FAQ
Why is Skin Diligent launching this challenge?
This challenge is part of our research into skin longevity. In addition to sharing advice over a 10-day period, it allows us to collect strictly anonymous data on changes over time to feed into an observational study on the impact of simple daily habits on markers of perceived longevity.
A summary of the overall results will be shared in March.
IMPORTANT: No data that could identify you (surname, first name, email address, etc.) is used in the analysis: the results are aggregated and processed for research purposes only.
Can I join the challenge halfway through?
No. The challenge begins on 15th January and runs for 10 consecutive days. To validate your participation, you must follow all 10 days of advice and then retake the questionnaire at the end of the challenge. This continuity is essential to ensure the consistency of the programme and to enable reliable measurement of progress.
