How To Run A Fair 30-Day Trial
A guarantee only helps if you can tell whether something worked.
Create a baseline
Take a photo of your skin in the same light and note digestion for a few days before you start.
Change one thing
Do not start a new skincare routine, diet and supplement at once.
Track simply
Spend a minute a day on notes, and repeat the photo weekly.
Read the fine print
Confirm when the clock starts, whether bottles must be returned and any fees. See our refund page.
Decide at day 30
Compare notes and photos with your baseline. If you see nothing, request the refund inside the window.
