[ 03 · HOW_WE_MATCH ]

How we find a dupe

01

Same product type

Serums are compared with serums, from the products we've scored.

02

Actives count most

S and A-grade actives weigh up to 30 times more than water, glycerin or thickeners. A dupe must share at least one key active.

03

30% match or more

Below that it isn't a dupe. Same brand and renamed versions of the original are left out.

A label lists ingredients, not amounts. Two products can share every ingredient at different strengths, so a high match means a similar formula, not a guaranteed identical result.
