Greenlens

Every rating source on one cosmetic, and where they disagree.

Is this safe for you? Greenlens shows what every public rater says, names who funds each opinion, and gives you one score whose weighting you control, never a blended number that hides the conflict.

Why this exists

The same moisturizer is “clean” in one app and “concerning” in another, and neither says why. So we put every opinion on one page, with who pays for each, and let you decide whose to trust.

What makes it honest

Disagreement stays visible

When EWG says "concern" and Yuka says "clean," we show the spread and name both instead of averaging them into silence.

Who pays is always shown

Every rating carries its funding model (nonprofit, ad-supported, subscription) so you can weigh the source, not just the score.

You own the weighting

Safety, environment, labor, packaging: slide them to what you care about. Computed live, never stored.

Greenlens Pro

Greenlens works without an account, and that stays true. Everything that is free today stays free, the shelf and the avoid-list included, and we will not move any of it behind Pro later. Ingredient watchlists are the one thing Pro gates today, and we are looking at whether that is the right call.
