Blue light and sunlight: why protect your skin all year round?

---

When we think about protecting our skin, we often think of summer and the sun. However, between the blue light from screens and UV rays present even in winter, the aggressions are constant. To preserve the radiance and health of the skin, daily protection is essential, regardless of the season. Here's what you need to know to adopt the right habits.

BLUE LIGHT: A DISCREET ENEMY

Blue light is emitted by digital screens (phones, computers, televisions) and LED lighting. Invisible but powerful, it penetrates deep into the skin and can generate free radicals responsible for premature aging. The result: wrinkles, pigment spots, dull complexion, and even inflammation in sensitive skin. What is sometimes called "digital skin syndrome" encompasses all of these skin effects linked to prolonged exposure to screens. To protect yourself, you can use skincare enriched with antioxidants or wear blue light filters on your devices.

SUN RAYS: NOT JUST A SUMMER DANGER

The sun emits UVA and UVB rays, which can cause significant damage to the skin. UVA accelerates skin aging, while UVB increases the risk of burns and skin cancer. What's often overlooked is that these rays penetrate clouds and windows, and reflect off snow, water, sand, and even concrete. Furthermore, altitude increases their intensity. That's why it's essential to apply sunscreen every day, summer and winter, even if you stay indoors.

CHOOSE YOUR SUN PROTECTION CAREFULLY

A simple day cream or makeup containing SPF is not enough for prolonged exposure. It is recommended to use a broad-spectrum sunscreen, preferably mineral, and reapply it every two hours. Mineral sunscreens, such as zinc oxide or titanium dioxide, act like a mirror on the skin's surface. Unlike chemical filters, they do not penetrate the epidermis and cause very few allergic reactions, making them ideal for sensitive skin.

GOOD ACTIONS TO APPLY ON A DAILY BASIS

• Apply sunscreen every morning, even on cloudy days;

• Reapply every two hours during prolonged exposure;

• Complete your routine with antioxidant treatments to counter the effects of blue light;

• Wear sunglasses, hats, and seek shade during hours of strong sunlight;

• Adapt your care according to your lifestyle (outdoors, office, screens, etc.).

Blue light and the sun's rays are two invisible but real sources of damage to the skin. To maintain youthfulness, radiance, and health, a proper protection routine is essential throughout the year. Incorporating good sunscreen and targeted skincare into your routine is more than just a beauty routine: it's a long-term preventative strategy.
