Common Causes of Eczema


For most of the cases of eczema, the main causes still remain unclear. However, we do know that different cases have different causes. It is important to identify the reason for individual people to help control their problem better.

Some of the most common eczema triggers include:

Dry skin

Dry skin tends to easily become brittle, scaly, rough, or tight than normal skin. Therefore, it can cause an eczema flare up.


Results from recent studies have shown that emotional stress is known to be associated with eczema. Some people with existing eczema can experience that their symptoms get worse when they are under stress. Others may become stressed because of their eczema, and this can make their skin flare up.


Some common bacteria or viruses that live in the environment such as Staphylococcus aureus (“staph”), the molluscum virus, herpes virus (fever blisters and cold sores), and certain kinds of fungus (ringworm or athlete’s foot) can infect your skin and cause eczema. Sometimes we can come across with more than one type of these bacteria. There are a lot of skin micro-organism that can trigger the infection.  It’s important to notice such popular symptoms of these different infections and what causes them so that your eczema can be under controlled.

Irritants- Allergens

There are daily products, materials, and even natural substances that can cause you an allergic reaction and trigger eczema (or AD) flare up. This can lead your skin to burn and itch, or become dry and red. Some of the most common irritants can be the products that you use on your body or. Hand and dish soap, laundry detergent, shampoo, bubble bath and body wash, or surface cleaners and disinfectants, and even several cosmetic applied on your skin can be the allergens. There are several allergens which are more likely to come across in everyday life including seasonal pollen, dust mites, pet dander from cats and dogs, mold, and dandruff.  Even some natural products, such as the juice from fresh fruit, vegetables, or meats, can cause eczema when you expose to them. Allergens cause symptoms to short time and disappear, or to come back, or can be a long-term problem. It’s important to identify the allergens, irritants that could cause an eczema flare up to keep it out of your reach.


Hormones refer to substances which are produced by the body gland and its can cause a wide variety of symptoms. When the levels of several hormones in your body such as insulin increase or decrease, some people with eczema (especially women) may experience flare-ups.

Hot/Cold temps and sweating

Sweat can cause eczema. Hard exercising, wearing too many clothes to bed, or quickly moving from one extreme temperature to another (cold to hot), can make you feel itchy or experience a “prickly heat” sensation.

These trigger above are the most common eczema causes and triggers. It is important to know them and avoid the risk factors to have a better skin health.
