Expert grading, n=33; p<0.001.
Brighter-looking eyes, with visible results that deepen over time.
Expert grading documented significant Week 6 improvements in the appearance of dark circles, puffiness, and peri-orbital lines.
Expert grading, n=33; p<0.001.
Participant perception, n=33.
Visible improvement progressed through Week 6.
Immediate performance
Fifteen minutes after the first application, Cutometer readings showed an 8.31% improvement in R0 firmness (n=27; p=0.039) and a 15.16% improvement in R5 elasticity (n=27; p=0.001). These immediate instrument findings are presented separately from the Week 4 and Week 6 expert-graded appearance results.
Selected Week 6 participant perceptions
A signed final source reports the six-week expert-graded eye-area endpoints.
Expert-graded mean change from baseline
| Expert endpoint | 15 minutes | Week 4 | Week 6 |
|---|---|---|---|
| Dark circles / discoloration | -10.20%; n=33; p<0.001 | -31.95%; n=32; p<0.001 | -38.10%; n=33; p<0.001 |
| Puffiness / bags | -8.67%; n=33; p<0.001 | -16.55%; n=32; p<0.001 | -23.12%; n=33; p<0.001 |
| Peri-orbital fine lines | -1.18%; n=31; p=0.161 | -4.57%; n=30; p=0.001 | -8.82%; n=31; p<0.001 |
Lower grades indicate improvement. n is shown for every endpoint and timepoint.
Instrumental timing context
| Cutometer parameter | 15 minutes | Week 4 | Week 6 |
|---|---|---|---|
| R0 firmness | -8.31%; p=0.039 | +32.00%; p<0.001 | +35.17%; p<0.001 |
| R5 elasticity | +15.16%; p=0.001 | -15.74%; p<0.001 | -12.04%; p=0.005 |
R0 decrease and R5 increase indicate improvement. The favorable Cutometer response was recorded at 15 minutes; Week 4 and Week 6 values are included for complete timing context.
Thirty-three participants completed the study. Two mild adverse events were recorded and no participant withdrew. Results apply to NeoTight Eye Serum under the reported six-week design.
