Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Anti-wrinkle efficacy will be assessed in the periorbital regions wrinkles using DermaTOP. Parameters measured: Rz and Ra, representing mainly the rough structure (Rz) or the finer skin structure (Ra). | 8-weeks |
Secondary
| Measure | Time frame |
|---|---|
| Change from baseline in ceramides by Raman Spectroscopy [a.u.] on a subgroup of n=12 subjects per test product group after 2, 4 and 8 weeks | 8-weeks |
| Change from baseline in skin firmness by Cutometer [mm] after 2, 4 and 8 weeks | 8-weeks |
| Change from baseline in skin elasticity by Cutometer after 2, 4 and 8 weeks | 8-weeks |
| Change from baseline in skin hydration (assessed on skin capacitance by Corneometer [a.u.]) after 2, 4 and 8 weeks | 8-weeks |
| Change from baseline in skin barrier function (assessed on transepidermal waterloss by Tewameter [g/(m²h)]) after 2, 4, 8-weeks | 8-weeks |
| Change in Image grading (Photodocumentation via USR-Clip) for skin radiance (3 trained graders will rank each pair of images in a blinded fashion) after 2, 4 and 8 weeks | 8-weeks |
| Change in wrinkle scores (Photodocumentation via USR-Clip) for anti-wrinkle efficacy (3 trained graders will rank each pair of images at the area of the crow feet's in a blinded manner) | 8-weeks |
| Subjective Evaluation of product traits assessed via questionnaire after 2, 4 and 8 weeks | 8-weeks |
