Our beauty desk receives more reader correspondence than any other. The questions are almost identical: how do I tell what is doing the work, what is worth the money, and what should I quietly stop buying?

This is the cornerstone guide that holds the rest of our beauty coverage together. It is built from nine years of newspaper-section experience, six months of running a single-active routine on three reviewers, and a stack of label-by-label comparisons we did not enjoy.

The structure is deliberate. We start with the four principles that survive every category, move into the actives we recommend by phase of routine, and finish with the places we see readers most often overspend or under-think.

We do not chase trends here. The category cycles a new 'breakthrough ingredient' approximately every nine months; the ingredients that survive ten years of cycling are the ones our coverage prioritises.

Where we cite an active, we cite the evidence baseline our reviewer used, not the marketing copy on the box. Where we recommend a product, it is one that survived a real routine for at least six weeks.

The summary

Beauty is the category where editorial discipline matters most and is practised least. This is the cornerstone reference our desk uses to evaluate every product we write about: four working principles, the actives that have evidence behind them, and the places where readers most often waste money.

In its favour

  • A single-active routine, run patiently, outperforms a six-step stack in almost every reader case we have followed.
  • Effective formulations exist at every price point; brand prestige correlates with packaging more reliably than with results.
  • Labelling regulations make ingredient hierarchy genuinely readable once you know what to look for.
  • Most categories have a clear 'good enough' tier that drugstores stock — paying more often buys experience, not efficacy.

Where it falls short

  • Marketing prefers narratives to ingredient lists, and most reviews follow the narrative.
  • Patch testing has fallen out of fashion at exactly the moment more readers are layering multiple actives.
  • Several popular actives are mutually antagonistic; combining them undoes the work of either.
  • Devices (LED masks, microcurrent units, hair tools) are the category where price-to-evidence ratio is worst.

Who it's for

  • — Readers building a routine deliberately for the first time.
  • — Anyone auditing an existing twelve-product routine they no longer remember the reasoning for.
  • — Readers shopping at the drugstore tier who want to know which products are genuinely doing the work.

Who should skip it

  • — You expect a single product to address multiple, unrelated skin concerns.
  • — You are looking for medical-grade dermatology guidance — that is your dermatologist's job, not ours.

Buying guidance

  • One active per phase of routine: vitamin C in the morning, a retinoid or chemical exfoliant in the evening. Add a third only after twelve weeks of stable use.
  • Concentration and formulation pH matter more than the named active. A 10% niacinamide that is poorly buffered is worse than a 5% that is not.
  • Buy the smallest size first. Effects on skin take six to twelve weeks to evaluate honestly.
  • Patch test on the inner forearm for three nights before applying any new active to the face.
  • Sunscreen is the only non-negotiable. Without daily SPF, every other active in your routine is fighting an uphill battle.
  • Devices: rent or borrow before buying. The price-to-evidence ratio is the worst in the category.

Alternatives we considered

  • Paula's Choice 2% BHA Liquid Exfoliant

    A category-defining BHA. Our default recommendation for first-time exfoliant users.

  • The Ordinary Niacinamide 10% + Zinc 1%

    The cheap, well-formulated entry point that survives most price-versus-evidence audits.

  • La Roche-Posay Anthelios UVMune 400

    The daily sunscreen our beauty desk reaches for. Filters are modern, finish is wearable, fragrance is restrained.

Reader questions

How many products should a routine actually contain?
Four to six is the sweet spot for most readers: cleanser, moisturiser, sunscreen, and one or two active treatments. Beyond that, the marginal benefit drops sharply and the chance of interaction rises.
Does price predict efficacy?
Loosely, and only above the very bottom tier. Above roughly the £25 / $30 mark for a serum, the additional cost almost always pays for packaging, fragrance, or marketing rather than additional clinical benefit.
Are devices like LED masks worth the money?
For most readers, no. The clinical evidence at the home-use power levels is thin, and the build quality of mid-priced devices does not justify the spend. We do not currently recommend any consumer LED device for purchase.
How long should we use a product before judging it?
Six to twelve weeks for most actives. Sunscreens and cleansers can be judged in days; serums and retinoids cannot.
What is the single highest-impact change for most readers?
Daily broad-spectrum sunscreen, applied at the volume actually recommended on the label. Nothing else in skincare has comparable evidence.

Editorial verdict

A defensible routine is short, patient, and built around evidence rather than narrative. The reader who arrives at month six with calmer skin is, almost without exception, the one who removed three products rather than adding two. Build the routine your dermatologist would not flinch at; ignore the rest.
