Sunscreen or Bug Spray First? The Ultimate Summer Showdown

Summertime is synonymous with sunshine, outdoor adventures, and… pesky insects. But when it comes to protecting ourselves from the sun and bugs, a common question arises: Should I apply sunscreen or bug spray first?

The answer isn't as straightforward as you might think. To understand the best approach, we need to delve into the science behind both products.

The Science Behind Sunscreen

Sunscreens work by absorbing or reflecting ultraviolet (UV) radiation from the sun, protecting our skin from sunburn and long-term damage. [1] These products contain chemical filters that absorb UV rays and convert them into heat, or physical filters that block UV rays from reaching the skin.

The Science Behind Bug Spray

Bug sprays, on the other hand, contain active ingredients that repel insects, either by masking our natural scents or by interfering with their sensory systems. [2] Common ingredients include DEET, picaridin, and oil of lemon eucalyptus.

The Key to a Safe and Effective Application

The order in which you apply sunscreen and bug spray depends on the specific products you're using. According to Dr. Melissa Piliang, a dermatologist at the Cleveland Clinic, "It's best to apply sunscreen first, followed by bug spray." [3] This is because sunscreens are typically thicker and require more time to absorb into the skin.

Here's why applying sunscreen first is generally recommended:

• Better absorption: Sunscreen needs to be absorbed into the skin to provide maximum protection. Applying bug spray first could create a barrier that prevents the sunscreen from fully penetrating.
• Reduced effectiveness: Bug spray, especially those containing DEET, can break down sunscreen molecules, potentially reducing its effectiveness.
• Skin irritation: Applying bug spray on top of sunscreen could increase the risk of skin irritation, particularly for sensitive skin.

However, there are some exceptions:

• Certain sunscreen formulations: Some sunscreens, like those containing zinc oxide, can be more effective when applied after bug spray. This is because zinc oxide acts as a physical barrier, potentially preventing DEET from reaching the skin and reducing its effectiveness. [4]
• Spray vs. lotion: If you're using a spray sunscreen, applying it after bug spray might be a more convenient option, especially if you're trying to avoid getting bug spray on your face.

Tips for Successful Application

Regardless of the order, here are some general tips to ensure optimal protection:

• Read the label: Always check the product instructions for specific application guidelines.
• Apply liberally: Both sunscreen and bug spray should be applied generously and evenly to all exposed skin.
• Reapply regularly: Sunscreen should be reapplied every two hours, especially after swimming or sweating. Bug spray should be reapplied according to the product instructions.
• Choose appropriate products: Consider your individual needs and the activities you're engaging in when choosing sunscreen and bug spray.

By following these guidelines and understanding the interplay between these essential summertime products, you can enjoy your outdoor adventures with peace of mind, knowing that you're well-protected from the sun and bugs.
