Skin · Chapter Two · Ten Concerns

What it's doing right now.

Type is a constitution. Concern is a behaviour. Your skin type tells you something about structure; your current concern tells you something about what your skin is actually doing this month, in this climate, under this level of stress. Each concern here is a four-to-six week calendar of decisions — not a single product, not a one-night fix. Find the behaviour. Build the protocol.

What your skin is doing now.

56 protocols total →
01
/ dehydration

Dehydration

The fine lines that appear when you press the skin together, then vanish. The face that looks dull at noon despite moisturiser applied at seven. Dehydration is not dryness — it is a water question, not a lipid one — and the protocol is about pulling moisture into the skin before sealing it, in that order, with that distinction understood.

6 protocols
02
/ dullness

Dullness

The flat, grey quality that replaces clarity in late January, after a long-haul flight, after three weeks of disrupted sleep. Most people reach for a brightening serum; the real fix is usually circulation and dead-cell accumulation — both of which respond better to consistent exfoliation and warmth than to any ingredient stamped with a percentage.

5 protocols
03
/ uneven-tone

Uneven Tone

The face that looks patchy rather than clear — redness around the nose, a different colour at the jaw, a mottled quality that no foundation quite corrects. Uneven tone is frequently a barrier issue dressed up as a pigment issue, and the products sold to fix it are often the cause of the patchiness they claim to address.

6 protocols
04
/ post-inflammatory-marks

Post-Inflammatory Marks

The flat, pink or brown marks that remain after a blemish clears. Not raised, not active — just a stain the skin is slowly reabsorbing. The mistake is impatience: applying strong actives to speed the process and extending it instead. The protocol is mild, consistent, and measured in weeks rather than days.

5 protocols
05
/ texture

Texture and Roughness

The bumpy surface that catches concealer, grips powder unevenly, and looks smoother in photographs than it ever feels. Usually a dead-cell story — the skin's natural shedding cycle is outpaced by accumulation. The correction is regular, gentle exfoliation rather than the occasional aggressive one that promises to reset everything in a single session.

6 protocols
06
/ congestion

Congestion

The persistently bumpy chin and forehead, the blackheads at the nose that survive every scrub, the pores that visibly fill again within a week of extraction. Congestion is a pore-lining question and responds to consistent BHA use — slow, low-irritant, twice weekly — rather than the mechanical removal approach that clears and refills on a predictable cycle.

5 protocols
07
/ barrier-damage

Barrier Damage

The skin that stings products it once accepted without complaint. The routine that worked for two years and now causes redness after every application. Barrier damage is almost always a self-inflicted concern — too many actives, applied too often, in the conviction that more correction is better. The protocol for repairing it involves removing most of the routine, not adding to it.

6 protocols
08
/ fine-lines

Fine Lines

Age-aware care: the protocols for expression lines, forehead creasing, and the periorbital area that becomes more visible with dehydration, less visible when the barrier is intact. Most fine lines visible before forty respond better to hydration and barrier health than to concentrated actives — a fact the active-ingredient industry has little incentive to confirm.

6 protocols
09
/ under-eye-darkness

Under-Eye Darkness

The shadow that reads as exhaustion whether or not you are tired. Under-eye darkness has three distinct causes — structural shadow from the orbital hollowing that deepens with age, vascular pooling that reads as bluish-purple, and flat pigmentation that reads as brown — and each requires a different approach. Treating all three identically explains why most eye creams disappoint.

5 protocols
10
/ hyperpigmentation

Sun Spots and Hyperpigmentation

The flat, pigmented patches concentrated at the cheekbones and temples that deepen after holidays and fade slowly through winter. Of all the concerns here, this is the one where the intervention is most binary: vitamin C in the morning, SPF immediately after, every day without exception. The actives are supportive. The sun protection is the treatment.

6 protocols
Editor's note Nelly · Beauty Director On concern
vs. condition
The most useful thing you can do before starting any targeted protocol is to sit with the concern for two weeks without adding anything new. What you are trying to fix is often a reaction to the last fix you applied. Subtraction is a protocol. Patience is an active ingredient.
— Nelly Whitcombe · Beauty Director · Spring 2026

Why concern is the more honest entry point.

Type tells you who you are. Concern tells you what your skin is doing right now, under current conditions, with current habits. The second question is almost always more useful.

Why most routines fail at the gap between formulas

There is a persistent belief that a failing routine needs better products. In practice, a failing routine almost always needs a clearer diagnosis. Skin concern is more specific than skin type — it names the behaviour rather than the constitution — and specificity is where protocols either work or don't. Oily skin and dry skin are both capable of producing a congestion concern. Dehydration appears across every skin type, in every climate, in every decade. If the type is the category, the concern is the question the category cannot answer on its own.

The gap where most routines break down is not formulation quality. It is the space between two products that each individually make sense but which, applied in sequence, cancel each other or provoke a response the user attributes to neither. Vitamin C applied over a compromised barrier. Retinol introduced alongside AHA exfoliation in the same week. A niacinamide serum layered beneath an occlusively applied oil. None of these combinations are obviously wrong; each product has a legitimate claim to being useful. But the gap between them is where the concern lives, and the gap is what targeted protocols address.

Consistency beats novelty, every time

The skincare industry is structured around the proposition that the next formula will do what the current formula cannot. This is occasionally true and regularly false. Barrier repair, tone correction, and texture improvement are each calendar concerns — they operate on a timeline of weeks rather than sessions, and that timeline requires consistency rather than innovation. A vitamin C serum used every morning for six weeks does more for hyperpigmentation than three weeks of that serum followed by three weeks of a new alternative. The protocol is not just the ingredients. It is the sustained commitment to applying them.

Novelty is also frequently the cause of the concern it promises to treat. Barrier damage is almost never caused by a single over-aggressive product; it is caused by the accumulation of individually reasonable products applied in combinations the skin was not given time to accept. The most reliable protocol for barrier repair is the removal of most of the current routine, not the addition of a barrier-repair serum to the pile of products that compromised it.

Concern changes; the discipline doesn't

Your current concern is not permanent. Dehydration resolves. Post-inflammatory marks fade. Texture smooths with consistent exfoliation. The concern you are addressing in January is not necessarily the concern you will be addressing in September — climate, travel, hormonal shifts, and seasonal changes all move the needle. What persists is the discipline of diagnosis: identifying the current behaviour clearly, building a protocol specific to it, giving that protocol the full four-to-six weeks to produce observable results, and then reassessing. The concern changes. The approach to it stays the same.
