Systemic Absorption of Sunscreening Agents

Until recently, systemic exposure to sunscreen agents had also received relatively little attention in the medical literature. Agents such as benzophenones and octyl-methoxycinnamate can be detected in plasma and urine after topical application of sunscreen products.[10] Unfortunately, most of these studies were conducted with non-commercial sunscreen formulations or were performed at significantly higher doses than what the average consumer uses. Additional research is definitely needed to explore the absorption of active agents contained in commercial sunscreens used under normal conditions. Furthermore, studies assessing the risks (or benefits) of systemic absorption of various sunscreen agents in adults, children, and pregnant women are also warranted.
