Abstract：
BACKGROUND: Tinted sunscreens not only shield against UV rays but also provide protection against visible light, as opposed to traditional sunscreens. Universal tinted sunscreens are marketed to complement all skin tones.
OBJECTIVE: To assess color match and subject satisfaction for 7 universal tinted sunscreens across various price ranges in all Fitzpatrick skin phototypes (SPT).
METHODS: Products A-G were applied at concentrations of 1 and 2 mg/cm2 on the dorsal arms of 30 subjects spanning SPT I-VI. Photography, colorimetry, and subject and investigator surveys were utilized to determine color match.
RESULTS: Using colorimetry analysis at the recommended 2 mg/cm2 concentration, two of seven products were identified as suitable matches for SPT I-II, while six out of seven were determined to be a good match for SPT III-IV. However, only one product was found to be a good match for SPT V-VI at the recommended concentration according to colorimetry results.
CONCLUSIONS: Universal tinted sunscreens do not provide an adequate color match for all skin phototypes, especially for individuals with very fair or very dark skin tones.

摘要：
背景：着色防晒霜不仅可以抵御紫外线，还可以抵御可见光，而不是传统的防晒霜。通用有色防晒霜上市，以补充所有肤色。
目的：在所有Fitzpatrick皮肤光型（SPT）的各种价格范围内，评估7种通用有色防晒霜的颜色匹配和受试者满意度。
方法:产品A-G以1和2mg/cm2的浓度应用于30名跨越SPTI-VI的受试者的背臂上。摄影,比色法,受试者和研究者调查用于确定颜色匹配。
结果：在推荐的2mg/cm2浓度下使用比色法分析，七个产品中的两个被确定为SPTI-II的合适匹配，而七分之六被确定为SPTIII-IV的良好匹配。然而,根据比色法结果,在推荐浓度下,只有一种产品与SPTV-VI匹配良好.
结论：通用着色防晒霜不能为所有皮肤照片提供足够的颜色匹配，特别是对于肤色非常白皙或非常暗的人。
