You might think sunscreen is only necessary when you’re outdoors, but applying it indoors is also crucial. Here’s why:
1. UVA Rays Penetrate Windows
Sunlight contains two main types of harmful rays: UVA and UVB. While UVB rays cause sunburn and are blocked by glass, UVA rays can penetrate through windows and still impact your skin. These rays contribute to premature aging, fine lines, and wrinkles, and can increase the risk of skin cancer over time.
2. Cumulative Sun Damage
Even brief exposure to sunlight through windows or artificial light can add up over time. Consistent use of sunscreen helps mitigate the cumulative effects of sun damage, protecting your skin from gradual, long-term harm.
3. Skin Protection from Indoor Light
Artificial light sources, such as fluorescent and LED lights, also emit low levels of UV rays. Though the exposure is less intense compared to direct sunlight, it can still contribute to skin damage over time.
4. Maintenance of Healthy, Youthful Skin
Applying sunscreen daily, even indoors, is a simple step that offers significant benefits. It helps prevent premature aging, pigmentation, and other skin issues, maintaining healthy and youthful skin in the long run.
So, whether you’re lounging near a window or working under artificial lights, integrating sunscreen into your daily routine ensures your skin stays protected from all forms of light exposure.
