Skin MI and EI were measured using a Mexameter MX18 (Courage+Khazaka electronic GmbH, Köln, Germany). Mexameter uses a narrow-band reflectance spectrophotometric measurement, which is characterized by a circular sensor array of 16 light sources with three different wavelength ranges corresponding to melanin and hemoglobin, suited for skin tone analysis. This machine has a built-in elastic spring in the sensor head to minimize measurement error caused by unnecessary excessive pressure during the process of measuring skin reflection color. The results were expressed as MI and EI within 1 s of contact with the skin.
