Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Solar Lentigines Count	Solar lentigines count up to 13 weeks	up to 13 weeks
Secondary	Change From Baseline in Melanin Levels	This assessment was made using a narrowband re?ectance spectrophotometer (Mexameter MX18®, Courage-Khazaka, Germany). The measurement is based on absorption/reflection. The probe of the Mexameter® MX 18 emits three specific light wavelengths. A receiver measures the light reflected by the skin. As the quantity of emitted light is defined, the quantity of light absorbed by the skin can be calculated. The melanin is measured by two specific wavelengths (red: 660 nm and near infrared: 880 nm) chosen to correspond to different absorption rates by the pigments.; The quantification of melanin is presented as a value that varies from 0-999. The higher the value, the larger is the amount of melanin on the skin.	Baseline and up to 13 weeks
