6 ratings · 2 of 4 axes
- Some ratings rest on an automatic match that has not been human-reviewed.
- Fewer raters reach smaller-brand products, so a missing rating is not a clean bill of health, only a gap.

How this score is built
no black box
How this score is built
We don't rate products ourselves. We collect what each public rater already says, put every scale on common ground, and keep the disagreements visible instead of averaging them away.
- 1
Collect each rater's own score
Every source keeps its native verdict for this product. We never invent a score for an axis a source didn't measure.
- 2
Normalize to 0–100, higher = better
Raters can use different scales and directions: some where a low number means safe, some where a high one does. We map them all onto one 0–100 axis and flip the ones that run backwards so the numbers are finally comparable.
- 3
Average per axis, but keep the spread
Scores on the same axis become one representative number (their mean). When raters split by 20+ points we flag it and keep every rater's number. A disagreement is never blended into silence.
- 4
Your weights make the overall
The ring is the weighted average of the four pillars using your weights. It's computed fresh every time and never stored, so there's no hidden “objective” default.

Raters split here, so this 75 is a midpoint, not a consensus. The spread stays on the “every rater” list above.
Why the safety score
Greenlens Ingredient Scan
Independent · EU regulatory reference
78/100
Flagged 2 of 21 ingredients: 1 restricted, 1 of concern.
- RetinolEU Cosmetics Regulation Annex III (restricted)−10
- Fragrance / Parfum (undisclosed)Common transparency/sensitization concern (not a regulatory ban)−12
Starts at 100; 19 other ingredients carried no recognized regulated hazard. Absence of a flag means no regulated hazard was recognized — not proof of safety. This is one lens; see where raters disagree above.
Why this score
Every ingredient, under all three lenses
The Scan is one opinion. The strict and lenient lenses read the same list and land 22 points apart. See what each one flags, and what it costs.
