How the dupe finder works
Every product in the DermApproved database carries structured formula data: its hero actives normalized to canonical ingredient slugs, the skin types it suits, the conditions it targets, its form, and flags like fragrance-free and fungal-acne-safe. When you pick a target product, the finder scans every cheaper product in the same category and scores the overlap — shared actives carry the most weight (45%), followed by skin-type fit, condition coverage, matching form, and flag agreement.
Only candidates that clear a 40% overlap and share at least one hero active make the cut, because a "dupe" with none of the same working ingredients is just a different product in similar packaging. And when nothing in the database genuinely matches, the tool says so instead of stretching — some formulas really are uncommon, and pretending otherwise helps nobody.
Common questions
What actually makes a product a real dupe?
A real dupe shares the same hero actives at broadly similar strengths — the ingredients doing the work, not just the claims on the box. Two creams that both promise "plumper skin" aren't dupes; two creams built around the same retinoid, the same peptides, and a similar base are. That's why this tool matches on canonical ingredient data instead of marketing language.
Is a cheaper product automatically a worse product?
No — a surprising share of a luxury price tag pays for packaging, fragrance houses, and advertising rather than the formula. Drugstore and indie labs buy many of the same raw actives from the same suppliers. Where premium products do sometimes earn their price is in texture, stability work, and clinical testing, which is exactly what a match score can't see.
When is a dupe genuinely not worth it?
Delivery systems and sunscreens are the two big traps. An encapsulated retinoid or a time-release vitamin C behaves differently from the same ingredient dumped in a basic base, and two SPF products with different filter systems are not interchangeable at all. If the original's whole selling point is how it delivers an active, treat any dupe claim with extra skepticism.
How is the match percentage calculated?
It's a weighted overlap score: shared hero actives count for almost half, then skin-type fit, the conditions each product targets, whether the forms match, and agreement on formulation flags like fragrance-free and fungal-acne-safe. Everything is computed from our database fields — nothing is hand-picked or sponsored.
Are the dupes shown here exact copies of the original?
Never — think close relatives, not clones. Even a 90% match can differ in active concentration, pH, preservative system, and how it feels on skin. Read both full reviews before switching, especially if the original is something your skin already tolerates well.
