Should you use sunscreen or bug repellent first?

Sunscreen and bug spray are two staples you should have on hand, especially in the warmer months when we tend to spend more time outside. Sunscreen can help you prevent sunburns and skin cancer. Bug spray can help prevent itchy bug bites as well as potential diseases insects spread.

How you apply sunscreen and bug spray can help make sure each does its job and protects your health and well-being.

Should you put sunscreen or bug repellent on first?

When you’ll be outside in the sun, you should apply both sunscreen and bug spray. The order is important, too. The American Academy of Dermatology recommends putting your sunscreen on first followed by your insect repellent.¹ Be sure to let the sunscreen dry before applying your repellent.

Are sunscreen and bug repellent combo products a good idea?

Even though the idea of a two-in-one product sounds nice, the combo isn’t the best way to prevent bites and burns. The CDC says sunscreen needs to be applied more often than bug repellent, so it’s easiest (and most effective) to use separate products.²

How to use sunscreen and DEET repellents together

Many bug repellents contain DEET, and while it’s effective at reducing bug bites, it can actually make your sunscreen less effective.2 While you can still use both, you should apply sunscreen more frequently than you normally would if you also use a DEET-containing repellent. 

What kind of sunscreen is best?

Many dermatologists say the best sunscreen is the one you’ll wear every day. But the AAD says there are a few things you want your sunscreen to include:3 

• Broad-spectrum protection. This means it protects against UVA and UVB rays. Make sure your bottle specifically mentions this feature.

• SPF 30 or higher. Make sure your lip balm also has SPF 30 or higher.

• Water-resistant. No sunscreen is completely waterproof, but some hold up better in the water than others. Remember to reapply when you get out of the water, even if your sunscreen is water-resistant. 

Make sure your sunscreen checks all of the boxes before catching some rays.

How often should I put on sunscreen?

Before you head out, give yourself 15 minutes from applying sunscreen to heading outdoors. It takes your body a little bit of time to absorb the product, allowing it to work. 

Be sure to use enough sunscreen to actually protect your skin. The AAD says most adults will need about one shot glass full of sunscreen to properly cover all exposed skin.³ 

If you’re outside, you should reapply sunscreen every two hours. When you’re swimming or sweating, put a fresh application on after toweling or drying off. 

What kind of bug repellent is best?

While there’s no one “best” insect repellent, the American Academy of Pediatrics (AAP) recommends those that are approved and registered with the Environmental Protection Agency.⁴ 

There are several different ingredients used in insect repellents. Here are a few examples: 

• DEET
• Picaridin
• Oil of lemon eucalyptus 
• Citronella

It’s important to note that some products aren’t a good idea for small children and infants. The AAP says you should not use repellents with either oil of lemon eucalyptus or para-menthane-diol (PMD) on children younger than 3 years old.⁴ 

Read the label on the product and follow all manufacturer directions when you use insect repellent.

How often should I put on bug repellent?

You should reapply insect repellent according to the label on the product.
