How Does Blue Light Effect The Skin?
Posted by Laura Rose in Skin Care
We all know by now that too much UVA and UVB exposure is bad for the skin and contributes to premature ageing, but did you realise that blue light - emitted from our digital devices - is also bad for you skin?
This is not the news we wanted to hear when millennials are said to check their phones on average 150 times per day. And it’s not just phones and tablets that give off blue light, computer and laptop screens are also culprits. Which is especially worrying when so many jobs now involve sitting at a computer for 8 hours a day.
So what exactly does blue light do to our skin? Like UVA and UVB it contributes to skin ageing and pigmentation, but studies have shown that blue light can penetrate even deeper into the skin all the way to the dermis where collagen and elastin lives. Blue light exposure at night can also throw the skin’s natural circadian rhythm out of sync, causing skin cells to continue to think it’s daytime, impacting their natural nighttime repairing process.
Sounds like we’re all doomed, right? How do we stop blue light from affecting our skin when we’re so dependent on the devices that emits it?
The Way We Use Our Devices
Unless you want to wear sunscreen indoors 24/7, you need to adjust your device usage. Cutting down the amount of time you spend on your phone or laptop before bed will definitely help your cause, as well as making it easier and quicker to get to sleep. You can also change the settings on your devices to ‘night mode’, changing the screen from blue light to yellow light. Blue light shields are also available to buy to cover computer screens, so slap one of those on your screens at work and jobs a goodun!
As you might expect, one of the best ways to protect your skin against blue light is to wear a sunscreen packing antioxidants. The skin naturally contains antioxidants like Vitamin E, but these are used up when the skin is exposed to excess free radicals. The bareMinerals Complexion Rescue Defense is a broad spectrum, non-chemical mineral SPF 30. Applying topical antioxidants as well as eating a diet that is rich in it (such as fresh vegetables and fruit) will help boost your skin’s defences against environmental damage.
Another great product to have in your skincare routine is Estee Lauder’s Advanced Night Repair Eye Supercharge Complex. It helps to prevent and repair the visible impact of environmental damage (including blue light) all while you sleep.
