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.
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.
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).
CSKIN could serve as an alternative in the assessment and follow-up of skin disease featuring with facial hyperpigmentation.
色素沉着障碍是皮肤科最常见的皮肤问题之一。非侵入性仪器的出现为评估色素沉着和肤色提供了一种方便、客观和可重复的方法。本研究旨在比较 CSKIN 和 VISIA 在测量面部色素沉着方面的差异，并评估仪器分析与临床评估之间的相关性。
共纳入 80 例中国患者。使用 Canfield 的 VISIA 和 Yanyun Technology 的 CSKIN 拍摄和分析图像，并由 3 名皮肤科医生对面部色素沉着进行分级。
VISIA 分析的面部色素沉着区域的特征计数与 CSKIN 测量的棕色像素（r = 0.331，p < 0.05）和棕色百分比（r = 0.395，p < 0.0001）呈正相关。CSKIN 和 VISIA 测量的参数与皮肤科医生的视觉评分显著相关，VISIA 呈中度相关（r = 0.509，p < 0.001），CSKIN 与视觉评分的相关性略强（r = 0.653，p < 0.001）。
CSKIN 可作为评估和随访面部色素沉着性皮肤病的替代方法。
