A Simple, Natural Skincare Routine

You do not need ten products. A simple routine protects and repairs skin. The skin barrier (stratum corneum) = bricks (corneocytes) + mortar (lipids: ceramides, cholesterol, fatty acids). Over-cleansing, over-exfoliating, layering actives damages mortar -> dehydration, sensitivity, inflammation. Minimalist routine: cleanse, moisturise, protect. Evidence: 3-step non-negotiable. Everything else = targeted, temporary, optional.

What Science Says

Cleanser: surfactant removes sebum, dirt, sunscreen. Harsh surfactants (SLS) strip lipids -> TEWL ↑. Gentle: syndet bars, cream cleansers, pH 5.5. Moisturiser: occlusive (petrolatum, dimethicone), humectant (glycerin, hyaluronic acid), emollient (ceramides, squalane) -- repair barrier, reduce TEWL. Sunscreen: UVB (burning, DNA damage), UVA (ageing, deeper penetration). Broad spectrum SPF 30+ = 97% UVB blocked. Daily use -> 24% less ageing (Australian RCT). Reapply 2h outdoors. Actives (retinoids, vitamin C, niacinamide, AHAs/BHAs) = evidence-based but secondary -- add ONE at a time, 3 months minimum.

How It Works

AM: (1) Cleanse: splash water or gentle cleanser if oily. (2) Moisturise: lightweight, barrier-support (ceramides, glycerin). (3) Sunscreen: ¼ tsp face/neck, broad spectrum SPF 30--50. PM: (1) Cleanse: gentle cleanser (double cleanse if sunscreen/makeup). (2) Treat (optional): ONE active -- retinoid (anti-ageing/acne), niacinamide (barrier/pores), azelaic acid (rosacea/acne), vitamin C (AM preferred). (3) Moisturise: richer if dry, same if oily. Weekly: gentle chemical exfoliant (AHA 5--10% / BHA 1--2%) 1--2x -- not with retinoid same night.

Pros & Cons

Pros

• Barrier intact = less sensitivity, better active tolerance

• Cost-effective -- 3 products vs 10

• Time-efficient -- 3 min AM, 4 min PM

• Travel-friendly, decision-free

Cons

• No targeted actives -- slower results for specific concerns

• Boring -- marketing sells routines, not basics

• May need adjustment: seasons, hormones, treatments

• Sunscreen reapplication = real-world challenge

Expert Tips

• Cleanser pH 5.5 -- check brand site or test strips

• Moisturiser on damp skin (within 3 min) = locks max water

• Sunscreen: 2mg/cm² = ¼ tsp face. Most apply 25--50% -> SPF 15 effective

• Retinoid: start 0.025% 1x/week, build over 3 months. Buffer with moisturiser.

• Vitamin C: L-ascorbic 10--20%, pH <3.5, opaque airless pump. AM under sunscreen.

How to Implement

1. Audit current products -- keep only cleanser, moisturiser, SPF

2. Buy 3 quality products (drugstore OK: Cerave, La Roche-Posay, Neutrogena)

3. Run 4 weeks -- no new products

4. Add ONE active if desired -- 3 month trial

5. Quarterly review: barrier check (stinging, tightness, breakouts)

Side Effects & Precautions

• Retinoids: pregnancy/contraindicated -- bakuchiol alternative (less evidence)

• Active + active = irritation -- space: retinoid night, vit C AM, niacinamide either

• Compromised barrier (eczema, rosacea, post-procedure): basics only, derm guidance

• Photosensitising meds (doxycycline, isotretinoin, some diuretics) -- SPF 50+, UPF clothing

• Children <6 months: shade, clothing -- no sunscreen; 6m+ mineral SPF

Bottom Line

Three steps: cleanse, moisturise, protect. Done daily for decades = best anti-ageing. Actives are seasoning -- the meal is the barrier.
