Are DEET or other insect repellents safe to be used with sunscreen?
DEET 或其他驱虫剂是否可以安全地与防晒霜一起使用？
According to the U.S. Centers for Disease Control and Prevention (CDC), it is fine to use these products together. The CDC advises that people should apply sunscreen first and insect repellent second. In general, CDC recommends use of separate insect repellent and sunscreen products. However, the CDC also notes that a sunscreen’s SPF level may decrease when a DEET-containing insect repellent is applied after sunscreen, so people may need to reapply sunscreen more frequently if using the products in combination.
根据美国疾病控制与预防中心 (CDC)，可以一起使用这些产品。CDC 建议人们应该首先涂敷防晒霜，然后使用驱虫剂。一般来说，CDC 建议分开使用驱虫剂和防晒霜产品。但是，CDC 还指出，如果在防晒霜之后使用含 DEET 的驱虫剂，则防晒霜的 SPF 水平可能会降低。因此两种产品一起使用时，可能需要更频繁地重新涂抹防晒霜。
