How we find a dupe
Same product type
Sunscreens are compared with sunscreens, from the products we've scored.
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.
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.
