At 10, why is my son’s eczema coming back post-treatment?

Question

Hello doctor,

My son is 10 years old and has been dealing with eczema for the past two years. Every few weeks, red and itchy patches appear again on his elbows, behind the knees, and sometimes on his neck. The skin becomes very dry, and he scratches a lot, especially at night, which sometimes causes small cuts and irritation.

We apply moisturizers daily and occasionally use the steroid cream prescribed by the doctor, which helps for a while, but the rash keeps returning after a few weeks. He also has a history of seasonal allergies and occasional wheezing during weather changes.

His recent blood test showed elevated IgE levels (around 380 IU/mL), but his hemoglobin is normal (12.5 g/dL). Please tell me,

Why does eczema keep coming back every few weeks, even after treatment?
Are there specific triggers like food, dust, weather changes, or stress that could be causing these repeated flare-ups?
What long-term skin care routine or treatments can help reduce the frequency of these episodes?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Eczema in children is most commonly known as atopic dermatitis. It is a chronic inflammatory skin condition and is very common in children who also have allergies, asthma, or allergic rhinitis. From the history you described (recurrent itchy patches in the elbow folds, behind the knees, neck, night-time itching, and elevated IgE), the pattern is strongly suggestive of atopic dermatitis.

Eczema either flares and improves in cycles rather than disappearing permanently. Even when steroid creams improve the rash, the underlying skin barrier weakness and immune hypersensitivity remain, which is why the condition returns after a few weeks.

Three main factors contribute to your son’s repeated flare-ups:

A defective skin barrier in your son with eczema causes skin that loses moisture easily and allows irritants and allergens to penetrate. This leads to dryness, itching, and inflammation.
Your son’s allergic tendency (atopy), elevated IgE levels, and a history of allergies or wheezing indicate an atopic background. This means the immune system is more reactive to environmental triggers.
Night-time scratching can damage your son’s skin further, causing small cuts and worsening inflammation, which triggers more itching.

Common triggers that may cause your son’s flare-ups are,

Dust mites and indoor allergens.
Weather changes, especially winter dryness or excessive sweating in summer, can trigger eczema.
Harsh soaps, fragranced products, or detergents.
Rough fabrics such as wool or synthetic clothing.
Excessive bathing with hot water.
Skin infections due to scratching.
Stress or poor sleep.
Food allergies (less common, but sometimes relevant in children).

Long-term skin care routine for your son’s eczema includes;

Apply a thick, fragrance-free moisturizer at least 2–3 times daily. It can be applied immediately after bathing while the skin is slightly damp.
Gentle bathing habits are good for your son. You can use lukewarm water and limit baths to about five to 10 minutes.
You can use mild, soap-free cleansers. However, you must avoid scrubbing the skin.
Keep your child’s nails trimmed short.
Topical steroid creams should be used during flare-ups as prescribed to control inflammation. Topical calcineurin inhibitors are indicated for sensitive areas.

I hope this information helps you.
