The Science of the Sleuth

INCI Formula Deconstruction

We strip away the marketing fluff. Our AI reads the strict INCI ingredient deck, isolating the exact active molecules and core base structures that make luxury products effective.

Smart Functional Equivalency

We don't just look for identical names; we look for identical performance. Our engine matches the primary vehicle and identifies functional equivalents in the top 5 anchors—finding structural twins that perform exactly the same way.

Ruthless Quality Ranking

We ignore pretty packaging and marketing claims. Matches are aggressively filtered by chemistry alone. If a candidate doesn't share the same core architecture and matching active ingredient profiles, it is automatically rejected. You get scientifically validated alternatives, minus the luxury markup.
