How we pick a dupe

A product only qualifies if it (1) is in the same category, (2) costs less, and (3) shares the effective actives of the original — ingredients dosed at or above the published concentration threshold in our methodology. Underdosed or undisclosed actives don't count toward a match. The grade is computed from those thresholds, so a cheaper dupe can out-grade a pricier "original."

Based on published concentration thresholds and formulation science. Our algorithm predicts likely efficacy — it does not test the product. Individual results vary. Not evaluated by the FDA. Dupe matches are based on shared actives and published dosing thresholds, not side-by-side testing — formulas, textures, and tolerability still differ.
