What Is Eczema?

Eczema, also known as atopic dermatitis, is a chronic skin condition that causes the skin to become red, dry, itchy, and cracked. It is not contagious but can significantly affect quality of life due to discomfort and visible skin changes. Eczema often starts in childhood but can occur at any age.

The condition results from a combination of genetic and environmental factors that affect the skin’s barrier function. When this barrier is weakened, the skin loses moisture and becomes more vulnerable to irritants and allergens.

Common Causes and Triggers

Eczema does not have a single cause. Instead, several factors can trigger or worsen symptoms:

• Genetics

People with a family history of eczema, asthma, or hay fever are more likely to develop eczema.

• Irritants

Soaps, detergents, shampoos, and even certain fabrics like wool can irritate sensitive skin.

• Allergens

Dust mites, pet dander, pollen, and mold can provoke flare-ups in some individuals.

• Climate

Extreme temperatures, low humidity, or sudden changes in weather can dry out the skin and trigger eczema.

• Stress

Emotional stress may worsen eczema symptoms, though it is not a direct cause.

• Infections

Bacterial or viral infections can aggravate eczema patches.

Understanding your personal triggers through observation and testing can help reduce flare-ups.

Recognizing Eczema Symptoms

Eczema symptoms vary depending on age and severity but generally include:

• Itching

Intense itching is often the first sign and can lead to scratching that worsens the condition.

• Redness and Inflammation

Affected areas become red and swollen.

• Dry, Scaly Skin

The skin may crack, peel, or become rough.

• Blisters and Oozing

In severe cases, small blisters may form and leak fluid.

• Thickened Skin

Long-term scratching can cause the skin to thicken and develop a leathery texture.

Common areas affected include the face, hands, inside of elbows, and behind knees, but eczema can appear anywhere on the body.

Effective Treatment Options

While eczema has no cure, many treatments can control symptoms and improve skin health. Treatment plans often combine self-care with medical therapies.

Daily Skin Care

• Moisturize Frequently

Use fragrance-free, thick moisturizers or ointments at least twice a day to lock in moisture.

• Gentle Cleansing

Choose mild, soap-free cleansers and avoid hot water to prevent drying the skin.

• Avoid Scratching

Keep nails short and consider wearing cotton gloves at night to reduce damage from scratching.

Lifestyle Adjustments

• Identify and Avoid Triggers

Keep a diary to track flare-ups and avoid known irritants or allergens.

• Manage Stress

Techniques like meditation, exercise, or counseling can help reduce stress-related flare-ups.

• Wear Comfortable Clothing

Choose soft, breathable fabrics like cotton and avoid wool or synthetic fibers.

Medical Treatments

• Topical Corticosteroids

These anti-inflammatory creams reduce redness and itching during flare-ups. Use as directed by a healthcare provider.

• Calcineurin Inhibitors

Non-steroid creams that help control inflammation, especially for sensitive areas like the face.

• Antihistamines

Oral antihistamines can help reduce itching, especially at night.

• Phototherapy

Controlled exposure to ultraviolet light can improve symptoms in moderate to severe cases.

• Systemic Medications

For severe eczema, doctors may prescribe oral or injectable medications that affect the immune system.

When to See a Doctor

If eczema symptoms worsen, do not improve with over-the-counter treatments, or signs of infection appear (such as increased redness, warmth, swelling, or pus), seek medical advice. A dermatologist can provide a tailored treatment plan and may recommend patch testing to identify allergens.

Living Well with Eczema

Managing eczema requires patience and a proactive approach. Regular skin care, avoiding triggers, and following medical advice can keep symptoms under control. Support groups and educational resources can also help people cope with the emotional impact of eczema.

Remember, eczema varies from person to person. What works for one individual may not work for another, so it’s important to find a personalized routine.
