Can I use sunscreen with bug repellent, and get two-in-one protection?
Sunscreen-Repellent combination products are not recommended. According to Dermatologist Zoe D. Draelos, interviewed in the journal Drug Week, “Applying a combination product too frequently may pose the risk of insect repellent toxicity, but too few applications may cause photodamage from the lack of UV protection.” (Drug Week 2008). A Consumer Reports analysis determined that, “As for insect repellent with sunscreen, the two we tested for a report last June did not repel bugs especially well. A study published in 1997 showed that DEET can reduce a sunscreen’s SPF by up to one-third.” (Consumer Reports 2001). Additional scientific research is necessary before determining the safety and effectiveness of Sunscreen-Repellent combination products. If you are going to use both sunscreen and bug repellent: apply the sunscreen first and let it set-up for 15-30 minutes then apply your favorite bug repellent.
