We know that applying sunscreen seems silly when it’s cold or windy. If you can’t feel the heat on your skin, it’s easy to believe that you’re unlikely to burn. But sun damage is caused by ultraviolet radiation (UV), not temperature, and a cool or overcast day can have similar UV levels to a warm and sunny day. According to the Skin Cancer Foundation, up to 80% of the sun’s UV radiation still reaches the earth on a cloudy day. Additionally, research shows that wind can actually lead to even worse sun damage in some cases.
Many in the skincare world also recommend that sunscreen be worn inside. Windows only filter UVB rays, but UVA rays still get through. Not only that, but the blue light emitted from our screens and indoor lighting can also damage the skin. In a 2010 study, researchers exposed the skin on the lower back of 20 volunteers to the amount of blue light we get from the sun. What they found was that it caused more pigment, redness, and swelling than when the same person’s skin was exposed to equivalent levels of UVA rays.
For these reasons, SPF is important in almost any situation. And for even further protection, COOLA’s BlueScreen(TM) Digital De-Stress(TM) technology–used in their Sun Silk Drops, Refreshing Water Cream, and Dew Good Illuminating Serum–helps to mitigate the effects of High Energy Visible Light (including blue light from digital devices), as well as infrared light and pollution.
