How is blue light affecting your skin?
While UV light has been one of the major culprits causing skin ageing, wrinkles and pigmentation, HEVL (High Energy Visible Light) or the blue light emitted by electronic devices is one of the more recent health-damaging factors that modern lifestyles expose us to. Although you might not see any immediate redness like after sun exposure, blue light might be guillty of inducing silent damage on our complexions. There are plenty of studies that prove the damaging effects of blue light on our bodies, beginning with their interference with the circadian rhythm and natural sleep patterns, leading to sleep deprivation, insomnia and chronic fatigue, and becoming possible causes of increased risk for depression, as well as diabetes and cardiovascular problems.
When it comes to skin damage, blue light might not be as harmful as UV rays, which lead to DNA mutations and long-term deterioration of skin tone and structure. However, the effects of HEVL-induced sleep deprivation are very clear, with the overproduction of stress hormone cortisol interfering with skin’s self-regeneration cycle and contributing to breaking down collagen and elastic tissue, while also promoting inflammation and older-looking skin. And there is another proven consequence of lack of sleep and exposure to blue light, namely the decrease of skin’s antioxidant levels, making it more prone to external attacks and hyperpigmentation.
The good news is that you can prevent all these from happening.
