Do You Need to Wear Sunscreen Indoors? The short answer? Yes!
You probably know that applying SPF on the regular is a must when you decide to spend time outdoors, whether you’re headed to the beach or a rooftop. One of the most common misconceptions is that you don't need to wear it indoors. Unfortunately, that's not true — not even a little bit. Sunscreen isn’t just a must for when you leave your house. Sun exposure can cause skin damage, including premature aging like wrinkles and dark spots, and it can happen even in the comfort of your own home.
Here’s why: The Skin Cancer Foundation states that most windows block UVB rays, the type that typically give you a sunburn. They don’t block UVA rays. You’ll think you’re just getting a beautiful tan or you’re not getting the sun’s rays, but UVA rays can go deeper into our skin than UVB rays and really degrade our collagen production.
Whether you’re in the car or in your home, it’s important to take proper sun protection measures, including wearing sunscreen. Alternatively, the Skin Cancer Foundation states that another indoor sun protection option is to have a UV-protective film applied to your windows.
Joshua Zeichner, M.D., director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City, says, “Lightbulbs, especially LED bulbs, as well as the screen from your computer or device emit high-energy visible (HEV) light,” he says. “This is light in the blue spectrum that has been shown to penetrate into your skin and contribute to the development of both wrinkles and dark spots.” Basically, some studies say exposure to screens can cause wrinkles.
The solution is to apply a sunscreen that blocks UVA rays as well as UVB rays. There’s also some evidence that you can protect yourself from HVA rays by using product contains antioxidant-rich ingredients, such as La Coess Organic Face Oil.
It might be tempting to skip sunscreen while staying inside, but it's in your skin's best interest to slather it on while you at-home.
