no fun. A rash can be a result of a skin allergy, but it can have more causes. Skin allergy is one of the most common chronic diseases in the world and can be found in many variants. For example, some people experience very severe itching and redness, while for others this skin allergy manifests itself in blisters, bumps or flaking of the skin.

How does a skin allergy develop?

A skin allergy can occur when the skin comes into contact with a certain substance or, for example, when a certain substance is ingested or inhaled to which one is allergic. People can get this allergic reaction from certain foods such as walnuts or strawberries, cosmetics, medicines and soap. This allergic reaction that people get, such as red bumps, is also called eczema; a collective name for various skin diseases.

Medicines for skin allergy

If you are also dealing with a skin allergy, you can of course do something about it.

Do not come into contact with allergens

Firstly, provided you know this, you can ensure that you do not come into contact with the product or substance to which you are allergic. So if you are allergic to walnuts, you should avoid walnuts when consuming them.

Skin allergy medication

Secondly, there are also various medicines against a skin allergy. The most effective for an allergic skin reaction are antiallergic agents in the form of a tablet. Examples include cetirizine and loratidine. Various medicines are also available in the form of an ointment. If you have dry skin, it is a good idea to use a greasy ointment, cream or bath oil.

Do I have a skin allergy?

If you strongly suspect that you are allergic to a certain substance, you can have an allergy test done to be sure. You can have an allergy test done by a skin specialist. First your skin is cleaned and then various boxes are drawn on your arm and numbered. A drop of a certain substance is placed on the skin in each box, which must remain on the skin for ten minutes. If you are allergic to a certain substance, the skin in that area will become very red and thick. In most cases, a white bump also appears, such as with a mosquito bite. The larger the bump, the worse the allergy is to the particular substance. An allergy test takes about thirty minutes in total and is in most cases performed on the inside of the forearm. After it is clear which substances the person is allergic to, the drops are removed from the forearm with a special lotion.
