Dermatologist's quick take
- Sensitive skin reacts to product, climate, stress — sometimes all three
- Four products is enough: cleanser, moisturiser, sunscreen, repair serum
- Strip everything for 2 weeks before reintroducing one item at a time
- Mineral SPF (zinc/titanium) is gentler than chemical filters
- Identify whether it's true sensitivity or impaired barrier — the fix differs
Sensitive skin is the most over-treated skin type I see in clinic. Patients walk in with shopping bags of products specifically marketed as "for sensitive skin" — most of which contain fragrance, essential oils, or botanical extracts. Almost every routine I prescribe for true sensitive skin is shorter, simpler and cheaper than what people arrived with.
The principle is the same whether your sensitivity is from rosacea, eczema, perioral dermatitis, or a damaged barrier from over-exfoliation: get out of the way, let the barrier rebuild, then slowly reintroduce only what's evidence-backed and necessary.
Sensitive skin or damaged barrier?
Roughly 70% of people who think they have "sensitive skin" actually have a barrier damaged by years of over-cleansing, harsh actives, or fragrance. The two look identical but the fix is different.
Damaged barrier
- Reacts to products you previously tolerated
- Calms within 2–4 weeks of stripping the routine
- Often follows a period of over-exfoliation or strong actives
- Improves dramatically with ceramide-based moisturiser
True sensitivity
- Reactive across years, not just recently
- Triggered by climate, sun, temperature — not just product
- Often runs in family (atopic, rosacea, eczema)
- Reacts even to fragrance-free, simple products
The 2-week reset
Before any new routine, do this: cleanser + bland moisturiser + mineral SPF only, for 14 days. No actives, no acids, no retinol, no fragrance, no botanicals. This is your diagnostic baseline. If skin calms, you had a barrier problem. If it doesn't, you have true sensitivity and need a longer-term plan.
The 4-product sensitive skin routine
Product 1 — Gentle, fragrance-free cleanser (AM and PM)
Cream or milk cleanser, pH around 5.5, no sulphates, no fragrance. Keep cleansing time under 45 seconds. In the morning, a water rinse alone is acceptable.
Product 2 — Barrier-repair serum (PM)
Niacinamide (4–5%), panthenol, centella asiatica, or beta-glucan. These calm inflammation, strengthen the barrier, and reduce redness over 4–8 weeks. Apply on damp skin under moisturiser.
Product 3 — Ceramide moisturiser (AM and PM)
Look for a 3:1:1 ratio of ceramides, cholesterol and fatty acids — the ratio your skin barrier is naturally made of. Brands like CeraVe PM, La Roche-Posay Toleriane Double Repair, and Avène Tolérance Control all formulate this way.
Product 4 — Mineral SPF 30+ (AM)
Zinc oxide and/or titanium dioxide are physical filters that sit on top of the skin and reflect UV. They're significantly less likely to irritate than chemical filters (avobenzone, octinoxate, oxybenzone). The downside: they can leave a white cast on darker skin tones — look for tinted formulas if needed.
Cleanse
Gentle, fragrance-free, 30–45 sec.
Repair
Niacinamide or centella, PM only.
Moisturise
Ceramide cream, AM and PM.
Sun protect
Mineral SPF 30+, AM.
Ingredients to always avoid
The 'do not buy' list for sensitive skin
- Fragrance — synthetic AND most natural fragrances
- Essential oils — especially lavender, citrus, peppermint, tea tree
- Denatured alcohol high on the ingredient list
- Sulphates (SLS, SLES) in cleansers
- Physical scrubs and brushes
- AHA/BHA above 5% concentration to start
- Hydroquinone without dermatologist supervision
When sensitivity is something else
If your "sensitive skin" includes persistent flushing, visible blood vessels, or pustules → likely rosacea. If it includes itchy, scaly patches that come and go → likely eczema. If it appeared after a specific new product → likely allergic contact dermatitis. Each needs a different treatment plan, and a free AI skin analysis via ScanSkinAI can help you triage which one to investigate first.
Red flags — see a dermatologist
- Painful, burning sensitivity that doesn't improve with the 2-week reset
- Visible blistering, weeping or crusted patches
- Sudden new sensitivity in someone who's never had it before
- Reactions to almost every product, including fragrance-free
How long until you see improvement
Most barrier damage resolves within 2–4 weeks of the reset. True sensitivity calms over 8–12 weeks with consistent use of the 4-product routine. Track changes objectively with ScanSkinAI — small, consistent improvements are easy to miss without photos.

Frequently Asked Questions
Yes — about 50% of women and 38% of men report sensitive skin in dermatology surveys. It's a clinical pattern of stinging, burning, redness, or tightness in response to products or environment, with or without visible inflammation. It's distinct from rosacea, eczema and contact dermatitis, though it overlaps with all three.
Strip your routine for 2 weeks (gentle cleanser + bland moisturiser + SPF). If skin calms down, it was barrier damage from products. If it stays reactive to environment (wind, sun, temperature), it's true sensitivity. Most people are 70% damage, 30% sensitivity.
Fragrance (synthetic and most natural — see our fragrance in skincare guide), essential oils, denatured alcohol, sulphates, physical scrubs, AHA/BHA above 5%, retinol above 0.3% to start, and most botanical extracts.
Often the opposite. Essential oils (lavender, citrus, tea tree), botanical extracts and natural fragrances are among the most common allergens we see in patch-test clinics. Look for short ingredient lists and minimal botanicals.
Yes, but slowly. Start with retinaldehyde 0.05% or encapsulated retinol 0.2%, twice a week, applied over moisturiser ('sandwich method'). Build up over 12+ weeks. Skip during active flares.
Apply a small amount to the inside of your forearm or behind your ear, twice daily for 7 days. If no reaction, apply to a small patch on the side of the face for 3 more days before full use. See our patch test guide for details.
