All digital screens (meaning your laptop, TV, tablet, phone, and screen on which you’re currently reading) emit something called blue light. It can cause damage similar to that of UVA/UVB rays (we’re sure you’re familiar), but because we are exposed to our devices over 12 hours a day on average, blue light may actually be worse for your skin.

While UVA and UVB rays impact the first and second layers of skin, blue light actually penetrates at a deeper level and reaches the third layer, increasing the risk of dullness, discoloration, fine lines, and generally looking as tired as you feel after sitting in front of the computer for hours soaking it in.

But just because artificial blue light is a new threat, that doesn’t mean it can’t be stopped.
