Sensitive Skin: What's Actually Happening, and How to Respond

This article covers cosmetic skin sensitivity: the reactive, easily-irritated skin many people live with day to day. It isn't a substitute for a dermatologist, and if you have a diagnosed condition like eczema, rosacea, or contact dermatitis, that's a medical conversation first.

"Sensitive skin" gets used as a catch-all, which makes it easy to dismiss as vague or overclaimed by half the skincare aisle. It isn't vague, and it isn't rare. Here's what's happening underneath the label, and what helps.

Many people describe their skin as sensitive

A large European survey (Misery and colleagues, published in the Journal of the European Academy of Dermatology and Venereology) polled a representative sample of over 4,500 people across eight European countries. These figures are self-reported: they show how many people described their own skin as sensitive, not how many have a diagnosed condition. Across the sample, 38.4% described their skin as sensitive or very sensitive, with higher figures in Italy and France. The range between countries is wide, and self-reported sensitivity depends on how the question is asked and on how people describe their skin, so these figures shouldn't be read as a clinical prevalence estimate. What they do suggest is that many people notice some skin reactivity at some point, which is a good reason to give it a real answer rather than dismiss it as an afterthought.

How sensitivity works, mechanically

Sensitive skin isn't one single condition with one single cause: it's a pattern of heightened reactivity that can come from several directions at once, and current dermatological research increasingly points to the skin's nerve endings and barrier working together, not separately. A 2020 position paper from the special interest group on sensitive skin of the International Forum for the Study of Itch (Misery and colleagues, in the Journal of the European Academy of Dermatology and Venereology) describes sensitive skin as related to changes in the skin's nervous system rather than an immune disorder, which is why it shows up as stinging, burning, tingling and tightness in response to things that wouldn't bother more resilient skin. Barrier weaknesses are frequently found alongside it, although the paper is clear that one doesn't simply cause the other. Put simply: sensitivity is a nerve-ending story that often travels with a barrier one. That's a useful reframe, because it means the fix usually isn't "avoid everything." It's avoiding your likely triggers, choosing well-tolerated products, and looking after the barrier while you do.

What tends to trigger it

• Over-exfoliation or actives introduced too fast: layering multiple acids or retinoids before skin has adjusted to any of them.
• Fragrance and essential oils: among the most common cosmetic irritants, even in products marketed as "natural" or "gentle."
• Environmental shifts: cold, dry air, wind, and sudden temperature changes are well-documented triggers, which is why sensitivity often gets worse seasonally rather than staying constant.
• Harsh cleansing: surfactants strong enough to strip oil also strip the lipids sensitive skin can least afford to lose.

The microbiome piece

Skin doesn't just have a barrier made of lipids and cells; it also carries a surface microbiome, a community of bacteria that plays a role in how calm or reactive skin is. A microbiome thrown out of balance (by harsh products, over-cleansing, or environmental stress) is associated with a more reactive, less resilient surface. This is the reasoning behind prebiotic skincare: rather than adding bacteria directly the way a probiotic supplement might, prebiotic ingredients feed and support the beneficial bacteria already living on skin, with the aim of a steadier, less reactive surface over time. It's a newer area of skincare than barrier support via ceramides or lipids, and the research base, while promising, is smaller and still developing. It's worth trying if it interests you, not worth regarding as a solved science yet. Our Light Balancing Prebiotic Serum and Balancing Prebiotic Dew Mist are built around this idea. Both are made to help keep skin feeling balanced and hydrated. If your skin is sensitive, we'd always suggest a patch test first, or start with barrier support.

Choosing sunscreen for reactive skin

Sensitive skin faces a real dilemma with sun protection: daily SPF is essential precisely because a compromised barrier is more vulnerable to UV-related irritation, yet many sunscreens are themselves a common trigger. Mineral filters (zinc oxide and titanium dioxide) are often suggested as a starting point for reactive skin, though what really matters is the whole formula and how your skin gets on with it. Our Sun Protect Tinted Fluid SPF30 uses zinc oxide with a sheer, skin-toned tint, made for everyday wear. If your skin is sensitive, we'd always suggest a patch test first.

Why sensitivity can appear out of nowhere

Skin that has never reacted before can become suddenly reactive, and it's rarely down to one single cause. Hormonal shifts, including those during perimenopause and menopause, seasonal changes in humidity and temperature, a new medication, or simply cumulative barrier stress from a routine that's been fine for years can all lower the threshold at which skin starts reacting. The practical response is the same regardless of the cause: strip the routine back to the essentials, reintroduce barrier support first, and give it real time. Newly reactive skin usually takes weeks, not days, to feel calmer, just like any other dry or stressed barrier.

Building a routine that calms rather than reacts

A few principles hold up consistently well for sensitive or reactive skin:

• Fewer products, applied consistently: a five-step routine changed every few weeks makes it hard to identify what's causing a reaction. Simplify first, add back slowly.
• Fragrance-free where your skin is reactive: not because fragrance is inherently bad, but because it's one of the most common and easiest-to-remove variables.
• Patch test anything new: a small amount on the inner forearm for a couple of days before it goes on your face, especially if you have a history of reacting to new products.
• Prioritise barrier support over active ingredients: ceramides and ceramide-adjacent lipids are part of the physical structure that keeps irritants and moisture loss in check, so supporting them is a sensible place to start before adding another active.

Our Ceramide Cocoon Night Cream is built around this barrier-first idea: plant glycosphingolipids and glycolipids with shea and cocoa butter for a rich, cocooning texture. It's made for skin that feels dry or tight. If your skin is sensitive, we'd always suggest a patch test first, or start with our Red Algae Calming Night Cream, which is made for sensitive skin.

In short

Sensitive skin is common, mechanistically real, and usually responds better to fewer, calmer products and real barrier support than to chasing symptoms one at a time. If you want to start simply: fewer products, a gentle overnight cream, and patience while your skin settles. That takes weeks, not days.
