Standard testing uses one or two liquid additions. We ran three sequential insults to simulate real overnight use. After the first insult, products performed similarly. After the third, one product returned 5 grams more liquid to the surface than its competitor — a difference invisible in standard testing but decisive for consumer experience.
Rewet Benchmark Delta
After the third liquid insult, the rewet gap became a 5-gram chasm.
Key Result
5g
rewet difference after third insult — invisible in standard tests
