• Background The actual skin colorimeters analyse reflect values from a limited number of broad spectral bands and consequently present limited reproducibility and specificity when measuring skin colour. Here, Antera 3D®, a new device which uses reflectance mapping of seven different light wavelengths spanning the entire visible spectrum, has been compared with Mexameter® MX‐18, an established narrow‐band reflectance spectrophotometer and with Colorimeter® CL‐400, an established tristimulus colorimetric instrument. Methods Thirty volunteers were exposed to a controlled ultra‐violet B light. Measurements with Antera 3D®, Mexameter® MX‐18 and Colorimeter® CL‐400 were done before treatment and after 2, 7 and 14 days. Results Antera 3D® showed to have a better sensitivity and specificity than Mexameter® MX‐18 regarding the melanin parameter. A similar sensitivity between Antera 3D® and Mexameter® MX‐18 was found for erythema determination and also for the Commission Internationale de l'Eclairage L*, a* and b* parameters between Antera 3D® and Colorimeter® CL‐400. Good correlations were observed for all the parameters analysed. Repeatability of Mexameter® MX‐18 and Colorimeter® CL‐400 values were lower than that of Antera 3D® for all the parameters analysed. Conclusion Antera 3D®, such as Mexameter® MX‐18 and Colorimeter® CL‐400, are robust, sensitive and precise equipment for the skin colour analysis.
