Outcome Measures
Primary Outcomes (1)
L* measured using CM2600D
L\* (Luminance) - represents lightness/darkness values of luminosity indices (total quantity of light reflected). L\* is measured using spectrophotometer CM2600D, which measures the spectral reflectance in the visible wavelength range of 400nm to 700nm as the ratio of the power of the net total reflected light over total incident light. The colour values of L\*a\*b\* are calculated from the spectral reflectance. * Manufacturer Name: Konica Minolta * Measurement Range: L\* 0 - 100 * Efficacy Direction of L\*: Higher is better
0 - 6 weeks
Secondary Outcomes (3)
a* measured using CM2600D
0 - 6 weeks
Skin hydration measured using Corneometer CM825
0 - 6 weeks
Skin barrier function (Trans-Epidermal Water Loss [TEWL]) measured using Tewameter TM300
0 - 6 weeks
Other Outcomes (1)
Stratum corneum biomarkers of skin brightening
0 - 6 weeks
