If you are applying a sunscreen and a bug repellent, first apply the sunscreen, and then apply the repellent. If you are using a product that combines both a sunscreen and a repellent in the same bottle, you'll need to reapply the sunscreen separately because it may need to be reapplied more frequently than the repellent.

Follow the application and dosing instructions for each product as listed on their labels.

The American Academy of Pediatrics (AAP) does not recommend using that products that combine a sunscreen with DEET in one product on children. Sunscreen should be applied every 2 hours to help prevent sunburn, but DEET is typically used once a day in children.

Keep in mind that reapplying the combination product too often may lead to side effects due to the repellent.

Swimming or sweating may lessen the time that these products are effective and a reapplication may be needed. Always follow the package directions.

The EPA also has an Insect Repellent Finder tool to help you determine product options for you or your child. Always follow the product labeling or ask your doctor for recommendations.
