Different skin allergies – causes and treatments 2018

Skin allergies affect the lives of millions of people around the world. Although most are not life threatening or painful, these allergies affect patients’ quality of life.

Skin allergies occur when the immune system responds to an allergen. Sometimes the immune system incorrectly identifies substances or even body parts as a threat and causes an allergic skin reaction.

Here is a breakdown of a number of skin allergies:



Eczema occurs when the skin does not store enough moisture and dries, stings and becomes inflamed. The skin is also flaky and cracked. Eczema is usually found in the folds of the arms and legs. This chronic allergy to the skin undergoes periods of relapses and remissions. Many people are born with skin diseases because of genetics or develop during childhood. This may be due to exposure to harmful chemicals or allergens. While most children lose their eczema, some retain it as an adult.

How to Treat Eczema

Eczema can be treated by adding sufficient moisture to the skin. Ensuring that the skin is clean and does not scratch the infected area helps to treat allergies. Topical creams, steroid creams, cortisone creams and emollients help to heal the affected skin.

According to Robert Sidbury, chief physician of dermatology at Seattle Children’s Hospital, research shows that eczema co-exists with several diseases, such as hay fever and asthma. It has also been found that children with eczema are more likely to develop ADHD.



Dermatography is a rare skin allergy that affects about 5% of people. According to Dr. Adrian Morris, a leading allergist in allergy clinics in Cape Town and Johannesburg, has dermatography or “skin writhing” when mast cells in the skin produce too much histamine. Histamine is released with any form of stimulation or pressure on the skin. What develops is inflammation and itching of the skin. The reaction can be identified as a white or red inflamed line on the skin. Dermatologist Amanda Oakley says the cause of dermatography is unknown, but in some cases it may be an allergic reaction to a foreign substance.

How to Treat Dermatography 

In some cases, dermatography takes only one or two years, while in other cases it lasts indefinitely. It is not harmful or deadly and rarely associated with pain. Allergies can be treated with antihistamines or apply a cold compress to the area to reduce swelling.

Like dermatography, urticaria is a skin allergy that causes rashes. These markers can vary in size; They are accompanied by itching and usually occur on the arms and legs. The body produces these beehives when the mast cells of the skin produce too much histamine. However, when these cells release large quantities of chemicals to combat the allergen, the fluid infiltrates the bloodstream, which can cause anaphylaxis.

How to Treat urticaria

As with dermatography, urticaria can be treated with antihistamines and steroids. Some relief can be provided if the affected area is not scraped. A cold compress works too. Avoiding alcohol and junk food can also help to reduce breakouts. A recent study shows that medications normally used for asthma can be used to treat this skin allergy.

Heat rash

Heat rash

A Heat rash occurs when the skin is exposed to warm temperatures, but the sweat channels are blocked and can not release perspiration. Also known as thorny, clogged sweat ducts causes inflammation of the skin and the formation of red bumps and itching. A study shows that the obstruction of the sweat ducts is due to a biofilm produced by the bacteria Staphylococcus in the skin. The heat eruption can occur both in summer and in winter. It is also common for babies to have too hot or underdeveloped pores. The heat eruption is not contagious.

How to Treat Heat rash

The heat eruption usually disappears by itself. Keep the body cool and avoid friction or tight clothing will help with this skin allergy. Distance from the sun also helps to reduce inflammation. Try to avoid scented and exfoliating lotions as they can irritate the skin.
