Eczema is a skin condition and illness also called atopic dermatitis. It can be caused by an allergy to a particular food. The resultant symptom of this disease also involves irritation and itching to the skin. The main food products responsible for triggering eczema into action involve wheat, soy and dairy products.

There is no one test that can confirm the diagnosis of eczema, and that is the reason why physicians rely on a patient's family history to diagnose the disease.

Photoaging or Sun Damage

Photoaging and sun damage also lead to red lines on skin, especially the face. The condition results in the formation of highly visible red veins on cheeks, nose, ears and face.

Rash that looks like scratches can be formed on the skin when our immune system misbehaves. Some people's immune system is allergic to peanuts, nuts, eggs and shellfish and starts attacking these food products. When our immune system assumes a food to be an allergen, it starts to produce immunoglobulin E and histamines in the blood stream. These chemicals cause our skin to become irritated and we start scratching our skin. As we scratch our skin, it gives the appearance of rashes and/or scratches.



Skin writing is another name given to the condition dermatographia. Even light scratching of skin by people suffering from this condition can cause the scratches to redden and turn into a raised wheal just like in the case of hives. Such marks do not last longer than half an hour.

Although it is not known what causes dermatographia, penicillin, infections and emotional distress are known to trigger the condition in some people.
