Demystifying Spray Sunscreens

As the  summer sun graces us with longer, brighter days, protecting our skin becomes paramount. While traditional lotions and creams have long been the go-to, spray sunscreens have surged in popularity for their convenience and ease of application. But beyond the quick spritz, how effective are they, and are we truly getting the protection we need? Let's dive into the world of spray sunscreens.

Spray sunscreens are, as the name suggests, sunscreens delivered via an aerosol or pump spray. They typically contain the same active ingredients as their lotion counterparts, either mineral (zinc oxide, titanium dioxide) or chemical (oxybenzone, avobenzone, etc.) UV filters, suspended in a liquid base that can be finely misted onto the skin. Their primary appeal lies in their user-friendly design, allowing for quick coverage, especially on hard-to-reach areas like the back, or on squirming children.

This is where the convenience factor meets a crucial caveat. In theory, spray sunscreens are just as effective as lotions, provided they are applied correctly. The challenge, however, often lies in achieving adequate and even coverage. Studies have shown that users frequently apply too little spray sunscreen, or miss spots altogether, leading to inadequate protection. Wind can also significantly reduce the amount of product that actually lands on the skin.  The key to their effectiveness hinges entirely on application. If you can achieve an even, visible layer over all exposed skin, then a spray sunscreen can certainly offer the advertised SPF.

To ensure you're getting the most out of your spray sunscreen, proper application technique is important. Always shake the can vigorously before and during use to ensure the active ingredients are evenly dispersed.  Hold the nozzle about 4-6 inches from your skin. Spraying from too far away results in a significant loss of product to the air.  Do not just mist and go! You need to see a glistening, even sheen on your skin where you've sprayed. Think of it like applying an invisible lotion – you need enough product to rub in.

 This is perhaps the most critical step often skipped. After spraying, immediately rub the sunscreen into your skin with your hands. This ensures even distribution and helps to verify that you haven't missed any spots. Wash your hands thoroughly afterwards. Like all sunscreens, reapply at least every two hours, or more often if swimming, sweating, or toweling off.

Important thing is to never spray the sunscreen directly onto your face.  Instead, spray a generous amount into your hands and then apply it to your face. This prevents inhalation of the product and avoids getting it in your eyes. Also, be mindful of using spray sunscreens around open flames due to their flammability.

There are certain things to look for in a spray sunscreen. Look for broad-spectrum protection as it protects against both UVA (aging) and UVB (burning) rays. Find one that has an SPF of 30 or higher as this  is the minimum recommended SPF for effective sun protection.   If you plan on swimming or sweating, look for "water-resistant" labels (either 40 or 80 minutes).  In addition, be aware of the active ingredients. Mineral sunscreens (zinc oxide, titanium dioxide) are often preferred for sensitive skin. Chemical sunscreens are generally easier to rub in without leaving a white cast. Always look  for a nozzle that provides a consistent, even spray.

Reasons to use a spray sunscreen include the fact that it does provide a quick  and easy application, especially on large areas or wiggly children. It is great for reaching tricky spots like your back.  Finally, there is no need to squeeze out lotion.

There are some issues with using a spray sunscreen.  There is a higher  risk of missing spots or applying too little.  It can be inhaled if sprayed directly on the face, potentially irritating lungs.  Unfortunately, some  aerosols contribute to environmental waste. In addition, these can be more  expensive per application compared to lotions, as a significant amount can be lost to the air.  They are flammable  until dry.

Despite their challenges, spray sunscreens have a place in our sun protection arsenal. Their convenience can encourage more frequent application, especially for those who dislike the feel of lotions or are short on time. For families on the go, or adventurers exploring the vast beauty of Alaska, a quick spray can mean the difference between protected skin and a painful sunburn.

The bottom line: Spray sunscreens can be effective tools for sun protection, but they demand diligent and correct application. Don't just mist and hope – spray, see, rub, and reapply! Your skin will thank you for it in the long summer and beyond.  Let me know what you think, I'd love to hear.  Have a great day.
