Chromameter Technology and Macrophoto Assessment:
- 30 subjects undergo Chromameter assessments and visual assessments of skin luminance on site at our testing center. This measures chromaticity, tristimulus values, color difference and correlated color temperature.
- Active Phase: Subjects are given an instruction sheet, calendar and one of the test products to be applied to their left inner upper arm. Results are recorded within one hour of application at various stages during the 6 weeks. They then are re-assessed after the 6 week treatment phase.
