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.
