About Similarity Scores

Our similarity score compares product formulas based on shared active ingredients, hero ingredients, and overall formula composition. A higher score means a more similar formula.

70%+ - High match
40-69% - Medium match
<40% - Low match

Note: Similarity is based on WIMJ's formula analysis (actives + overall formula similarity). Ingredient concentrations are estimated; products aren't lab-tested. A similar formula doesn't guarantee the same texture or feel.
