How we rank.

Every ranking on Rank.Beauty is the output of a written rubric — not a popularity contest, and not a sponsored listicle. This page documents the rubric, the data behind it, and the editorial checks we run before a product is published.

What a ranking means

When a product is ranked № 3 in Face Serums, that number reflects a composite score, not a single metric. The score is deterministic: the same inputs always produce the same rank. When we update data, the rank can move — we log the date on the product page and in the Article schema.

The scoring rubric

Each product is scored on four weighted dimensions:

1. Ingredient efficacy (40%) — Does the formula contain actives at concentrations supported by peer-reviewed research for the claimed benefit? Filler, proprietary blends at low percentages, and duplicative actives are penalised.
2. Review signal (30%) — A blend of review volume and distribution, not just mean rating. A 4.6★ product with 12,000 reviews beats a 4.9★ product with 80 reviews. We normalise across retailers and flag suspicious patterns (bursts, incentivised batches) before ingesting.
3. Ingredient transparency (15%) — Brands that publish full INCI, concentration of headline actives, and pH where relevant score higher. Opaque formulas lose points regardless of marketing.
4. Editorial review (15%) — A human editor reads the formulation, cross-checks the claims against dermatology sources, and flags issues (sensitisers, conflicts with common routines, allergen risk). This is where a formally strong product can still get demoted for a real-world-usability problem.

A ranking is a falsifiable claim. If the inputs change, the rank changes — and we show you when they did.

Data sources

We ingest public catalog data (ingredients, price, retailer availability) from Amazon and brand websites. Review data is aggregated from the retailers listed on each product page. Clinical references come from peer-reviewed dermatology journals cited in our trend and ingredient pages. We do not accept payment for placement.

Update cadence

Rankings are recomputed on every data refresh. Product pages and trend articles display a visible Updated date; the same date is written into the JSON-LD dateModified field so search engines see the freshness signal without us asking for it. We typically refresh rankings weekly, with a full editorial review per quarter.

Affiliate disclosure

Rank.Beauty earns a commission when readers purchase through the links on product pages, at no cost to the reader. Commission has no effect on ranking position or editorial review. The affiliate relationship is disclosed on every product page and in our About page.
