Understanding Eczema and the Skin Barrier
Babies with eczema often have a weakened skin barrier. When the skin is inflamed, cracked, or irritated, substances applied to the skin can enter the body more easily than they would through healthy skin.
Some research suggests that exposure to food proteins through damaged skin may contribute to the development of food sensitization in susceptible children. This is one reason many specialists recommend caution when applying food-based products directly to active eczema.
Why I Am Careful With Food-Based Skin Products
- The skin barrier is disrupted.
- Proteins from foods may penetrate through broken skin.
- The immune system may recognize these proteins as foreign.
- In some children, this may increase the risk of developing food sensitization or allergy.
Examples include coconut oil, peanut oil, almond oil, oat-based homemade mixtures, and various kitchen remedies. ‘Natural’ does not always mean risk-free, especially when applied to inflamed or broken skin.
Skin Exposure vs. Oral Exposure
Through Damaged Skin: When food proteins enter through inflamed skin, the immune system may be more likely to view them as potential threats.
Through the Mouth: Introducing foods by mouth at the appropriate developmental age allows the digestive and immune systems to develop tolerance to those foods.
This is one reason why maintaining good eczema control and introducing foods according to current feeding guidelines are both important.
What I Usually Recommend Instead
- Thick, fragrance-free moisturizers
- Fragrance-free ointments or creams✓Prompt treatment of eczema flares✓Regular skin barrier protection
- Discussion with your child’s healthcare provider regarding food introduction
- Evaluation by an allergist when eczema is moderate to severe or when food allergy is suspected
Practical Take-Home Message
For babies with eczema, my general preference is: Food is best introduced through the mouth, while eczema is treated with appropriate moisturizers and medications designed for the skin.
Although coconut oil may be tolerated by some children, I typically avoid recommending food-based products on actively inflamed or broken eczema skin until the skin barrier has healed.
