What the numbers say
Start with what counts as a dupe here. Base ingredients that appear in nearly everything, like water and glycerin, are ignored. What we compare is whether the actives that actually do the work overlap, checked against both full ingredient lists. Only pairs that pass get a market price attached and published — those 390 pairs are this sample.
A high overlap count alone does not make a good dupe. Hyaluronic Acid tops the table below at 260 pairs (67%). That mostly proves the ingredient is common enough to appear at every price point. What matters is not how many ingredients overlap but which ones do.
For the same reason, not every luxury product has a dupe. Many of the products we compared are built around signature ingredients that budget formulas rarely carry, so they never reach the publishing bar. And even with the same actives, concentration and formulation still differ — each pair page shows that comparison in full.
Still, the reason this data exists is simple: price gaps that the ingredient list cannot explain show up often. 105 pairs held up even above ₩200,000, and half of the published pairs save more than 83%. By category, start where the gap is widest — Sheet mask at a 92% median.
