Blue light is all around and it’s doing your skin no favours
Counteract the harmful effects of blue light.
High-energy visible blue light (HEV), which makes up the blue light part of the electromagnetic spectrum, is vital – after all, it helps boost our memory, mood and alertness.
The sun provides enough HEV exposure, but in the digital age there’s no escaping an extra dose. Smartphones, laptops, computers, televisions and energy-efficient lighting all emit HEV and may wreak havoc on our skin.
“HEV light can penetrate to the dermis – deeper than both UVA and UVB light – where it can lead to premature ageing, hyper-pigmentation, wrinkles and a loss of elasticity and firming,” says Ocinium founder Cassandra Hilton. “Constantly connected millennials are at increased risk, as are darker skin types who have exhibited a relapse and worsening of pigmentation and melasma when exposed to blue light.”
Your best defence is an antioxidant serum (look for ones with vitamins A, B3, C and/or E) and a sunscreen with a physical shield, such as zinc oxide or titanium dioxide, which help protect skin against HEV’S damaging effects.
Hilton also suggests a blue-light screen filter for your computer, enabling night mode on phones to protect eyes and avoiding digital devices before bed as “exposure to blue light is associated with altered circadian rhythms, which impacts biological skin functions of DNA repair, immunity and rejuvenation”.
