What is blue light?
Blue light is a range of the visible light spectrum, defined as having a wavelength between 400−525 nanometers. It accounts for 50% of the sunlight spectrum and is the only part of light that is visible to the naked eye. Most of our blue light exposure comes from the sun, but it also emanates from your smartphone, computers and TV screens. We’re all aware of the damaging effects of UV rays and the importance of wearing sunscreen to protect our skin but exposure to blue light can also be harmful – especially given our close proximity to smartphones and laptops.
How blue light affects skin
Blue light promotes stressors in skin that can cause photo-ageing; that is, ageing from exposure to light. Long-term blue light exposure can cause skin damage, including discolouration, inflammation, and weakening of the skin’s surface.
How to protect your skin from harmful blue light
As with most things health-related in life, protecting your skin from harmful blue light starts from within, with a diet rich in antioxidants (blueberries, strawberries, kale and artichokes are all good sources) and fatty acids to reduce and protect against inflammation. Topically, you can also add skin care products into your ritual that contain antioxidants, to prevent harmful free radicals and inflammation generated by light pollution. Our Rosewater Balancing Mist is not only hydrating for the skin, but it contains our exclusive Jurlique Rose extract which is a powerful antioxidant.
Our iconic Herbal Recovery range is packed full of antioxidants, containing extracts of Viola Tricolor, Nasturtium, and Yarrow, that help to hydrate your skin naturally, leaving you with skin that is soft, smooth, and revitalised.
