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
We built Greenlens after noticing something annoying: the same moisturizer can be “clean” in one app and “concerning” in another, and neither tells you why. Both are right, in their own way, but they just measure different things and get paid by different people. So instead of picking a winner, we put every opinion on one page 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 is coming
Your shelf synced across devices, watchlists for the ingredients you avoid, and an alert when a rater changes its mind about something you own. Greenlens works without an account, and that stays true. An account is optional and only adds sync.
