Denver Sun: Altitude SPF Lies About Senior Skin?

The Colorado sun, especially in Denver’s high altitude, isn’t just brighter; it’s brutal. Many seniors moving to or living in the Mile High City discover this the hard way, often relying on sunscreens that simply don’t cut it. The marketing hype around SPF numbers can be misleading, and the specific challenges of aging skin at altitude demand a more nuanced approach than what’s typically found on drugstore shelves.

Is Denver Sun’s Altitude SPF really up to the task? Let’s dissect this claim and equip Denver’s seniors with the knowledge to truly protect their skin.

First, let’s address the elephant in the room: SPF numbers. SPF, or Sun Protection Factor, primarily measures protection against UVB rays, the main culprit behind sunburn. It doesn’t fully account for UVA rays, which contribute to aging and skin cancer.

A higher SPF isn’t always better. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. The difference is marginal, and the higher the SPF, the more chemicals are often involved, potentially irritating sensitive skin.

Now, let’s examine Denver Sun’s Altitude SPF. We need to look beyond the marketing and delve into the ingredient list. Are they using broad-spectrum protection, meaning protection against both UVA and UVB rays?

Common UVA filters include:

• Zinc oxide
• Titanium dioxide
• Avobenzone
• Mexoryl SX

If these aren’t present, the sunscreen is already failing. Furthermore, the concentration of these ingredients matters. A low concentration of zinc oxide, for example, won’t provide adequate protection.

Let’s compare Denver Sun to other popular brands available in Denver pharmacies, like Neutrogena, EltaMD, and La Roche-Posay. EltaMD and La Roche-Posay are often recommended by dermatologists for sensitive skin and broad-spectrum protection.

A critical factor often overlooked is application. Most people don’t apply enough sunscreen. The general recommendation is about one ounce (a shot glass full) for the entire body, and a nickel-sized dollop for the face.

Reapplication is equally crucial, especially in Denver’s intense sun. Sunscreen should be reapplied every two hours, or more frequently if swimming or sweating.

Here’s a step-by-step guide for Denver seniors to properly apply sunscreen:

1. Choose the right sunscreen: Opt for a broad-spectrum sunscreen with an SPF of 30 or higher, containing zinc oxide or titanium dioxide. Consider a mineral-based sunscreen for sensitive skin.
2. Apply generously: Use at least one ounce for the body and a nickel-sized dollop for the face. Don’t forget often-missed areas like the ears, neck, and tops of the feet.
3. Apply 15-30 minutes before sun exposure: This allows the sunscreen to bind to the skin.
4. Reapply every two hours: Set a timer to remind yourself.
5. Consider layering: Use a moisturizer with SPF in the morning, followed by a dedicated sunscreen.
6. Don’t rely solely on sunscreen: Wear protective clothing, such as wide-brimmed hats and long sleeves, especially during peak sun hours (10 AM to 4 PM). Seek shade whenever possible.
7. Protect your lips: Use a lip balm with SPF 30 or higher.
8. Check expiration dates: Sunscreen degrades over time.
9. Be mindful of medications: Some medications can increase sun sensitivity. Consult with your doctor or pharmacist.
10. Monitor UV Index: Pay attention to the daily UV index forecast. On high UV index days, take extra precautions.

A common mistake is assuming that sunscreen applied in the morning will last all day. This is simply not true, especially at Denver’s altitude where UV radiation is more intense.

Another pitfall is neglecting areas like the back of the neck and ears. These areas are often exposed and easily burned.

Dehydration can also exacerbate sun damage. Drink plenty of water throughout the day to keep your skin hydrated.

Let’s consider a real-world scenario: A senior living in a retirement community in Aurora, Colorado, enjoys gardening. They apply sunscreen in the morning but forget to reapply throughout the day. They end up with a sunburn on their face and arms.

This scenario highlights the importance of consistent reapplication and comprehensive sun protection strategies.

Another challenge is finding sunscreens that are comfortable to wear. Some sunscreens can feel greasy or heavy, making them less likely to be used consistently. Look for lightweight, non-comedogenic formulas.

For seniors with mobility issues, consider spray sunscreens for easier application to hard-to-reach areas. However, be sure to apply enough to achieve adequate coverage.

Ultimately, protecting aging skin in Denver’s high-altitude environment requires a multi-faceted approach. Don’t solely rely on a single product, especially if its claims seem too good to be true.

Instead, focus on:

• Choosing a broad-spectrum sunscreen with adequate UVA and UVB protection.
• Applying sunscreen generously and reapplying frequently.
• Wearing protective clothing and seeking shade.
• Staying hydrated.
• Consulting with a dermatologist for personalized recommendations.

While Denver Sun’s Altitude SPF might offer some protection, it’s crucial to critically evaluate its ingredients and performance. Supplementing with other sun-safe behaviors is essential for optimal skin health in the Mile High City. Don’t let marketing hype compromise your well-being.
