Every claim we make traces back to one of these six studies, run by a third-party clinical research lab under dermatological or gynecological supervision. Here is each one — including the numbers that didn’t come out high.
6clinical studies on the products in the routine
291participants across all six

Studies 03–06 · Patch tests · 6–7 weeks
Four products, the hardest test for skin
A repeat-insult patch test (RIPT) keeps the product on the skin under a patch, nine times over three weeks, then once more after a ten-day rest — far more contact than daily use. A dermatologist supervised every participant.
