HOW BLUE LIGHT AFFECTS YOUR SKIN
Yes, I've been researching again and attended amazing online lectures and trade shows right here from home, on my computer, where I'm spending more time than ever! Not only do we need to understand how all this blue light is affecting our sleep, (circadian rhythms) but how it is affecting our skin is crucial too.
While ultraviolet light damages cells’ DNA directly, blue light destroys collagen through oxidative stress. A chemical in the skin called flavin absorbs blue light. The reaction that takes place during that absorption produces unstable oxygen molecules ROS or (free radicals) that damage the skin.
If you’re serious about preventing premature aging, protection from the sun's UVA and UVB rays are no longer enough, as evolving research confirms that blue light – emitted from the sun and our digital devices – is also bad for our skin.
“We are now seeing increasing data on the potential long-term harms of visible light, and in particular blue light, on our skin,” according to many dermatologists such as Dr Stefanie Williams. "It comes as we’re increasingly attached to our digital devices, swiftly being labeled the silent agers of our generation."
With millennials checking their phones an average of 150 times a day according to inc.com John Brandon and with students, such as my daughter, now studying more than ever on their computers I'm sure the numbers from a 2019 report by Rescuetime has these following numbers way up. They found most people, on average, spend three hours and 15 minutes on our phones a day, with the top 20 percent of smartphone users having daily screen time in excess of four and a half hours, that was pre-Covid, now we’re getting significantly more blue light exposure than we used to from just the sun with our devices always at hand.
Studies have shown that even short-term exposure to blue light increases the formation of reactive oxygen species. As we age, the production of ROS naturally increases, however, the body’s ability to repair the DNA damage it causes decreases. Couple this with the increased exposure to blue light from our electronic devices and the skin damage and visible signs of aging rapidly become more evident.
How can we protect our skin from Blue Light damage?
Using blue light protection on your skin such as our City D-Tox Serum and Eye Gel, yes I sent some to my daughter, along with Tizo 2 and 3with zinc and anti-oxidants for outdoors and or alternately for screen time. It is one way to help combat the damaging effects.
Rest and self-care have never been more important. Try turning off your devices at least an hour before bedtime which helps to ready the brain for sleeping. Try reading a book, or do a little self-care on your skin, a bath, yoga, or journal while sipping on a Chamomile tea with a little honey and magnesium.
