The Science of Sunlight: How Fall Sun Affects Your Skin

As the days cool down and the leaves start their colorful transformation this season, it’s easy to think the sun’s taken a softer stance too. But don’t be fooled—autumn’s sun is as bright and potent as the summer’s blaze. While we might be swapping our swimsuits for sweaters, it’s crucial to keep sun protection on the checklist. Here, we explore the unique traits of fall sunlight, dispel some common myths, and arm you with essential tips to keep your skin glowing healthily through the entire pumpkin-spiced season.

Effects of Fall Sunlight on the Skin

As autumn arrives, the Earth’s position relative to the sun shifts, changing the sun’s path in our sky. During the fall equinox in late September, day and night are nearly equal in length, and the sun appears lower on the horizon compared to summer’s high, direct angle. This tilt continues as fall progresses, making sunlight travel a longer path through the atmosphere before reaching us. This lengthened path slightly weakens UVB rays, but UVA rays remain largely unaffected.

This shift in season brings not only a change in scenery, but also a subtle-yet-significant impact on our skin health. The persistent presence of UVA rays during fall can contribute to cumulative photoaging, which includes fine lines, wrinkles, and changes in skin texture. Moreover, UVB rays, despite being less intense, continue to pose risks for sunburn and contribute to the development of skin cancer over time.

Fall's cooler air and lower humidity levels can also lead to drier skin, making it more susceptible to Ultraviolet damage. This dryness can compromise the skin's barrier, reducing its ability to protect itself and maintain moisture. Consequently, it's crucial to adapt your skincare routine to include more hydrating products and robust sun protection. Moisturizing with skincare products that contain hyaluronic acid can help lock in moisture and reinforce the skin's barrier.

It’s also important to note that the deceptive coolness of autumn can lead people to spend more time outdoors without adequate sun protection, increasing their exposure to harmful rays. Therefore, integrating sun protection measures into your daily routine remains essential. This includes applying a Broad Spectrum sunscreen with at least SPF 30, wearing hats and UPF-protective clothing, and seeking shade during peak UV hours. 

Sunlight and UV Rays

Despite the seasonal change, the types of ultraviolet (UV) radiation—UVA and UVB rays—continue to impact our skin. UVA rays, known for their role in long-term skin aging and wrinkles, penetrate clouds and even glass easily, meaning they can harm your skin even on cloudy days, or while you're driving or working near a window. And although UVB rays are slightly weaker in the fall, they can still cause sunburns during prolonged exposure, especially around midday.

It's a common misconception that cooler weather reduces the risk of sun damage. However, UV radiation does not diminish as temperatures drop. The sun’s lower angle in autumn does alter the intensity of UV rays, but not their potential to harm. This means that while you might not feel the heat, your skin is still absorbing these age-accelerating rays. And it makes wearing Broad Spectrum sunscreen just as important in the fall as it is in the summer.

Fall Skincare Tips: Nourish and Protect Your Skin

Adjusting your skincare routine is crucial for maintaining healthy, vibrant skin throughout the fall months. Here are a few tips to keep your skin protected and nourished throughout the season:
  1. Sun Protection is Key: Continue using a Broad Spectrum sunscreen with an SPF of 30 or higher. It’s essential for protecting against both UVA and UVB rays, important even on cloudy days. Just remember to reapply every two hours or immediately after sweating or swimming.
  2. Layer Up: Incorporate hats, long-sleeved shirts, and UV-blocking sunglasses into your daily attire. These serve as additional physical barriers against UV exposure, critical in maintaining skin health as the sun sits lower in the sky.
  3. Enhanced Moisturizing: With lower humidity levels, opt for rich moisturizers that lock in hydration and strengthen the skin barrier. Consider serums and creams that cater to cooler, drier conditions, ensuring your skin retains its summer glow even in the fall and winter months. 
  4. Stay Hydrated: Drinking plenty of water is crucial. Cooler weather can lead to a decreased thirst response, yet your skin needs hydration from the inside out to stay plump and avoid dryness.
By integrating these protective and nourishing strategies into your daily regimen, you ensure your skin remains healthy, hydrated, and resilient against the unique challenges of fall weather. Always choose products that align with your specific skin needs and environmental conditions—and don't forget that your skin’s requirements may change as the season progresses.
