INTRODUCTION
The impact of ultraviolet (UV) light on the skin is well-established to have both immediate and delayed effects with increasing awareness of the impact of visible light (VL) on the skin with regard to photoaging and dyspigmentation. The effects of VL disproportionately impact the skin of color with regard to discoloration of the skin leading to guidelines for photoprotection that include the use of iron oxides in sunscreen products that impart a tint.
METHODS
Commercially available sunscreen products found in the suncare and sun protection displays at local stores, pharmacies, and grocery stores were cataloged, and ingredients were reviewed for the presence of iron oxides.
RESULTS
Of the 410 commercially available sunscreen products cataloged, 1.7% of facial sunscreen products available offered iron oxides, and 0.5% of non-lip products offered shade matching.
CONCLUSION
With only 1.7% of commercially available facial sunscreen products offering iron oxides in addition to traditional broad-spectrum UV protection, there is a clear gap in the market for iron oxide-containing sunscreen products to meet the photoprotection needs for the skin of color.
引言
紫外线（UV）对皮肤的影响已得到充分证实，既有即时效应，也有延迟效应。随着人们对可见光（VL）对皮肤在光老化和色素沉着方面影响的认识不断提高，VL的影响也日益受到关注。就皮肤变色而言，VL对有色人种皮肤的影响尤为显著，这导致了光防护指南的出台，其中包括在防晒产品中使用能提供色调的氧化铁。
方法
对在当地商店、药店和杂货店的防晒及防晒保护展示区中发现的市售防晒产品进行编目，并审查其成分中是否存在氧化铁。
结果
在编目的410种市售防晒产品中，1.7%的面部防晒产品含有氧化铁，0.5%的非唇部产品提供色调匹配。
结论
在市售面部防晒产品中，除了传统的广谱紫外线防护外，只有1.7%的产品含有氧化铁，因此，含氧化铁的防晒产品在满足有色人种皮肤的光防护需求方面存在明显的市场缺口。
