Microplastics & Eczema: The TLR4 Inflammatory Mechanism, What the Research Shows & What to Do
Microplastic particles activate TLR4 receptors and trigger the same NF-κB inflammatory cascade that drives eczema — while nanoplastics penetrate eczema's compromised barrier more efficiently than intact skin. Here's what the research shows.
Flying with Eczema: The 10–15% Humidity Mechanism, Cortisol Stress Response & What to Do
Aircraft cabin humidity drops to 10–15% — far below the 40–60% threshold comfortable for eczema skin. Combined with cortisol stress elevation and recycled air histamine exposure, flying is one of the most specific eczema environments there is. Here's what helps.
A Psoriasis-Friendly Morning Routine: Step by Step
A psoriasis morning routine is about reducing inflammatory inputs before the day adds more. Here's a step-by-step guide with the reasoning behind each habit.
Can Vaping Make Eczema Worse? What the Evidence Actually Shows
Vaping is marketed as cleaner than smoking — but e-cigarette aerosol contains compounds that may worsen eczema through specific mechanisms. Here's what the evidence shows.
Best Sunscreen Habits for Eczema-Prone Skin
Finding a sunscreen that doesn't irritate eczema-prone skin is hard — but not impossible. Here's what to look for, what to avoid, and specific products worth trying.
Eczema in Summer: Why Heat Triggers Flares & What Actually Helps
Summer heat worsens eczema through specific mechanisms — heat-triggered histamine release, sweat irritation, and pollen overlap. Here's what's happening and what helps.
Vibration Plates for Psoriasis: What They Can Do, What They Can't & the Koebner Consideration
Vibration plates have no direct psoriasis evidence — but the exercise and inflammation relationship is real. Here's an honest look at what they can and can't do.
Tea Tree Oil for Eczema: The Terpinen-4-ol Mechanism, the Oxidation Risk & How to Use It Safely
Tea tree oil's terpinen-4-ol inhibits S. aureus — the bacterium most associated with eczema severity. But oxidised tea tree oil is significantly more allergenic than fresh, and contact sensitisation rates are high. Here's the honest picture.
Vitamin D and Eczema: What the Evidence Actually Shows
Vitamin D deficiency is more prevalent in eczema patients and linked to disease severity. Here's what it does, what the research shows, and the UK-specific context most articles miss.
Castor Oil for Psoriasis: The Ricinoleic Acid Mechanism, Koebner Risk & What Works Better
Castor oil's ricinoleic acid has mild anti-inflammatory properties — but its high viscosity means massage application carries a Koebner risk on psoriatic plaques. Here's when it helps and when to avoid it.
The Contraceptive Pill & Eczema: Oestrogen, Progesterone Sensitivity & Nutrient Depletion Explained
The contraceptive pill depletes zinc, magnesium, and B6 — all specifically relevant to eczema barrier function and immune regulation. Here's the hormonal mechanism and what to do about it
Olive Oil for Psoriasis: The Oleic Acid Barrier Concern, Scalp Use & Better Alternatives
Olive oil softens psoriatic scale — but its high oleic acid content disrupts ceramide synthesis in an already-compromised barrier. Here's when topical olive oil helps, when to avoid it, and what the dietary evidence actually shows
