Your skin. Finally explained.

Skin care, finally organised the way you actually use it. Six dimensions — skin type, skin concern, routine, ingredients, technique, and by age — written by a beauty editor with a chemistry degree, edited for the way real skin behaves. No panic copy. No miracle promises. Authoritative and warm at the same time.

The six dimensions of the skin chapter

Skin Type

Routines and product choices sorted by what your skin actually feels like at four in the afternoon — oily, dry, combination, sensitive, normal. Forget the label that came with you in your twenties; skin type drifts, and the routine that respects it has to drift along. Includes five finders and thirty-eight techniques tuned to the constitution your face is currently presenting, not the one that was diagnosed in a dermatologist's chair fifteen years ago. URL: /en/skin/skin-type/

Skin Concern

Targeted protocols for the things skin actually does — texture, tone, dullness, dehydration, redness, post-inflammatory marks. Each protocol is a calendar, not a single product, because the skin you have today was built over the last six weeks of decisions. We cover eleven concerns across sixty-four protocols, including hyperpigmentation maps, dehydration recovery, and the long, patient work of quieting a reactive barrier without stripping it back to nothing. URL: /en/skin/skin-concern/

Routine

AM and PM order of operations, frequency calendars, and minimum-viable routines for travel, stress, and the weeks that quietly fall apart. The right routine is one you can do tired — at the end of a long day, in a hotel bathroom, in a relationship that just ended. Four routine cycles, twenty-seven sequences, and a frequency calendar that distinguishes between the actives you do daily and the ones that should be alternated by the night of the week. URL: /en/skin/routine/

Ingredients

What each active actually does, what it pairs with, what it cancels — written for adults, not for the back of a serum bottle. Retinoids, vitamin C, niacinamide, ceramides, alpha hydroxy acids, beta hydroxy acids, peptides, azelaic acid, polyhydroxy acids — explained the way a senior chemist would explain them to a friend. Twenty-two actives in total, each with a pairing matrix, an effective concentration window, and a list of the conditions where the ingredient genuinely is the wrong tool for the job. URL: /en/skin/ingredients/

Technique

The hand movements. Press versus rub, where heat helps, when to layer damp, and the four minutes between cleansing and SPF that decide whether the rest of your shelf is doing its job. The most overlooked variable in skincare isn't the formula — it's the wrist. Fourteen techniques, nine full walkthroughs, with timing cues, hand pressure cues, and a damp-versus-dry layering chart that resolves more skincare problems than any single product launch ever has. URL: /en/skin/technique/

By Age

Twenties through perimenopause and beyond — protocols that respect how skin actually changes, without the panic copy. Hormones, collagen, barrier integrity, and the cumulative weight of ultraviolet exposure all move on different timelines, and the routine has to know which one is happening this year. Five decade-aware protocols across thirty-one routines, written with the working assumption that the reader is intelligent and the goal is information, not anxiety. URL: /en/skin/by-age/

How to use this chapter

The dimensions are doors, not boxes. Skin Type is the most familiar starting point because it's the question you were asked at the counter when you were nineteen. Skin Concern is the more honest one — concern is a behaviour, type is a constitution, and the routine you build off concern outperforms the routine you build off type almost every time. Routine is where the order of operations lives. Ingredients is the technical layer. Technique is the part the brands don't sell, because they can't bottle it. By Age is where the protocol meets the calendar.

If you only have ten minutes

Click into Routine, find the AM/PM cycle that matches the time you actually have, and ignore everything else for six weeks. Consistency outperforms selection.

If you've been at this a while

Click into Ingredients and read the pairing matrix. Most experienced routines are doing too much — three actives stacked, a barrier quietly inflamed, and a tightness at the cheekbones that the user has learned to call normal.

If you're in your forties or fifties

Click into By Age, then Skin Concern. The protocols there are paced for hormonal shifts and barrier-first introductions.

Editor's note from Nelly

If your skin keeps doing something you don't want, the answer is almost always one of three things — you're cleansing too aggressively, you're layering too much, or you're not waiting long enough between steps. Fix the wrist before you fix the formula. Nelly Whitcombe, Beauty Director, Spring 2026.

Frequently asked questions

In what order should I apply my skincare?

Thinnest to thickest, water-based before oil-based. Morning: cleanse, antioxidant serum, lighter hydrator, moisturiser, SPF. Night: double-cleanse, treatment if it is a treatment night, hydrating serum, moisturiser. Wait sixty seconds between layers — not because the science demands it, but because rushed application is the most common reason routines do not work.

How often should I exfoliate?

Once or twice a week is enough for most skin. Daily acid toners are usually too much. If you are using a leave-on alpha or beta hydroxy acid every night, pull back to two or three nights and watch the redness, the tightness and the small flakes resolve over a fortnight.

Does expensive skincare actually work better?

Sometimes. The premium often buys a more elegant texture, better packaging and a nicer experience — not necessarily better ingredients. Money on serums is usually money better spent than money on cleansers.

Can I use retinol and vitamin C together?

Yes — most modern formulations are compatible — but separating them is still the cleanest approach. Vitamin C in the morning to support sun protection and tone, retinoid at night to do the slower structural work. If your skin is sensitive or new to actives, alternate nights for the first two months.

Do I need a separate eye cream?

Not strictly. The skin around the eye is thinner and dryer, so a richer ingredient list helps — but you can extend a barrier-supporting moisturiser up to the orbital bone with a clean ring finger and get most of the benefit. Eye creams earn their keep in fragrance-free, low-irritation formulas for very reactive skin.

Should I use SPF if I am indoors all day?

If you sit by a window, yes. UVA passes through glass and is responsible for most photoaging. If your day is genuinely four windowless walls and you commute in the dark, you can be more flexible — but the routine stays simpler when SPF is non-negotiable.

My skin is oily — do I still need moisturiser?

Yes. Skipping moisturiser tells oily skin it is under-hydrated and the response is more oil. A light, water-based gel moisturiser supports the barrier without weight. Niacinamide formulas regulate sebum and keep the skin calm without the strip-and-shine cycle.

How long until I see results from a new product?

Hydration: a few days. Texture and tone: four to six weeks. Pigment and collagen: three to six months. The most common mistake is judging an active in week two and abandoning a routine that would have worked. Take a photograph in the same light at week zero, week six and week twelve.

The longer view of the skin chapter

Why the dimensions are organised this way

Most skincare libraries are organised the way the industry sells, which is to say by product category — cleansers, moisturisers, serums, masks. That is a shelf, not a way of thinking. The skin chapter is organised by the questions a real person asks when they look in the mirror at six in the evening, in the kind of light that is honest. They do not ask, what is in my serum drawer. They ask, what type is this. What is happening here. What should I do tonight. What is in this. What is the right way to do it. Where am I in my life. The six dimensions answer those six questions. Nothing else.

The chapter's editorial register

Every page on the skin chapter is written in what we call the clinical-warm register. It is meant to read the way a senior beauty editor with a chemistry background would talk to a friend at a kitchen table — informed, unhurried, occasionally funny, and always more interested in what is true than what is fashionable. The voice is allowed to be specific. Brand names appear when a brand has earned the citation, never as a paid mention. Concentrations are named when the concentration is doing the work. Routines are timed in seconds and minutes when the timing matters, and unfussy when it does not. The reader is presumed to be intelligent, busy, and skeptical, and we treat that as a compliment.

What the chapter deliberately does not include

We do not diagnose skin conditions. Acne grade three and above, rosacea subtypes, eczema flares, perioral dermatitis, melasma, contact dermatitis — these belong with a board-certified dermatologist who can see your skin in person, run a patch test if necessary, and watch you over months. The chapter signals when a concern crosses into clinical territory and points the reader towards medical care. We do not chase trend ingredients without evidence. We do not run before-and-after photographs that would not survive a forensic colour test. We do not rank brands. We rank techniques. We rank protocols. We rank consistency over novelty, every time.

Skin Type — what to expect on the L2 page

The Skin Type page opens with a thirty-second skin type finder — a five-question diagnostic that places the reader in one of five constitutions: oily, dry, combination, sensitive, normal. The finder is calibrated against tightness reports at the cheekbones, midday shine at the T-zone, the time the skin takes to recover after cleansing, and the response history to common actives. The five constitutions branch into routine recommendations, frequency calendars, and the four or five ingredients that earn their keep within each one. The page also includes a short essay on why skin type drifts, why hormonal events shift the constitution sometimes overnight, and why the most common skincare mistake in the late twenties through mid-thirties is doing the routine that worked at twenty-two for skin that no longer matches.

Sub-techniques inside Skin Type

The L3 routes inside skin type include /skin/skin-type/oily/, /skin/skin-type/dry/, /skin/skin-type/combination/, /skin/skin-type/sensitive/, and /skin/skin-type/normal/. Each L3 page carries a constitution-specific routine, a layering map, an actives shortlist, and a do-not-do list. The do-not-do lists are deliberately the longest section on each page, because most reactive routines are reactive because of an ingredient or a step that the reader could simply remove.

Skin Concern — what to expect on the L2 page

The Skin Concern page treats concerns as behaviours, not diagnoses. The eleven concerns it covers are texture, tone, dullness, dehydration, redness, post-inflammatory marks, congestion, fine lines, loss of firmness, dark circles, and visible pores. Each concern carries a six-week protocol — a calendar, in essence — that walks the reader through introduction, escalation, and consolidation phases. Most reactive skin is reactive because the protocol got introduced all at once. The protocols here introduce one variable at a time, with built-in observation windows of two weeks before the next variable is added.

The hyperpigmentation map

Hyperpigmentation is the most asked-about concern on the network and the one most often mishandled. The L3 page at /skin/skin-concern/hyperpigmentation/ separates post-inflammatory hyperpigmentation from melasma, sun-induced lentigines from hormonal patterning, and tropical-climate readers from temperate-climate readers, because the protocols differ. Tyrosinase inhibitors, retinoid sequencing, daily SPF, and the patient calendar of three to six months are explained in plain language. We avoid the language of erasure. The skin you have is not a defect.

Routine — what to expect on the L2 page

The Routine page is the operational heart of the chapter. It carries four cycles — full AM/PM, minimum-viable, travel, and recovery — alongside twenty-seven sequences keyed to skin types and concerns. The minimum-viable routine is the most read protocol on the chapter, because it answers the question most readers actually have on a Tuesday night: what are the two things I cannot skip. The travel cycle is engineered for hotel bathrooms, dehydrating cabin air, and the time-zone-disrupted skin that follows. The recovery cycle is built for skin returning from over-exfoliation, sun damage, or the period after a treatment.

The frequency calendar

The frequency calendar in /skin/routine/frequency/ resolves the most common scheduling question — how often, exactly, do I use the actives on my shelf. Retinoids start at two nights a week and graduate over six weeks. Alpha hydroxy acids and beta hydroxy acids alternate with retinoid nights. Vitamin C is daily morning, every morning, without exception, because antioxidant load matters more than any single application. Niacinamide is daily, AM and PM, in either a serum or moisturiser. The calendar is presented as a printable grid that survives the bathroom counter.

Ingredients — what to expect on the L2 page

The Ingredients page is the technical layer of the chapter. Twenty-two actives are mapped against their effective concentration windows, their pairing partners, their cancellation pairs, and the conditions where the active is the wrong tool for the job. Retinoids — retinol, retinaldehyde, adapalene, tretinoin — are explained as a family, with introduction protocols pegged to skin reactivity. Vitamin C is split by form: l-ascorbic acid, sodium ascorbyl phosphate, magnesium ascorbyl phosphate, tetrahexyldecyl ascorbate, ascorbyl glucoside. Each form has different stability, different penetration, and different appropriate concentration. Niacinamide, ceramides, panthenol, hyaluronic acid, and squalane are covered as the barrier-supporting cohort. Alpha hydroxy and beta hydroxy acids are split by depth and skin friendliness. Peptides are sorted by mechanism. Azelaic acid, polyhydroxy acids, and tranexamic acid each get their own L3 page.

The pairing matrix

The pairing matrix at /skin/ingredients/pairing/ is the most-printed page on the chapter. It resolves the three pairings readers ask about most: retinoid with vitamin C (separable, ideally split AM/PM), retinoid with alpha hydroxy acid (alternate nights for most users), and benzoyl peroxide with retinol (separable, BP morning, retinoid night, with caveats). The matrix is colour-coded — green for compatible, amber for sequenceable, red for genuine conflicts — and the rationale for each cell is one paragraph long. Nothing here is dogmatic. Modern formulations have moved past several of the old conflicts. The matrix tells the reader where the chemistry has caught up and where the caution still applies.

Technique — what to expect on the L2 page

The Technique page is the chapter's quiet centrepiece. Fourteen techniques, nine full walkthroughs. Press versus rub. The cleansing balm dwell. The damp-skin layering window. The ringer-finger orbital application. The two-finger cheekbone press for serums. The four-minute pause between cleanse and SPF. Heat — when it helps and when it does the opposite. Friction — almost always the wrong move. The walkthroughs are illustrated with hand-cue diagrams and timing notation. The premise of the page is that the most overlooked variable in a skincare routine is not the formula in the bottle. It is the wrist that applies it.

The damp-skin layering window

The damp-skin layering window is a technique most readers have heard about and few apply correctly. The window is the sixty to ninety seconds after cleansing during which the skin is still humid enough that hydrating ingredients lock in dramatically better than they do on dry skin. The page at /skin/technique/damp-layering/ walks through it: pat dry, do not towel rub, apply hydrating toner or essence to damp skin within thirty seconds, layer the serum on still-damp skin, and seal with the moisturiser before any tightness sets in. Done correctly, the routine that follows is forty per cent more hydrating than the same routine applied on dry skin, with no formula change.

By Age — what to expect on the L2 page

The By Age page treats the decades as protocols, not labels. The twenties are about establishing the non-negotiables — sun protection daily, gentle cleanse, barrier-respecting moisturiser, an antioxidant serum, and the introduction of a low-dose retinoid in the late twenties. The thirties layer in concern-led protocols: pigmentation, fine lines around the eyes, the first hormonal shifts. The forties carry the perimenopausal protocol, where oestrogen decline thins the dermis and changes the way the skin holds moisture. The fifties and beyond move into the post-menopausal protocol, with peptide-led collagen support, ceramide-rich barrier work, and a pared-back routine that prioritises consistency over complexity. Each decade has thirty-one routines spread across skin type and concern combinations, so the reader can find a protocol that matches both the age and the constitution.

The perimenopausal protocol

The perimenopausal protocol at /skin/by-age/perimenopause/ is one of the most quietly read pages on the chapter. The skin in perimenopause is doing four things at once — losing collagen, losing oestrogen-supported hydration, picking up reactivity, and gaining hyperpigmentation. The protocol is barrier-first. Lipid-rich moisturisers replace the lighter formulas of the thirties. Retinoids continue but are paced. Alpha hydroxy acids are typically reduced or replaced with polyhydroxy acids. Daily SPF becomes critical, not optional. The page is written without the panic copy that surrounds menopausal skin in most beauty media. The skin is changing, not failing.

A note on cumulative protocols

The chapter is built on the premise that skin behaves as a cumulative organ. The skin you have today is the result of the last six weeks of decisions, the last six months of climate, the last six years of sun exposure, and the last six decades of genetics. No single product, no single technique, no single ingredient acts in isolation. The protocols on this chapter are therefore time-based, not event-based. They prioritise consistency, paced introduction, and patience, because the skin that improves does so on a calendar of weeks and months, not minutes. The reader who takes nothing else from this chapter should take that.

How the chapter relates to the rest of the network

The skin chapter sits inside the Beauty Edition, which sits inside the HowTo Network — six editions covering Home, Food, Beauty, Travel, Tech, and Family. The methodology is the same across every edition: protocols over products, dimensions over categories, expert voices written in the clinical-warm register. The skin chapter cross-references the makeup, hair, and body chapters of the Beauty Edition, and the wellness chapter of the Family Edition where the topic crosses into hormonal health. We do not duplicate content across editions. Each edition covers its own surface, its own techniques, and its own protocols, and the cross-network links exist for the reader who wants to follow the through-line of a topic across surfaces.

The chapter's expert team

The skin chapter is led by Nelly Whitcombe, the Beauty Director of HowTo Beauty Edition. Nelly trained as a chemist before moving into beauty editorial, and the chapter carries her register: precise, warm, and refusing to oversell. She is supported by a team of named contributors — formulation chemists, board-certified dermatologists who consult on the medical edges of the protocols, makeup artists who understand how skincare reads under foundation, and longstanding beauty journalists who have watched the industry through more cycles than most. Every L3 page on the chapter carries the contributor's byline. No page is anonymous. Authority is named.

Closing note

If you are new to the chapter, start with Routine. If you are experienced, start with Ingredients. If you are returning to skincare after a long pause, start with Skin Type. If you are in a decade that is changing, start with By Age. The chapter is built so that any of those entry points is a complete, self-contained beginning. Read what you need. Ignore what you do not. Come back when the skin shifts, because the skin will shift. The protocols will be here.
