Before your next binge-watching session of your favorite TV show, consider adding an additional task to your preparation routine. Board-certified physician assistant Courtney Moseley, also known as The Plastic PA on Instagram and an Expert ZO Skin Health provider, emphasized the importance of shielding your skin from blue light, which emanates from both our television screens and electronic devices. Moseley explained to He beauty here the skincare measure that many of us overlook—defending against exposure to blue light. “The visible light spectrum encompasses all colors of the rainbow, with blue light constituting about one-third of it. While it primarily emanates from the sun, it is also present in electronic gadgets such as smartphones, laptops, and TVs,” Moseley informed He beauty here. “Due to its short wavelength and deep penetration, blue light is termed high-energy visible light or HEV.”
In contrast, ultraviolet (UV) and infrared rays cannot be seen by the human eye. These forms of light are linked to skin cancers, premature aging, and various other health risks.
Dr. Ahmed El Muntasar explained to “He beauty here” that “any exposure to UV rays results in mutations” that can elevate the likelihood of cancer.
In contrast to unseen lights such as UV, HEV lights pose fewer risks.
Reasons for Early Onset Aging
“Although HEV light doesn’t pose a cancer risk, it’s known to accelerate aging, resulting in wrinkles, fine lines, and pigmentation,” Moseley clarified.
HEV light produces free radicals, causing oxidative stress on the skin, which can degrade collagen and elastin, essential for youthful skin.
Many sunscreens now offer HEV protection, though awareness of blue light’s potential harm in daily life remains low.
“Sunscreens with tint often contain iron oxides, effective in shielding against blue light. Additionally, wearing sun-protective clothing and limiting sun exposure are recommended, similar to UV protection,” Moseley advised. “Integrating antioxidants into skincare can combat free radical damage from blue light.”
Although sun exposure yields more blue light than screens, the latter’s cumulative effect is often overlooked.
“Apply sunscreen with blue light protection to counter HEV exposure from both outdoor and screen sources,” Moseley suggested.
To mitigate blue light exposure further, Moseley recommended using blue light filters on screens, activating ‘night mode’ on phones, and maintaining a distance from screens.
Despite its aging effects, Moseley acknowledged blue light’s benefits, particularly in acne treatment.
“While blue light can contribute to premature aging, it’s also beneficial, notably in combating acne bacteria and reducing sebaceous gland activity,” she concluded.
