The exact cause of eczema is unknown. Factors that may contribute to eczema include:
- Allergies—These may include allergies to things that touch the skin (such as wool or perfumes in soaps), allergies to dust mites (very common), or allergies to foods.
- Stress, especially if it leads to scratching
- Frequent washing of affected areas
- Use of rubber gloves in persons sensitive to latex
- Scratching or rubbing of skin
A risk factor is something that increases your chance of getting a disease or condition.
- Age: five years old or younger (eczema becomes less common after the ages of 5-10)
- Asthma, hay fever , or seasonal allergies
- Urban areas or places with low humidity
- Relatives who have eczema or allergic disorders
- Race: Black or Asian
The symptoms of eczema vary from person to person. Scratching and rubbing can cause or worsen some of the symptoms.
- Dry, itchy skin
- Cracks behind the ears or in other skin creases
- Rashes on the cheeks, arms, and legs
- Red, scaly skin
- Thick, leathery skin
- Small, raised bumps on the skin
- Crusting, oozing, cracking, or scaling of the skin
- Worsening in the winter, when inside air is dry due to central heating
Your doctor will ask about your symptoms and medical history, and perform a physical exam. You may be referred to a doctor who specializes in skin disorders (a dermatologist) and/or allergies (an allergist).
The main goals of eczema treatment are to:
- Heal the skin and keep it healthy
- Stop scratching or rubbing
- Avoid skin infection
- Prevent flare-ups
- Learn to avoid scratching
Treatment options may vary and your doctor may recommend more than one depending on your condition. They include:
- Avoid hot or long (15 minutes or more) baths or showers.
- Use mild, unscented bar soap or nonsoap cleanser sparingly.
- Air-dry or gently pat dry after bathing and apply gentle moisturizer immediately.
- Treat skin infections immediately.
- Prescription creams and ointments containing cortisone, tacrolimus, or pimecrolimus
- In the most severe cases, oral medications such as prednisone or cyclosporine
- Antibiotics applied directly to the skin or taken by mouth (only for treating infections)
- Prescription or over-the-counter antihistamines to help prevent itching
- Treatment with ultraviolet light (by a doctor)
It can be difficult to prevent eczema, particularly when there is a strong family history. Some studies suggest that breastfeeding reduces a child’s risk of developing eczema. But if you already have eczema, there are several things you can do to try to control it:
- Follow guidelines for limiting house dust mites in bedding.
- Avoid direct contact with wool to the skin.
- Seek advice from your doctor about any use of “natural” or herbal remedies. Some of these may worsen eczema.
- Avoid scratching or rubbing whenever possible.
- Follow your doctor’s recommendations for treatment. Improvement may take several weeks or even months after a new medication is started.
- Maintain a cool stable environment and consistent humidity levels.
- Recognize and limit emotional stress.
