What is Eczema?

Eczema, also known as atopic dermatitis, is a chronic skin condition. It causes dry, itchy, and inflamed skin. It often starts in childhood but can affect people of all ages. The condition is not contagious. It results from a combination of genetics and environmental factors.

Common Triggers and Causes

Eczema has no single cause. It results from a weakened skin barrier and an overactive immune system. Common triggers include:

  • Irritants: Soaps, detergents, shampoos, and disinfectants.
  • Allergens: Dust mites, pet dander, pollen, and mold.
  • Climate: Dry weather, low humidity, or cold temperatures.
  • Stress: Emotional stress can worsen symptoms.
  • Foods: Dairy, eggs, nuts, and soy may trigger flares in some people.
  • Infections: Bacterial, viral, or fungal infections can aggravate eczema.
  • Hormones: Changes in hormone levels can affect symptoms.

Symptoms and Diagnosis

Symptoms vary by person and age. Common signs include:

  • Itching: Often severe, especially at night.
  • Dry, scaly patches: Usually on the face, hands, elbows, or knees.
  • Red to brownish-gray patches: Common in people with lighter skin.
  • Small, raised bumps: May leak fluid when scratched.
  • Thickened, cracked skin: From long-term scratching.
  • Raw, sensitive skin: From scratching.

Diagnosis is based on a physical exam and medical history. Your doctor may ask about family history and triggers. In some cases, a patch test is used to rule out allergies.

Basic Skincare Routine for Eczema

A consistent skincare routine is essential. It helps restore the skin barrier and reduce flares.

1. Gentle Cleansing

  • Use a mild, fragrance-free cleanser.
  • Avoid hot water. Use lukewarm water instead.
  • Limit baths to 10-15 minutes.
  • Pat skin dry with a soft towel. Do not rub.

2. Moisturize Immediately

  • Apply moisturizer within 3 minutes of bathing.
  • Use a thick cream or ointment. Lotions are less effective.
  • Look for products with ceramides, petrolatum, or shea butter.
  • Moisturize at least twice daily.

3. Avoid Irritants

  • Choose fragrance-free laundry detergents.
  • Wear soft, breathable fabrics like cotton.
  • Avoid wool and synthetic fibers.
  • Keep nails short to minimize scratching damage.

4. Use Wet Wrap Therapy

  • Apply moisturizer to affected areas.
  • Wrap with damp gauze or cloth.
  • Cover with a dry layer.
  • Leave on for several hours or overnight.
  • Helps deeply hydrate and soothe.

Over-the-Counter Treatments

OTC options can help manage mild eczema.

  • Hydrocortisone cream (1%): Reduces itching and inflammation. Use for short periods only.
  • Antihistamines: Oral antihistamines like cetirizine can reduce itching, especially at night.
  • Moisturizers with colloidal oatmeal: Soothe and protect the skin.
  • Topical calcineurin inhibitors: Some are available OTC in lower strengths, but most require a prescription.

Prescription Treatments and Therapies

If OTC treatments are not enough, a doctor may prescribe stronger options.

Topical Medications

  • Corticosteroids: Stronger than OTC. Used for short periods.
  • Calcineurin inhibitors: Tacrolimus and pimecrolimus. No steroids. Safe for sensitive areas like face and groin.
  • PDE4 inhibitors: Crisaborole is a non-steroidal ointment.
  • JAK inhibitors: Ruxolitinib cream is a newer option.

Systemic Medications

  • Oral corticosteroids: For severe flares. Short-term use only due to side effects.
  • Immunosuppressants: Methotrexate, cyclosporine, or azathioprine.
  • Biologics: Dupilumab (Dupixent) is an injectable medication for moderate-to-severe eczema.
  • JAK inhibitors: Oral medications like upadacitinib (Rinvoq) and abrocitinib (Cibinqo).

Light Therapy (Phototherapy)

  • Uses UVB or UVA light.
  • Reduces inflammation and itching.
  • Usually done 2-3 times per week.
  • Can be combined with other treatments.

Lifestyle and Home Remedies

Simple changes can improve symptoms.

  • Identify and avoid triggers: Keep a diary to track flares.
  • Manage stress: Try meditation, yoga, or deep breathing.
  • Humidify your home: Use a humidifier in dry climates.
  • Take bleach baths: Add 1/2 cup of bleach to a full bathtub of water. Soak for 10 minutes. Rinse and moisturize. This reduces bacteria on the skin.
  • Use cool compresses: For itchy areas.
  • Wear gloves: When using harsh chemicals or doing dishes.
  • Avoid scratching: Keep nails short and consider wearing cotton gloves at night.

When to See a Doctor

See a dermatologist or healthcare provider if:

  • Your eczema is severe or covers large areas.
  • Itching disrupts sleep or daily activities.
  • You have signs of infection: increased redness, warmth, swelling, oozing, or fever.
  • OTC treatments do not help after 2-4 weeks.
  • You are unsure about your diagnosis.
  • Eczema affects your quality of life.

Early treatment can prevent complications like skin infections and thickening.
