Every "best of" list online begs one question: who paid for this? On this desk, the answer is no one. Products are bought at retail, scored against a fixed published rubric, and no brand sees a word before you do. This page explains — in full, with nothing held back — exactly how a review here is made.
It is the single rule this review desk is built on, and the reason it exists at all. A recommendation here cannot be bought — not with money, not with gifts, not with access. The following commitments are not aspirations; they are the operating rules every review must satisfy before it publishes.
If a product is recommended here, it is because it earned the recommendation under testing — full stop. There is no second, commercial reason hiding behind the first.
Every product, in every category, is judged against the same fixed standard — not against the trend of the season and not against whatever the brand wants emphasized. Each criterion is scored from 0 to 10, then weighted to produce a single score out of 10, reported to one decimal. Here is what each one measures, and why it carries the weight it does.
The quality of the clinical data for each active at the concentration actually used — not the headline claims a brand makes for an ingredient in the abstract. A well-studied molecule under-dosed earns little here. Weighted heaviest because evidence is the whole point: it is the difference between a treatment and a hope.
Actual concentration, delivery system, pH, stability, packaging, and the supporting cast of ingredients. A brilliant active in an unstable, badly buffered, or air-exposed formula is a wasted active. This is where elegant marketing and honest chemistry most often part ways — so it is weighted second.
Irritation and sensitization risk, and suitability for the drier, more reactive, barrier-fragile skin common after 40. The strongest formula is useless if your skin can't keep using it. Weighted deliberately high here because tolerability is what determines whether a product is abandoned in week two — the most common reason a routine fails.
Texture, finish, scent, and the daily friction of using it — the unglamorous truth that the best skincare is the routine you'll still be following in a year. A serum that pills, stings, or feels unpleasant gets left in the drawer. Adherence is efficacy by another name, which is why it earns its own weight.
Cost per use weighed against what you actually get — not sticker price in isolation. A £15 formula can out-value a £150 one, and frequently does. Weighted lightest on purpose: price should inform a recommendation, but it must never outrank whether the product works and whether your skin can tolerate it.
| Evidence | 30% | |
|---|---|---|
| Formulation | 25% | |
| Tolerability | 20% | |
| Elegance | 15% | |
| Value | 10% |
Bars are proportional to weight. The total is always 100%, and the formula never changes mid-category.
The simplest way to keep a review honest is to pay for the product like everyone else. That is the default here, and the exceptions are narrow and always disclosed.
The overwhelming majority of what is tested on this desk is purchased at full retail, from the same shelves and websites you would use. There is no brand portal, no preferential pricing, and no arrangement under which a company supplies products in exchange for coverage. When a product is bought, the brand usually has no idea it is being tested until the review is live.
Occasionally an unsolicited PR sample arrives unprompted. When one is used in a review, two things are true without exception:
Brands cannot send a product to be reviewed as a transaction. Mailing in a box does not buy a place on the desk, a ranking, or a kinder reading. If a sample isn't worth testing on its merits, it isn't tested.
If you ever see a product praised here, assume it was bought — and if it wasn't, you'll be told so in the first paragraph.
Skincare results are slow by nature — collagen change in particular is measured in months, not days. A protocol that rewards a first-week glow would mislead the very readers this desk is written for. So testing is deliberately patient.
Each formula is used consistently for at least eight weeks before it earns a score. That is long enough to see real texture, tone, and tolerability — and long enough to catch the products that look promising at first and disappoint by week six.
Across a category, the full field is tested over roughly six months. This captures seasonal shifts, packaging that degrades over time, and the slow-building results — firming, pigment, fine lines — that a short trial would miss entirely.
Where a product is panel-tested, it goes on a matched volunteer panel of women aged 41 to 63 — chosen so findings reflect mature, peri- and post-menopausal skin, not a 25-year-old's. The relevance is the point.
Trust requires knowing how the lights stay on. Here is the whole of it, with no euphemisms.
Some links on the review pages are affiliate links. If you buy through one, this site may earn a small commission — at no additional cost to you; you pay the same price you would have paid anyway. That is the second, minor source of funding behind the reviews. It comes with three hard limits:
Eighteen years of clinical dermatology — and tens of thousands of patient consultations — are the foundation behind these reviews. The reviews are not a business that needs you to buy anything, which is exactly why they can afford to tell you not to.
Any relationship that could reasonably be seen to colour a judgement is disclosed at the top of the relevant review — a received sample, a brand connection, a speaking engagement, anything. Where a genuine conflict exists that disclosure alone can't neutralize, the product is not scored.
A handful of products in each category earn a badge. They are not decoration — each one answers a specific question, so you can find the right product for your skin, not just the top of the table.
The single highest weighted score — the product that best balances evidence, formulation, tolerability, elegance, and value. If you want the strongest all-rounder and your skin tolerates the active, this is where to start.
Not the cheapest, but the best ratio of results to cost. Often a quietly excellent formula at a fraction of the prestige price — proof that a high price tag and a high score are very different things.
The product that delivers real results with the lowest irritation and sensitization risk on the panel. Awarded with reactive, barrier-fragile, and post-menopausal skin specifically in mind.
The forgiving, dependable workhorse — the formula handed to most patients first because it pairs solid efficacy with the kind of everyday usability that keeps a routine going for years.
Formulas change, prices move, and new evidence arrives. A recommendation that was right two years ago can quietly become wrong. So reviews are maintained, not abandoned.
If a product appears to have been reformulated or repriced since a review published, please let us know — reader notes are one of the most reliable ways reviews get flagged for re-testing.
