Aspen Sunscreen Lies: Faster Aging at 8,000 Feet
By Franklin Everett ShawThe sun feels different up here, doesn’t it? That warm embrace on your face as you carve down a pristine slope in Vail, Colorado. It feels good, healthy even. But that feeling is a deceptive siren song, luring you towards premature aging and, potentially, skin cancer.
Using a low SPF sunscreen, like an SPF 30, at high altitude is like bringing a butter knife to a gunfight against the sun. It’s woefully inadequate.
Let’s talk about why, specifically in the context of Colorado’s ski towns.
At higher altitudes, the atmosphere is thinner. This means less atmosphere to absorb harmful ultraviolet (UV) radiation from the sun. For every 1,000 feet you ascend, UV radiation increases by approximately 4-5%. Vail sits at 8,150 feet. Breckenridge is even higher, at 9,600 feet. That’s a significant increase in UV exposure compared to sea level.
SPF 30 blocks approximately 97% of UVB rays. Sounds good, right? Not when you factor in the increased intensity at altitude and the reflective properties of snow. Snow reflects up to 80% of UV radiation, essentially doubling your exposure.
Think of it this way: you’re getting blasted from above and below.
That SPF 30 is now struggling to keep up. The 3% of UVB rays that do penetrate are amplified by the altitude and reflection, leading to faster sunburns and increased DNA damage in your skin cells.
This isn’t just about avoiding a painful sunburn. It’s about long-term skin health.
UV radiation is the primary culprit behind premature skin aging, also known as photoaging. It breaks down collagen and elastin, the proteins that keep your skin firm and elastic. The result? Wrinkles, fine lines, age spots, and a leathery texture.
And, of course, there’s the increased risk of skin cancer. Melanoma, basal cell carcinoma, and squamous cell carcinoma are all linked to UV exposure. The higher the exposure, the higher the risk.
So, what’s the solution? Ditch the SPF 30.
You need a high-SPF, broad-spectrum sunscreen. Look for SPF 50 or higher. “Broad-spectrum” means it protects against both UVA and UVB rays. UVB rays are primarily responsible for sunburn, while UVA rays penetrate deeper into the skin and contribute to aging and skin cancer.
Fortunately, you can find excellent options readily available in Colorado. Drugstores and ski shops in Vail and Breckenridge are stocked with sunscreens specifically formulated for high-altitude environments. Look for brands like EltaMD, La Roche-Posay, and Supergoop!. These brands are often recommended by dermatologists and offer excellent protection.
But choosing the right sunscreen is only half the battle. Application is key.
Apply sunscreen liberally 15-30 minutes before heading out. Don’t skimp! Most people don’t use enough sunscreen. You should be using about one ounce (a shot glass full) to cover your entire body.
Pay special attention to often-neglected areas like your ears, neck, and the back of your hands. These areas are particularly vulnerable to sun damage.
And here’s the crucial part: reapply, reapply, reapply!
Reapply sunscreen every two hours, or more frequently if you’re sweating heavily or swimming. Even “water-resistant” sunscreens lose their effectiveness after a certain amount of time in the water.
Set a timer on your phone to remind you to reapply. It’s easy to get caught up in the excitement of skiing or snowboarding and forget about sunscreen.
Consider using a sunscreen stick for easy reapplication on your face. They’re less messy than lotions and can be applied quickly and easily on the slopes.
Don’t forget your lips! Use a lip balm with SPF 30 or higher. Lips are particularly susceptible to sun damage.
And finally, remember that sunscreen is just one part of sun protection. Wear sunglasses to protect your eyes from UV radiation. Wear a wide-brimmed hat to shield your face and neck. And seek shade whenever possible, especially during the peak hours of 10 a.m. to 4 p.m.
A common mistake developers make is thinking that one application in the morning is enough. It’s not. The sun is relentless at high altitude.
Another pitfall is relying solely on sunscreen and neglecting other protective measures like hats and sunglasses. Sunscreen is a crucial tool, but it’s not a magic bullet.
Don’t underestimate the power of the Colorado sun. It’s beautiful, but it’s also dangerous. Protect your skin, and you can enjoy the mountains for years to come. Your future, wrinkle-free self will thank you.
