Quick answer: Eczema (atopic dermatitis) involves a weakened skin barrier and an overactive immune response, and it is often linked with allergies, gut health and inflammation. Daily skin-barrier care is the foundation: lukewarm showers, fragrance-free products and moisturizing right after bathing. Probiotics, omega-3s, vitamin D, GLA oils and identifying personal triggers can add support.
What drives eczema
- A weaker skin barrier, sometimes from genetic differences in proteins such as filaggrin
- Immune overactivity and histamine
- Gut and microbiome imbalances
- Food or environmental triggers in some people
- Stress and dry climates
Daily skin care
- Lukewarm, short showers, then moisturize within minutes
- Fragrance-free, gentle cleansers and ceramide-rich moisturizers
- Wet wraps or colloidal oatmeal during flares
- Soft, breathable fabrics
Nutrients commonly used
- Probiotics: some strains are studied for eczema
- Vitamin D: supports skin and immune function; guided by testing
- Omega-3s: support a healthy inflammatory response
- Evening primrose or black currant oil (GLA): used for skin barrier support
- Quercetin and vitamin C: support a balanced histamine response
- Zinc: supports skin repair
- Gut support: such as glutamine and collagen (see supporting the gut barrier)
Amounts should be individualized. If you work with me, the products I use are in my Fullscript dispensary.
Identifying triggers
Some people react to specific foods such as dairy, eggs or wheat. A guided elimination and reintroduction can help identify them, especially for children, who need careful nutrition planning. See managing food sensitivities.
Is testing helpful?
Allergy testing can help when food or environmental allergy is suspected. Stool testing may add insight in complex cases. Functional labs are optional. They can be helpful in more complex cases, and in my practice they are available only to patients working 1-on-1 with me.
Eczema and healthy aging
Chronic skin inflammation adds to whole-body inflammatory load and oxidative stress. Supporting the skin barrier and calming immune overactivity helps the skin stay resilient over time.
When to see a naturopathic doctor
- Eczema that keeps flaring despite good skin care
- You want to identify food or environmental triggers
- You want natural support alongside your dermatologist’s plan
- Your child has eczema and you want a gentle, safe approach
See a medical provider promptly for eczema that is oozing, crusting, very painful or spreading quickly, or with fever. These can be signs of infection.
