Visible light (VL) has been shown to increase tyrosinase activity and induce immediate erythema in light-skinned individuals and long-lasting pigmentation in dark-skinned individuals. Tinted sunscreens (TSs) formulated with iron oxides (IOs) and/or pigmentary titanium dioxide (PTD) provide functional and cosmetic benefits and are a safe, effective, and convenient way to protect against both UV and high-energy VL. We conducted an analysis of over-the-counter TSs with the objective of investigating the factors that influence consumer preference when choosing TS depending on underlying skin tone. Descriptive data for each product were collected from an online supplier that provides reviewer information. The top 10 most helpful reviews were analyzed and coded by a consensus qualitative coding scheme, which included positive and negative descriptors in 5 major categories. Most products provided only one color shade, and tone incompatibility was the most commonly cited negative feature, with the vast majority of these comments being from consumers of dark skin tones. Top recommended products corresponded with increased shade options, indicating the dearth of shade diversity in products to be a potential area of improvement in tinted sunscreen options.
可见光(VL)已被证明可以增加酪氨酸酶的活性,并在浅色皮肤个体中引起即时红斑,在深色皮肤个体中引起持久的色素沉着。用氧化铁(IO)和/或颜料性二氧化钛(PTD)配制的有色防晒霜(TS)提供了功能性和美容效益,是一种安全、有效和方便的方式,可以同时预防紫外线和高能 VL。我们对非处方 TS 进行了分析,目的是研究根据基础肤色选择 TS 时影响消费者偏好的因素。从提供评论者信息的在线供应商处收集了每个产品的描述性数据。通过共识定性编码方案对前 10 名最有用的评论进行了分析和编码,该方案包括 5 个主要类别中的正面和负面描述符。大多数产品只提供一种颜色,色调不兼容是最常被引用的负面特征,其中绝大多数评论来自深色皮肤的消费者。被推荐的顶级产品对应着更多的色调选择,这表明产品色调的多样性不足是有色防晒霜选择中一个需要改进的潜在领域。
