Abstract

Background/aims: Two types of skin reflectance instruments are available nowadays for the determination of skin color: a tristumulus colorimeter (Chromameter from Minolta) using the CIE L*a*b* color system and the narrow-band simple reflectance meters (DermaSpectrometer from Cortex and Mexameter from Courage-Khazaka) using the erythema/melanin indices. The purpose of thisstudy was to compare the capabilities of the three instruments (sensitivity, repeatability and correlation) in vitro and in vivo. Methods: Comparative color measurements were carried out first in vitro onstandardized color charts and subsequently in vivo on different skin areasin human volunteers. Skin color changes induced by various physico-chemical treatments were also quantitatively evaluated with the three instruments. Results: The in vitro and in vivo repeatabilty as well as the sensitivity of the three instruments are rather good. Erythema and skin blanching couldbe readily quantified by the increase of the a* parameter and of the erythema indices of the simple reflectance meters. Natural UV tanning and artificial chemical tanning could be measured by the decrease of L* and increase of b* and of the melanin indices. Conclusion: The Chromameter and the two narrow-band reflectance instruments were able to characterize skin color and to quantify small skin color changes. Moderate to high significant linear correlations could be establishedbetween the CIE L*a*b* color parameters and the erythema/melanin indices.
