Abstract Background Hyperpigmentary disorder is one of the commonest skin concerns in dermatology clinics. The availability of noninvasive instruments provided a convenient, objective, and reproducible methodology for the evaluation of pigmentation and skin color. The aim of this study is to compare CSKIN and VISIA in measuring facial hyperpigmentation, as well as to assess the correlation between the instrumental analyzing and clinical evaluation. Methods Eighty Chinese patients were enrolled. Images were taken and analyzed by VISIA from Canfield and CSKIN from Yanyun Technology, and the facial hyperpigmentation was graded by three dermatologists. Results Feature counts within the facial pigmented areas analyzed by VISIA showed positive correlations with brown pixels ( r = 0.331, p < 0.05) and brown percent ( r = 0.395, p < 0.0001) measured by CSKIN. The parameters measured by CSKIN and VISIA were significantly correlated with visual scores graded by the dermatologists, with VISIA presenting a moderate correlation ( r = 0.509, p < 0.001) and CSKIN a slightly stronger correlation with the visual scores ( r = 0.653, p < 0.001). Conclusion CSKIN could serve as an alternative in the assessment and follow‐up of skin disease featuring with facial hyperpigmentation.
