What Causes Eczema in Babies & How to Prevent It

by Alesha Fleischhacker

Nothing is more important than your baby's comfort. So, when you see your little one struggling with dry, itchy, or inflamed skin, it's only natural to worry—and to search for answers. Baby eczema is a common skin condition that affects up to 20% of infants worldwide. Although it often improves with age, it can be an ongoing concern during those precious first months and years.

If you're wondering what causes eczema in babies, you're not alone. The truth is, there isn't just one cause. Genetics, allergens, and environmental factors all play a role. The good news? With the right knowledge and care routine, you can reduce the likelihood of flare-ups and help your baby's skin stay healthy and happy.

Let's explore the underlying causes of infant eczema, how genetics can influence it, practical prevention tips, and the best skincare habits for your baby.

Understanding the Causes of Baby Eczema

Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition characterized by red, dry, scaly, and itchy patches of skin. In babies, it most commonly appears on the cheeks, scalp, and outer limbs, but it can appear anywhere on the body.

So, what causes eczema in babies?

1. Genetics

The most significant factor is family history. If either parent has eczema, hay fever, asthma, or food allergies, the baby is more likely to develop eczema. These conditions are all part of what's called the "atopic triad," and they often occur together.

2. Weakened Skin Barrier

Healthy skin acts like a shield, locking in moisture and keeping irritants out. Babies with eczema have a compromised skin barrier, making it easier for allergens, bacteria, and irritants to penetrate and cause inflammation.

3. Environmental Triggers

Common culprits include:

  • Dry air (especially in winter)

  • Hot baths or soaps with harsh chemicals

  • Dust mites and pet dander

  • Pollen

  • Laundry detergents and fabrics with synthetic dyes or fragrances

Even changes in weather or overheating from too many layers of clothing can trigger a flare-up.

4. Food Allergens

While food isn't always the cause, some babies with eczema may be sensitive to certain foods like dairy, eggs, peanuts, or soy. This is more likely if eczema starts before six months of age or if there are other signs of a food allergy, like hives or digestive issues.

5. Immune System Sensitivity

Babies have developing immune systems. In some, the immune response to allergens or irritants becomes overactive, causing inflammation in the skin.

Understanding these causes is the first step in managing your baby's eczema. Next, let's look at how genetics factor into the equation.

How Genetics Plays a Role in Infant Eczema

Eczema often runs in families, and science has confirmed that genetics is a key piece of the puzzle.

The FLG Gene Connection

One of the most researched genes linked to eczema is the filaggrin (FLG) gene. This gene is responsible for producing a protein that helps maintain the skin's barrier function. If your baby inherits a mutated version of this gene, their skin is more likely to lose moisture and allow irritants to seep in, leading to the dry, itchy, inflamed skin characteristic of eczema.

Hereditary Allergies

If you or your partner have a history of allergies or asthma, your child is at a higher risk of developing eczema. This inherited sensitivity may cause the immune system to overreact to environmental or food triggers, resulting in eczema flare-ups.

While we can't change our genetics, we can take proactive steps to minimize their impact on our babies' skin health. Here's how.

Top Ways to Prevent Eczema Flare-Ups in Babies

Preventing eczema in babies starts with avoiding triggers and protecting the skin. Here are science-backed tips to help reduce the risk of flare-ups:

1. Keep Skin Moisturized Daily

Moisturizing helps repair the skin barrier. Use a thick, fragrance-free emollient at least twice a day, especially after baths. Look for products labeled "hypoallergenic" and "suitable for sensitive skin."

2. Choose Skin-Friendly Clothing

Natural fibers like bamboo and organic cotton are soft and breathable, reducing friction and irritation. Avoid wool and synthetic materials, which can cause overheating or itchiness.

Pro tip: Caribou Kids offers beautifully crafted bamboo clothing that's not only gentle on the skin but also stylish and designed to grow with your child.

3. Bathe Wisely

Stick to lukewarm baths lasting no more than 10 minutes. Avoid bubble baths or harsh soaps. After the bath, gently pat the skin dry and apply moisturizer immediately to seal in moisture.

4. Watch for Allergens

If you suspect a food allergy, talk to your pediatrician before removing anything from your baby's diet. For environmental allergens, use dust-mite-proof covers, wash bedding weekly in hot water, and keep pets out of sleeping areas.

5. Use Gentle Detergents

Laundry soaps with fragrances and dyes can irritate sensitive skin. Opt for unscented, hypoallergenic detergents, and avoid fabric softeners altogether.

6. Maintain Comfortable Indoor Air

Use a humidifier during dry months to add moisture to the air. Keep your baby's room at a cool, comfortable temperature to prevent overheating, which can aggravate eczema.

7. Monitor Changes in Skin

Catching a flare-up early is crucial. At the first sign of dryness or redness, ramp up your moisturizing routine and remove potential irritants.

Preventing eczema isn't just about avoiding triggers—it's also about nurturing healthy skin. Let's discuss creating the perfect skincare routine for your baby.

Best Skincare Routine for Eczema-Prone Babies

If your baby has sensitive or eczema-prone skin, a consistent skincare routine is your best defense. Here's a step-by-step guide:

Morning Routine

  1. Gentle Cleanse (if needed): If your baby had a sweaty night or a diaper blowout, use lukewarm water and a mild, fragrance-free cleanser.

  2. Moisturize: Apply a generous layer of emollient all over the body. Focus on common eczema-prone areas like the cheeks, arms, and behind the knees.

  3. Dress in Soft Layers: Choose bamboo or organic cotton clothing that's breathable and doesn't trap heat.

Midday Tips

  • Spot Moisturizing: Keep a travel-size moisturizer on hand for dry patches or after diaper changes.

  • Sun Protection: If you're going outdoors, dress your baby in protective clothing and use a mineral-based baby sunscreen on exposed areas.

Evening Routine

  1. Bath Time: Keep it short and sweet—around 5–10 minutes. Use only water or a gentle, eczema-safe cleanser.

  2. Moisturize Immediately: Within three minutes of toweling off, apply a thick layer of moisturizer to lock in hydration.

  3. Nightwear: Choose breathable pajamas. Look for seamless designs to reduce friction.

Consistency is key. Even on days when the skin looks fine, don't skip the routine—it helps prevent future flare-ups.

Happy Skin, Happy Baby

Eczema in babies can be distressing, but understanding the causes, like genetics, allergens, and environmental factors, empowers you to take control. With a few intentional lifestyle changes and a mindful skincare routine, you can help keep your baby's skin soft, smooth, and flare-free.
