Anxiety & Eczema: Why the Connection Is Deeper Than 'Stress Causing a Rash'
Anxiety and eczema share a specific and bidirectional biological relationship — not just "stress causes flares." Here's the mechanism and what the evidence shows for breaking the cycle
Beef Tallow for Acne: What the Fatty Acid Profile Actually Tells You
Beef tallow is trending for acne-prone skin — but its fatty acid profile tells a more complicated story than TikTok suggests. Here's the honest assessment.
Anti-Inflammatory Drinks for Psoriasis: What the Research Actually Shows
Some drinks have specific anti-inflammatory mechanisms relevant to psoriasis. Here's an honest assessment of the evidence for each — green tea, oolong, coffee, kombucha, and more.
Eczema and Dairy: The IgE vs Non-IgE Distinction, What the Evidence Shows & How to Test It
Dairy and eczema have a real but nuanced relationship — IgE milk allergy is different from non-IgE delayed reactions. Here's how to tell them apart and whether elimination is worth trying.
Cold Water Therapy & Psoriasis: What the Evidence Shows & What to Watch Out For
Cold water therapy has plausible mechanisms for psoriasis — but cold urticaria, Koebner risk, and dryness are real concerns. Here's the honest evidence and practical guide.
Cleansers for Eczema: What Works, What Doesn't & the SLS Warning
The wrong cleanser is one of the most common eczema mistakes. Here's the SLS mechanism, the aqueous cream cautionary tale, and what to use instead.
Mouth Taping for Acne: Trend, Myth or Helpful Habit? What the Evidence Shows
Mouth taping has no direct evidence for acne — but the sleep quality it aims to improve does. Poor sleep elevates cortisol through HPA axis dysregulation, increasing sebum production and worsening inflammatory acne. Here's the honest picture.
Apple Cider Vinegar for Psoriasis: The Acetic Acid Mechanism, Scalp Use Protocol & Why It Burns
ACV's acetic acid temporarily restores the skin's acid mantle and has mild antimicrobial activity — but at psoriasis skin's elevated permeability it penetrates deeply enough to cause chemical burns. Here's the dilution protocol and when to avoid it
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.
Ultra-Processed Foods and Psoriasis: What the Research Shows
Research increasingly links ultra-processed food intake to active psoriasis — through specific inflammatory, metabolic, and gut microbiome mechanisms. Here's what the evidence 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.
LED Masks for Acne: Blue Light, Red Light, What the Research Shows & Is It Worth It
LED masks have genuine evidence for mild-to-moderate acne — but the mechanisms matter, and at-home devices are considerably weaker than clinical treatments. Here's the honest guide.
