BEWARE BLUE LIGHT DAMAGE —

we know we need to keep our skin protected from sunlight — but what about blue light? studies have shown that the light emitted by our tech devices can wreak havoc on our skin, including speeding up signs of aging. the way to avoid this is to put our phones down and spend less time staring at screens (of course, easier said than done). another way is to use products that defend against blue light damage — but what would those be exactly?

there are both potential benefits and negative impacts on the skin. the power of blue light is captured by skin care devices to treat acne and other skin conditions, including pre-cancerous growths when used in combination with certain medications however when exposed to blue light via artificial sources, such as your phone screen, studies found that it can lead to hyperpigmentation in those with darker skin. blue light can also contribute to fine lines and wrinkles. studies suggest that exposure to blue light might stimulate the production of free radicals in the skin, which can accelerate the appearance of aging. free radicals are unstable oxygen molecules that can damage cellular structures like DNA, lipids, and proteins. when those structures are damaged, it can contribute to the formation of aging skin, such as wrinkles.

so let’s talk prevention. there are a few expert-approved ways to defend against blue light damage that don’t involve a digital detox:

•Use a physical sunscreen: the best defense against blue light damage is to use sunscreen with iron oxide — particularly tinted sunscreens.

•Dim your tech devices: dimming your computer or cell phone screen is another way to reduce the intensity of blue-light exposure.

•Try a blue light screen protector: you may have seen blue light glasses being marketed to defend your eyes from blue light, but there are also blue light screen protectors for devices that offer even more protection.
