Greater radiance and improved-looking crow’s feet by Week 8.
Independent expert grading documented progressive improvement in eye-area radiance and crow’s-feet appearance, supported by strong participant perceptions of brighter, smoother, more rested-looking eyes.
Expert grading, n=31.
Participant perception, n=31.
Versus baseline, expert-graded radiance improved 14.51% at Week 6 and 20.21% at Week 8.
Expert grades quantify visible appearance; participant percentages report self-perception. These results are presented separately so each claim keeps its proper evidence source.
The strongest substantiation is expert-graded visible appearance.
Expert-graded appearance (n=31)
| Expert endpoint | Week 6 | Week 8 |
|---|---|---|
| Radiance | 14.51% improvement; 67.74% improved; p<0.001 | 20.21% improvement; 87.10% improved; p<0.001 |
| Crow’s-feet appearance | 5.49% improvement; 29.03% improved; p=0.001 | 9.15% improvement; 41.94% improved; p<0.001 |
Lower grades indicate improvement.
Scope of instrumental support
| Instrument endpoint | Finding | Interpretation |
|---|---|---|
| Corneometer hydration | Immediate -9.11%; p=0.049; Week 6 -5.98%; p=0.248; Week 8 -1.71%; p=0.734 | Did not substantiate improved hydration |
| Glossymeter shine | Immediate -29.62%; p<0.001 | Did not substantiate increased shine |
| Visioscan SEw wrinkles | Week 6 +7.63%; p=0.452; Week 8 -2.92%; p=0.741 | Week 8 favorable direction; not statistically significant |
The report therefore leads with expert-graded radiance and crow’s-feet appearance, not instrument hydration, shine, or wrinkle claims.
