Scientific Review Board for This Study
Independent Expert Review
To ensure the research met accepted scientific standards, the study findings were evaluated by an independent panel of dermatology researchers and clinicians. External review helps confirm that the methods used in testing are reliable and that the conclusions are supported by the collected data.
Several respected specialists contributed to the evaluation process:
Professor Charlotte Weber, MD – Head of Dermatology at University Hospital Zürich and a specialist in aging skin with more than 25 years of clinical experience. Her work has focused on understanding how skin structure changes over time and how different treatments influence those processes.
Marcus Bauer, PhD – Director of Dermatological Research at the Institute for Skin Biology in Munich. His research has contributed to improved laboratory techniques for measuring collagen activity in skin samples.
Dr. Laura Schmidt, MD, FAAD – Board-certified dermatologist specializing in non-invasive skin care treatments and long-term skin health management.
According to the review panel, the strength of the project lies in its structured evaluation process and the large number of products tested under consistent conditions.
Testing Methodology
Each product included in the study was assessed using a structured multi-step evaluation system designed to measure several aspects of skin performance.
The testing process included:
- Laboratory analysis of active ingredient concentrations
- Measurement of collagen-related activity in controlled skin sample studies over an eight-week period
- High-resolution 3D imaging used to monitor changes in wrinkle depth and surface structure
- Hydration levels measured at multiple intervals across a 24-hour period
- Dermatological compatibility assessed through controlled testing on volunteers with sensitive skin
- Long-term performance tracked across different age groups and skin types
This combination of laboratory measurements and clinical observation provided researchers with both objective and practical data about how the tested formulations performed.
Anonymous Product Selection
To maintain neutrality, all products used in the investigation were purchased anonymously through standard retail channels. No manufacturers were informed about the study in advance, and none were involved in the research design or analysis.
Anonymous purchasing is often used in independent product testing because it reduces the possibility of bias and ensures that the products evaluated match what consumers typically purchase in stores.
Why Transparency Matters
Independent testing is especially important in the skincare industry, where marketing claims can sometimes exceed what is supported by scientific evidence. Studies that clearly explain their methodology and review process allow both professionals and consumers to better understand how conclusions were reached.
As Professor Weber noted during the review process:
“Providing clear, research-based information helps people make better decisions when choosing skincare products.”
The goal of sharing this research is not to promote a specific product but to present findings from a large comparative analysis and explain how such studies evaluate effectiveness under controlled conditions.ccurate information based on real science—not marketing claims.
