De-lightful: how to protect your skin from blue light
Just when you thought digital devices couldn’t get any worse, a new menace has emerged, with gathering evidence suggesting blue light emitted from screens damages skin.
High-energy visible light (HEV) generates free radical damage in cells, so add wrinkles, hyperpigmentation, and premature aging to the list of tech-related ailments.
THE DIFFERENCE BETWEEN HEV LIGHT AND UV RAY
“The difference is wavelength,” explains Linda Blahr, National Head of Training and Science for SkinCeuticals, “UV rays are short, while HEV is longer and penetrates deeper, with about 20% reaching the hypodermis.”
“UVB burns the skin and UVA causes ageing by inducing discolouration and breaking down the structural support,” says Linda. In fact, SkinCeuticals’ own research found HEV increased pigmentation in darker skin by 18.1% and 4.3% in lighter tones.
THE SILVER SCREAM
“The best form of defence against UV is a broad-spectrum SPF factor 30+, chemical or mineral,” Linda advises. “For HEV protection, wearing an everyday antioxidant will help protect skin cells from oxidation from the inside.”
The upshot is sunscreen alone isn’t enough. Luckily, there are plenty of serums, mists, creams, and foundations which help purge free radicals. Moisturisers and make-up with built-in defences are the best way to protect skin without having to think about it.
BareMinerals Complexion Rescue Radiant Tint Protective Moisturizer uses cocoa extract to shield skin and gives a fresh, even glow, while Jurlique’s UV Defence Lotion achieves that elusive combination: traceless, light wearing UV protection.
Alternatively, combine your regular sunscreen with a high dose antioxidant, like SkinCeuticals Phloretin CF. For round-the-clock care, add serum. Wear under makeup during the day and apply before bed (after all, who isn’t guilty of a little late-night scrolling?) De Mamiel’s Intense Nurture Antioxidant Elixir has detoxifying malachite and a relaxing herbal scent.
Should your day not require a prepped and primed face for the great outdoors, keep a mist, such Amly’s Digital Detox, within easy reach for a shielding boost.
