The Root Cause of Your Baby's Eczema
What most people get wrong
Eczema is often managed or viewed as just a skin issue, and the typical response reflects that: a cream to calm the visible rash. That approach makes sense on the surface, but the rash itself is a result of an internal dysfunction rather than the starting point. While a cream can ease discomfort while internal work happens, cream alone misses the root cause of the condition.
Why eczema occurs
Eczema can result from several factors compounding at once rather than a single clear cause, with skin barrier function being one of the most significant. Skin relies on lipids and a protein called filaggrin to retain moisture and keep irritants out. In children with eczema, lipid structure is often altered and filaggrin production is reduced, allowing moisture to escape more easily and irritants to penetrate more deeply than they should.
Gut health plays a substantial role as well. When the intestinal lining is more permeable than it should be (a state commonly referred to as leaky gut), undigested food particles can enter the bloodstream. The immune system responds to these particles as foreign material, and the resulting inflammation can present in the skin.

Genetics and environmental exposure also play roles. Though genetics alone doesn't determine the outcome, a family history of eczema, asthma, or allergies increases the likelihood of eczema developing. Dry climates, hard water, harsh soaps, and household allergens all place additional demand on a system that’s already under strain.
Why food is a trigger, not the root cause
Food can reliably set off a flare, but it's rarely the reason a child is prone to flares in the first place. This is part of why eczema can develop before a baby has started solids. It’s also why elimination diets alone often fail to clear eczema long-term.
Eczema and food sensitivities frequently share the same underlying issue: a gut and immune system that need support. Eliminating a trigger food can provide meaningful relief, but it has to be combined with deeper support. On its own, it's rarely a complete resolution.
Supporting the body internally
At OBN, we’ve developed a protocol that involves: “The 4 R’s.”
Removing
• Identifying food sensitivities
• Reducing exposure to triggers
Rebalancing
• Building the microbiome
• Diversifying beneficial gut bacteria
Repairing
• Strengthening integrity of the intestinal barrier
Restoring
• Optimizing nutrient absorption
It can take time and dedication, but it can be very effective. It certainly isn’t a one-size fits all approach, though. The protocol requires each step being individualized for each child’s unique needs. If you’re interested in getting support from a Certified Nutrition Consultant that specializes in eczema, please see our Consultant Database.
External supports
Topically, lanolin (specifically the medical-grade, HPA type) is one of the more effective options for locking moisture into the skin while internal support takes hold. Petroleum-based products and steroid creams can offer fast relief from visible symptoms, but they don't address what's happening beneath the surface, so they're best used sparingly rather than as a long-term strategy.
Progress may not be linear
Most families notice meaningful improvement within the first month of consistent support, though fully resolving eczema often takes three to eight months. Flare-ups during that window are common and don't indicate that something isn't working, they're just a normal part of identifying what a child's body needs.
