When most people think about the health and aging of their skin, the obvious and avoidable aggressors – like spending too much time in the sun, putting pressure on your face while sleeping, using tanning beds, sleeping in your makeup, or smoking cigarettes – usually come to mind. While these all are very important contributing factors to the aging process, they only tell part of the story.
Every day, your skin is damaged by sneaky environmental aggressors, including pollution and blue light from electronic devices. As it turns out, the hours we spend scrolling on Instagram are standing between us and that “#NoFilter I woke up like this” caption.
What is Blue Light?
Blue light is all around us, from the sun’s rays to man-made devices like our laptops, flat-screen TVs, tablets, cell phones, and even fluorescent and LED lighting. The sun emits significantly more blue light than our favorite technology, but the amount of time we spend in close range to electronic devices is taking this exposure (and its associated risks) to new heights.
Why is it harmful?
At 380-500 nm, blue light is one of the shortest and highest-energy wavelengths. Visible Light penetrates skin more deeply than UVA and UVB, and has been shown to generate more ROS (reactive oxygen species) than UVB and UVA combined. This increases the production of free radicals which, as you’ve probably heard, are bad for your skin and your health.
Here’s a fun fact: did you know that four 8-hour workdays in front of a computer is just as damaging to your skin as 20 minutes in the mid-afternoon sun? Putting this in perspective, 7 minutes of sun exposure at 1pm is powerful enough to induce immediate tanning!
Excessive blue light accelerates the oxidation process, stimulates the keratinocytes, and acts on melatonin. Its oxidative effects also elicit inflammation and cause damage to our natural barrier, making your skin less capable of holding onto cellular water and more susceptible to the dangers of environmental aggressors. The result? Skin that shows visible signs of aging, including hyperpigmentation, dullness, and fine lines and wrinkles.
