Consider the ingredients.
Look carefully at what a product contains, within the context of its intended use.
Our approach
Clarity should have substance.
The Stemma Standard is our proposed approach to explaining product information. Its goal is to make the reasoning behind an assessment easier to understand.
THE STEMMA STANDARDThoughtful criteria.Clearer explanations.
Our framework is taking shape
What guides usMore understanding.
More understanding.
Less guesswork.
A number can be useful. But a number on its own doesn’t tell the whole story.
We’re developing criteria that consider ingredients, intended use and the information available about a product. A Stemma Score is intended to summarize that assessment, alongside an explanation of its limits.
Four guiding principles
What we want the Standard to stand for.
Value transparency.
Make the basis for an assessment understandable, with limitations presented clearly.
Respect the context.
Consider product category, purpose, and available information rather than treating every item as identical.
Keep improving.
Leave room for updated formulations, new information, and a methodology that evolves responsibly.
A look inside the app
Built to make the reasoning visible.
An early look at how the app could explain the Stemma Standard. The criteria and scoring framework have not yet been finalized or independently validated.
About the example scores
Meet the appExample Stemma Scores and product assessments are for demonstration only and are not verified product ratings. They are not certifications or guarantees of safety or effectiveness.
As we prepare for launch
Clear explanations come before confident claims.
We’ll share the criteria, their limits and the basis for assessments as the Stemma Standard is finalized.
