Ear eczema affects the ear canal, outer ear, and behind the ear through different mechanisms — seborrhoeic overlap in the canal, contact allergen reactions on the outer ear, and atopic eczema behind the ear. Here's the specific treatment for each.
Sunbeds & Psoriasis: Why They're Not Phototherapy, the DNA Damage Distinction & What Dermatologists Recommend
UV light helps psoriasis — but sunbeds emit predominantly UVA which causes DNA damage and skin cancer risk without the therapeutic narrowband UVB wavelength that makes phototherapy effective. Here's the wavelength difference, the risk evidence, and how to access NHS phototherapy.
Psoriasis on Lips: How to Identify It, What Helps & What to Avoid
Lip psoriasis is rare but real — and often confused with other conditions. Here's how to identify it, what helps, and why certain common lip habits make it worse.
Vitamin A & Eczema: Why Retinol Often Makes It Worse & When It Actually Helps
Topical retinoids worsen eczema in most presentations — accelerating cell turnover on an already-compromised barrier. But vitamin A deficiency genuinely worsens eczema severity. Here's the distinction that matters.
Protein Powder and Acne: Why It Happens, Which Types Are Worst & What to Switch To
Whey protein is one of the most consistently reported acne triggers — for specific reasons. Here's the mechanism, which other gym factors matter, and what to switch to.
Eczema on Legs: The Three Distinct Types & What Each Needs

Vitamin B & Acne: Which B Vitamins Trigger Breakouts, Which Help & Why B12 Is Different
Some B vitamins may trigger acne — others actively help it. Here's what the science says about B12, B6, biotin, and niacinamide, and what to do if you suspect a link
Gut Health & Acne: The Gut-Skin Axis, LPS Translocation & What Actually Helps
The gut-skin axis is real — intestinal permeability allows LPS from gut bacteria to trigger the same TLR4 inflammatory cascade driving acne. Here's what the evidence shows and what to do about it
Psoriasis on Elbows: Why It Appears There, How to Treat It & Long-Term Management
Elbows are one of the most common psoriasis sites — for specific anatomical reasons. Here's why, how elbow psoriasis differs from other locations, and what actually helps.
Psoriasis Fatigue: Why It's Biological Not Just Poor Sleep, What the Research Shows & What Helps
Psoriasis fatigue is driven by IL-6 and TNF-α crossing the blood-brain barrier — sickness behaviour, not lifestyle. Here's the mechanism, why biologics improve fatigue independently of skin clearance, and what nutritional support addresses the underlying pathways.
Hormonal Acne Diet: The IGF-1 Mechanism, Foods That Raise Androgens & What Actually Helps
High-glycaemic foods and dairy raise IGF-1 and activate mTORC1 — the same androgen-stimulating pathway driving hormonal acne. Here's what to eat, what to avoid, and why spearmint and DIM specifically address the hormonal dimension
