Dihydroxyacetone and lawsone, in a vanishing cream base, applied to the skin was found to protect patients with erythropoietic protoporphyria against sunlight. The use of the same ingredients in a 50% isopropyl alcohol/water solution did not induce adequate light protection. The chemically induced ultraviolet light filter in the stratum corneum allowed these patients to change their lives from an "indoor" to an "outdoor" environment.
研究发现,将二羟基丙酮和紫铆因添加到雪花膏基质中涂抹于皮肤,可保护红细胞生成性原卟啉病患者免受阳光伤害。而在50%异丙醇/水溶液中使用相同成分,并未产生足够的光防护效果。角质层中化学诱导产生的紫外线滤光剂使这些患者能够从“室内”环境转变为“室外”环境,改变了他们的生活。
