Skincare
Evidence-led skin care — actives, concentrations, tolerability, and knowing when to see a doctor.
How Moisturising Actually Works: Occlusives, Humectants, Emollients, and Ratios by Skin Type
Starting from natural moisturising factor and transepidermal water loss, this separates humectants, emollients, and occlusives, with concrete ratios for skin type and season.
Scalp and Hair: Oiliness, Dandruff and Shedding - Causes and a Care Routine
Oily scalp, flaking, and hair fall are different problems with different drivers. This separates them, covers what evidence supports, and where a clinician must step in.
Where At-Home Devices Stop and In-Clinic Treatment Begins: Radiofrequency, IPL, Microneedling
Home RF, IPL, and microneedling pens are popular but bounded by safety law. This maps what each can realistically do and where only a clinician's energy and training change the outcome.
Hands and Nails: Hangnails, Dryness, and Nail Plate Damage
Hands age fastest and nails signal health. This covers preventing dryness and hangnails, protecting the nail plate, and the habits and signs that mean a clinician.
Acne by Grade: Comedones, Inflammatory Papules, Nodules and Cysts - and Where Self-Care Ends
Grade acne by type and severity - comedones, inflammatory papules, nodulocystic - with what to use, how often to reassess, and the step that must go to a doctor.
Sensitive Skin and Barrier Repair: Recognising Over-Cleansing, Simplifying, and the Repair Timeline
Sensitivity is a symptom, not a diagnosis. This gives the signals of over-cleansing, a minimal-ingredient checklist, a real repair timeline, and the line to a doctor.
The Three-Step Baseline: Cleanse, Moisturise, Protect - What the Evidence Actually Supports
Only three daily habits have repeated randomized-trial backing. Here are the exact doses, frequencies, and self-checks that make them work.
The Anti-Aging Timeline: What to Spend Money On at 25, 35 and 45, Ranked by Evidence
Rank anti-aging methods by evidence strength, then by age band, and separate what skincare can change from what only a clinician can.
Sunscreen, Completely: SPF and PA/UVA-PF, Mineral vs Chemical Filters, Dose, Reapplication, Water Resistance, Removal
SPF and PA are lab numbers measured under strict conditions. This breaks down filter types, the dose math, reapply timing, and removal so the label value becomes real-world protection.
Pigmentation: The Melanin Pathway, Actives That Work, and Why Sunscreen Is Non-Negotiable
From tyrosinase to melanosome transfer, this separates pigment types, ranks active-ingredient evidence, and explains why no serum outranks sunscreen.
Seasonal Skincare: Transitioning Through Flare-Ups and Summer Oil Control
How to shift the routine across seasons without breaking the barrier, calm winter flare-ups, and keep summer oil and sweat from driving breakouts.
Body Care: Keratosis Pilaris, Roughness, Body Moisturisers and Exfoliation Frequency
From 'chicken skin' on the arms to ashiness on the shins, this covers what drives body roughness, which actives move it, and how often to exfoliate without triggering it.
The Ingredient Class: Retinol/Retinal, Niacinamide, Vitamin C - Mechanisms, Concentrations, and What Not to Combine
From receptor binding and melanosome transfer to redox potential, this covers the concentration ladder, tolerance schedules, and the combinations that genuinely clash.
