Atopic Dermatitis
What is Atopic Dermatitis?
Atopic dermatitis is a chronic skin condition that causes red, itchy, and inflamed patches of skin. It is also commonly called eczema. This condition occurs when your immune system overreacts to triggers in your environment or diet. The result is ongoing inflammation that damages the skin barrier and leads to discomfort.
Atopic dermatitis often starts in childhood but can affect people at any age. The condition tends to come and go in cycles. You might experience flare-ups when exposed to certain triggers, followed by periods when your skin improves. Many people with atopic dermatitis also have allergies, asthma, or hay fever.
The condition is not contagious and cannot spread from person to person. It reflects an underlying immune system imbalance that causes your body to react strongly to things that normally would not cause problems. Understanding your specific triggers can help you manage symptoms and reduce flare-ups.
Symptoms
- Red or brownish-gray patches on the skin
- Intense itching, especially at night
- Small raised bumps that may leak fluid when scratched
- Dry, cracked, or scaly skin
- Thickened skin from repeated scratching
- Raw or sensitive skin from scratching
- Skin that appears darker or lighter after healing
Symptoms often appear on the hands, feet, ankles, wrists, neck, chest, eyelids, and inside the bend of elbows and knees. Some people experience mild symptoms while others have severe itching that disrupts sleep and daily activities. In infants, the rash often appears on the face and scalp.

Causes and risk factors
Atopic dermatitis develops from a combination of genetic factors and immune system dysfunction. People with this condition often have a gene variation that affects the skin's ability to retain moisture and protect against bacteria, allergens, and irritants. When the skin barrier is weak, irritants can penetrate more easily and trigger inflammation.
Common triggers include environmental allergens like pollen, dust mites, pet dander, and mold. Food allergens such as dairy, eggs, nuts, and wheat can cause flare-ups in some people. Other factors include harsh soaps, fragrances, stress, sweat, dry air, and temperature changes. Having family members with eczema, asthma, or allergies increases your risk of developing atopic dermatitis.
How it's diagnosed
Doctors diagnose atopic dermatitis by examining your skin and asking about your symptoms and medical history. There is no single test to confirm eczema. However, allergy testing can help identify specific triggers that worsen your condition. Blood tests that measure immunoglobulin E levels and specific allergen antibodies can reveal which substances your immune system reacts to.
Your doctor may recommend testing for common allergens including grasses, trees, pet dander, dust mites, and foods. Identifying these triggers allows you to avoid them and reduce flare-ups. While Rite Aid focuses on general wellness testing, specialized allergy panels for eczema management may require a referral to an allergist or dermatologist. Talk to our doctor about testing options that fit your needs.
Treatment options
- Apply moisturizer to damp skin at least twice daily to lock in moisture
- Use gentle, fragrance-free soaps and detergents
- Take short lukewarm baths or showers, not hot ones
- Identify and avoid your specific allergen triggers
- Apply prescription steroid creams during flare-ups to reduce inflammation
- Use antihistamines to reduce itching, especially at night
- Try topical calcineurin inhibitors for sensitive areas like the face
- Consider wet wrap therapy for severe cases
- Manage stress through relaxation techniques and adequate sleep
- Keep fingernails short to minimize skin damage from scratching
Frequently asked questions
Atopic dermatitis and eczema are the same condition. Eczema is the common term people use, while atopic dermatitis is the medical name. Both refer to chronic inflammation of the skin that causes itching, redness, and discomfort. The term eczema can also refer to other types of skin inflammation, but atopic dermatitis is the most common form.
Many children with atopic dermatitis see their symptoms improve or disappear as they grow older. However, some people continue to have flare-ups throughout adulthood. Even when symptoms are not active, the tendency for eczema remains. Proper skin care and avoiding triggers can keep the condition well-managed for long periods.
Blood tests that measure immunoglobulin E levels show whether your immune system is overreacting. Specific IgE tests can identify which allergens trigger your symptoms, such as grasses, pet dander, dust mites, or foods. Knowing your triggers helps you avoid them and reduce flare-ups. These specialized allergy panels usually require a referral to an allergist.
No, atopic dermatitis is not contagious and cannot spread from person to person. The condition results from a combination of genetic factors and immune system dysfunction. You cannot catch eczema by touching someone who has it. However, scratching can introduce bacteria and lead to skin infections that may require treatment.
Common food triggers include dairy products, eggs, wheat, soy, nuts, and shellfish. However, food triggers vary greatly from person to person. Some people have no food-related triggers at all. If you suspect certain foods worsen your symptoms, work with a doctor to identify them through elimination diets or allergy testing.
You should moisturize at least twice daily, preferably right after bathing while your skin is still damp. This helps lock in moisture and repair your skin barrier. During flare-ups or in dry weather, you may need to moisturize more frequently. Choose thick, fragrance-free creams or ointments rather than thin lotions.
Yes, stress is a well-known trigger for eczema flare-ups. When you are stressed, your body releases hormones that can increase inflammation and weaken your skin barrier. This makes your skin more reactive to other triggers. Managing stress through relaxation techniques, exercise, and adequate sleep can help reduce flare-ups.
See a doctor if over-the-counter treatments are not controlling your symptoms or if your eczema interferes with sleep and daily activities. You should also seek medical care if you notice signs of infection like increased pain, warmth, pus, or fever. A dermatologist can prescribe stronger medications and help identify your specific triggers.
Some people find relief with colloidal oatmeal baths, coconut oil, or sunflower seed oil applied to the skin. Probiotics and omega-3 fatty acids may help reduce inflammation in some cases. However, natural remedies should complement, not replace, medical treatment. Always discuss supplements and alternative treatments with your doctor before trying them.
Diet changes alone rarely cure atopic dermatitis, but avoiding food triggers can significantly reduce flare-ups in some people. An anti-inflammatory diet rich in fruits, vegetables, and omega-3 fatty acids may help support skin health. Work with a healthcare provider to identify your specific food triggers rather than eliminating foods unnecessarily. A balanced approach to diet, skincare, and medical treatment works best.
