Neal's Yard Remedies · Ardeo Eau de Parfum 50ml

Why this score

Three independent Greenlens lenses read the same 32 ingredients and land 34 points apart. That gap is not an error. Each lens asks a different question, and this page shows every answer, ingredient by ingredient, blended into nothing.

How well-studied are these ingredients?

Data coverage · Robust

28/32

Our sources have reference data on 28 of 32 listed ingredients; 4 are uncharacterized in our data — a gap, not a clean bill. Our sources can only speak to ingredients they recognize — either flagged by an authority or known to be a common, well-characterized ingredient. An uncharacterized ingredient is a gap in our data, not a clean bill of health: a quiet safety scan over ingredients we can’t place is a weaker signal than one over ingredients we can.

Uncharacterized in our data: CITRUS AURANTIUM PEEL OIL, ORGANIC, ORGANIC ORIGIN, FROM ESSENTIAL OILS.

Three lenses, one ingredient list

Greenlens Ingredient Scan

Independent

66Fair

The regulatory baseline. Follows EU cosmetic law: prohibited and restricted ingredients cost points, and allergen labelling is capped so it cannot tank a score on its own.

Flagged 27 of 32 ingredients: 1 restricted, 1 of concern, 25 regulated allergens.

Greenlens Precautionary Screen

Independent

100Excellent

The strict lens. Flags any ingredient with a listed hazard trait (SIN List, IARC, Prop 65), even when regulators still permit it.

No listed hazard traits recognized among 32 ingredients.

Greenlens Tolerance Screen

Independent

94Excellent

The lenient lens. Trusts dose and regulation: permitted ingredients kept within their legal caps are tolerated, and only genuinely prohibited substances take a big hit.

Flagged 1 of 32 ingredients: 1 restricted (within-limit).

These lenses disagree. A split of 34 points crosses our disagreement threshold (20). We keep every verdict and never average them; the table below is where the split comes from.

Coverage & match quality

3 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.

The overall ring on the product page is the weighted mean of the four pillars using your weights, computed fresh on every visit and never stored. How each lens's reference lists were built, penalty by penalty, is on the methodology page.
