With increasing awareness regarding the risks of sunburn, photoaging, and skin cancer, the use of sunscreens has increased. Organic and inorganic filters are used in sunscreen products worldwide. Concerns have been raised regarding the environmental effects of commonly used organic ultraviolet (UV) filters, including oxybenzone (benzophenone-3), 4-methylbenzylidene camphor, octocrylene, and octinoxate (ethylhexyl methoxycinnamate). Studies have identified UV filters such as oxybenzone, octocrylene, octinoxate, and ethylhexyl salicylate in almost all water sources around the world and have commented that these filters are not easily removed by common wastewater treatment plant techniques. Additionally, in laboratory settings, oxybenzone has been implicated specifically as a possible contributor to coral reef bleaching. Furthermore, UV filters such as 4-methylbenzylidene camphor, oxybenzone, octocrylene, and octinoxate have been identified in various species of fish worldwide, which has possible consequences for the food chain. As dermatologists, it is important for us to continue to emphasize the public health impact of excessive sun exposure and advise our patients about proper photoprotection practice, which consists of seeking shade, wearing photoprotective clothing (including hats and sunglasses), and applying appropriate sunscreens.

随着人们对晒伤，光老化和皮肤癌风险的认识不断提高，防晒霜的使用也有所增加。全球的防晒产品中都使用有机和无机过滤器。对于常用的有机紫外线（UV）滤光片，包括氧二苯甲酮（苯甲酮-3），4-甲基亚苄基樟脑，辛二烯和辛氧酸酯（乙基己基甲氧基肉桂酸酯），其环境影响已引起关注。研究已经在世界上几乎所有的水源中确定了紫外线过滤器，例如氧苯甲酮，辛二烯，辛酸酯和水杨酸乙基己酯，并评论说这些过滤器不易通过普通的废水处理厂技术去除。另外，在实验室环境中，已明确暗示氧苄酮可能是导致珊瑚礁褪色的原因。此外，紫外线滤光片，例如4-甲基亚苄基樟脑，氧苯甲酮，辛二烯和辛氧酸酯已在世界范围内的各种鱼类中得到鉴定，这可能对食物链产生影响。作为皮肤科医生，对我们而言，重要的是要继续强调过度日晒对公众健康的影响，并建议患者进行适当的光保护措施，包括寻求遮荫，穿着光防护服（包括帽子和墨镜）以及使用适当的防晒霜。
