Evaluation of spots and skin individual typology angle (ITA) measured using a spectrophotometer/colorimeter CM-700D (Konica-Minolta) at T0, T28, and T56 (days) 2. Evaluation of skin radiance/skin brightness measured using a spectrophotometer/colorimeter CM-700D (Konica-Minolta) at T0, T28, and T56 3. Clinical evaluation of skin evenness complexion and whitening efficacy on Visia pictures measured using an improvement clinical scale (from 1: no variation to 4: remarkable improvement) at T28 and T56

Secondary

MeasureTime frame
1. Measurement of the variation of the levels of accumulated advanced glycation end products (AGE) measured using an AGE Reader mu of DiagnOptics Technologies B.V at T0 and T56 2. An evaluation of face digital pictures measured using means of Visia®-CR (Canfield Scientific) at T0, T28, T56 3.
