Smartphones, tablets, laptops and other screens emit wavelengths causing premature signs of aging.
Blue light damages skin and leaves it prone to signs of premature aging, say the results of recent research. These wavelengths are produced by smartphones, laptops, tablets and other screens we use for hours every day.
Unlike the TV – for most of us – smaller device screens are quite close to our faces.
Smaller screens need to be held closer to our faces so that we can see what they display. As a result, we are exposed to the wavelengths those screens emit, including the blue light that damages skin cells. Though this doesn’t increase the risk of melanoma as is the case with sunlight exposure, photodamage remains problematic, says new research published in the Aging and Mechanisms of Disease journal.
Until now, blue wavelengths emitted from device screens have gained attention for the eye strain they may cause and their potential for harming melatonin production which affects our sleep cycles. That said, research shows that too much exposure to these wavelengths can also promote early signs of aging such as sagging skin, hyper pigmentation, as well as wrinkles and fine lines from broken-down collagen.
Blue light damages skin when exposure levels are too high or two long, such as hours of device use.
In small amounts, these wavelengths can be helpful. However, when taking into consideration the hours spent in front of device screens, it is unlikely that many of us avoid over-exposure.
Since it is unlikely that exposure levels will drop from reduced device use – at least not any time soon – experts are recommending effective anti-aging skin care strategies to prevent premature signs of aging.
Crystal Noble, founder of the British Columbia-based Noble Naturals skin care company, recommends a complete healthful approach to caring for skin in the face of exposure to factors that could lead to signs of premature aging. “When it comes to keeping your skin youthful, there are three important things to remember. Hydration is key, environmental protection is important, and nourishment is essential. To prevent signs of aging, your skin needs to be nourished from the inside out and the outside in. Opt for a natural skincare routine that is rich in plant-based antioxidants, omegas, carotenoids, vitamins, and minerals. When striving for youthful skin, it is also important to stay away from harmful preservatives like paraben,” said Noble.
This aligns with common recommendations made by the American Academy of Dermatology, which recommends a whole-body wellness approach to combatting signs of premature aging such as those that may result when device screen blue light damages skin.
