Q+A · Glycolic Acid Exfoliating Toner

Why this score

Three independent Greenlens lenses read the same 15 ingredients and land 10 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

15/15

Our sources have reference data on all 15 listed ingredients. 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.

Three lenses, one ingredient list

Greenlens Ingredient Scan

Independent

90Excellent

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 1 of 15 ingredients: 1 restricted.

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 15 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 15 ingredients: 1 restricted (within-limit).

Every flagged ingredient, under every lens

Coverage & match quality

5 ratings · 1 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.
