Anti-wrinkle efficacy will be assessed using DermaTOP. Parameters measured: Rz and Ra, representing mainly the rough structure (Rz) or the finer skin structure (Ra).
Time frame: 12 weeks
Skin barrier function
Change from baseline in skin barrier function (assessed onTransepidermal water loss (TEWL) by Tewameter \[g/(m²h)\]) after 6 and 12 weeks
Time frame: 12 weeks
Skin hydration
Change from baseline in skin hydration (assessed on skin capacitance by Corneometer) after 6 and 12 weeks
Time frame: 12 weeks
Skin firmness
Change from baseline in skin firmness (assessed by R0 (Uf) by Cutometer \[mm\]) after 6 and 12 weeks
Time frame: 12 weeks
Skin elasticity
Change from baseline in skin elasticity (assessed by R7 (Ur/Uf) by Cutometer) after 6 and 12 weeks
Time frame: 12 weeks
Wrinkles and fine lines
Change from baseline for wrinkles and fine lines (assessed on VISIA-CR Image analysis) after 6 and 12 weeks
Time frame: 12 weeks
