- 02Every active, separately.
All 1 actives checked against the clinical evidence: dose, form, and what the research actually shows.
- 03Then the formula as a whole.
Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "No hidden blends".
- 04Earned, not bought.
The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.
