Technology is what is helping us to discover and connect, but, it is also causing us damage to our skin.
Blue light, also known as HEV (Hight Energy Visible Light) is naturally emitted from the sun, yet it is also produced from our digital devices. Similar to UVA and UVB light, blue light can contribute to premature ageing, and, studies show that adults are spending an amplified amount of time using digital devices. The figures are quite worrying: people now devote over 10 hours-a-day looking at a screen. Moreover, the influential dermatologist Dr Murad explains that, “Spending four eight-hour workdays in front of a computer screen exposes you to the same amount of energy as 20 minutes in the mid-day sun. To put this in perspective, seven minutes of sun exposure at 1pm is powerful enough to induce immediate tanning.”
Unfortunately, Blue light is not only affecting our skin, it’s also having a negative outcome on our sleep. By disrupting our natural circadian rhythm; being exposed to a significant amount of blue light before bed can make it harder to fall asleep. Dermatologist, Dr Stefanie Williams explains blue light “affects the level of melatonin, our sleep hormone.”
Thankfully, there are saviour solutions. As a way to protect yourself from blue light, topical antioxidants are essential in everyone’s skin care regime. Dr Sebagh produced one of the first products that was specifically designed to combat the effects of HEV light, with his Supreme Day Cream. To make it easy, you can also wear a regular SPF to protect your skin from your screens.
As previously introduced, Dr Stefanie Williams also attests: “The skin naturally contains antioxidants such as vitamin E; however, these are used up when the skin is exposed to excess free radicles such as UV light, blue light and other environmental factors such as pollution. Applying topical antioxidants in the form of skincare, as well as eating a diet rich in antioxidants [from fresh fruit and vegetables] can boost our skin’s defence against oxidative environmental damage.”
Evidently, with people spending more time in front of a screen and increasing their exposure to blue light, we need to make sure to take some time away from our devices as well as remembering to integrate SPF products into our skincare routine. Setting a limit such as no screens 1 hour before going to sleep or using an SPF moisturiser are great examples of how we can protect our skin.
