The Oil You Cook With Is Affecting Your Skin
Most eczema families focus on what they eat — but not what they cook in. The oil in your pan gets absorbed into your food, and what your body processes affects your skin barrier, inflammation levels, and immune response.
Here's what you need to know about the 3 main categories:
🚫 Seed Oils:
Canola, vegetable, sunflower, safflower, soybean, corn oil…
Seed oils are the most widely used — and the most problematic for inflammatory skin conditions.
They are extremely high in omega-6 fatty acids. In small amounts, omega-6 is necessary. But the modern diet already delivers far too much of it, and excess omega-6 tips the body toward a pro-inflammatory state. For someone with eczema, that internal inflammation often shows up on the skin.
Seed oils also oxidize rapidly under heat, producing compounds that stress the body's detox pathways. The liver has to work harder, and when the body is overwhelmed, the skin often becomes a secondary elimination route — contributing to flares.
Bottom line: These are the oils most worth removing from your kitchen first.
⚖️ Animal Fats:
Grass-fed butter, ghee, tallow, lard, duck fat
Animal fats have a better omega-6 to omega-3 ratio than seed oils, especially when sourced from grass-fed animals. Ghee in particular is well-tolerated — it's clarified, meaning the milk solids are removed, which makes it easier for people with dairy sensitivities.
Tallow and lard are stable under high heat, meaning they don't oxidize the way seed oils do. Less oxidation means less inflammatory byproduct in your food.
From a TCM perspective, small amounts of high-quality animal fat can actually support the Spleen and nourish Blood — both of which are commonly deficient in eczema patterns.
The nuance: source quality matters significantly. Conventionally raised animal fat carries a different nutritional profile than pastured or grass-fed sources.
Bottom line: Quality animal fats, used moderately, are a reasonable upgrade from seed oils for most eczema families.
✅ Plant-Based Oils: Extra virgin olive oil, coconut oil, avocado oil
These are generally the most skin-friendly options when used correctly.
Extra virgin olive oil is high in oleic acid and polyphenols, which have well-documented anti-inflammatory properties. Best used at low-to-medium heat or drizzled raw — it degrades above its smoke point.
Coconut oil has medium-chain fatty acids and antimicrobial properties. It's heat-stable and gentle on digestion. In TCM, it supports the Spleen and is considered warming — beneficial for eczema patterns tied to cold and dampness. (Note: a small subset of people with eczema react to coconut oil topically or internally, so observe your child's individual response.)
Avocado oil is one of the most heat-stable plant oils and has a mild flavor. Rich in vitamin E and oleic acid, it supports skin membrane integrity.
Bottom line: For most eczema families, rotating between extra virgin olive oil and avocado oil is a practical, lower-inflammation approach.
