What you get for taking part
Transport allowance
Paid to a bank account in your own name once you complete the visits. If you stop early, you are paid for the visits you did attend.
Skin measurements
Wrinkles, hydration, elasticity — measured on professional equipment before and after, and the readings are yours.
Subject Safety Management
Based on a collaborative network with specialized hospitals and medical professionals, we prioritize and manage the safety of trial participants.
IRB-approved only
Every study runs under a protocol approved by an institutional review board, with a safety contact available throughout.
A study only ever runs to the protocol that was approved
Before you take part, you are told in writing what will be measured, over how many days, and by what method. Nothing starts until you have agreed to it.
- Every
study we have run started only after institutional review board approval.
- 68%
of people who take part once apply for another study.
- On call
A safety researcher is reachable directly for the whole of the study.
Nothing starts without IRB approval
Every study follows a protocol reviewed and approved by an institutional review board.
Your data is used for the study only
What we collect is used to run the study and pay the allowance — nothing else.
You can stop at any time
Withdrawing from a study carries no penalty of any kind.
More detail on how participants are protected is on the introduction page, and the FAQ answers the questions we hear most.
Questions we hear most
