It's no news that spending long hours in front of a screen can have some serious effects on our health, from dry eye and headaches to messed up circadian rhythm and digital eye strain. Turns out, continual blue light exposure can take a toll on our skin as well.
But first off, what is blue light? And how exactly does it impact our skin health?
"Blue light is the shortest wavelength of the visible light spectrum," tells New Orleans-based dermatologist, Dr. Mary Lupo. "It is closest to ultraviolet light which causes accelerated aging of the skin," she adds.
"Sunlight is the main source of blue light and being outdoors during daytime is where we get most of our exposure to it. But there are also many man-made sources of blue light, including fluorescent and LED lighting and flat-screen televisions," notes Visha Skincare founder, Dr. Purvisha Patel. In addition, the display screens of our smartphones, laptops, tablets and other digital devices also emit significant amounts of blue light, adds the skin specialist.
"The amount of HEV light (High-Energy Visible light) these devices emit is only a fraction of that emitted by the sun. But the amount of time people spend using these devices and the proximity of these screens to the user’s face has dermatologists concerned about its long-term effects," says Dr. Patel.
Research shows that blue light exposure can lead to oxidative damage in the skin. "This oxidative stress accelerates collagen breakdown and can cause fine lines, wrinkles and bags," explains Dr. Patel. "The damage is further accelerated by squinting (moving the muscles around the eyes a lot which creates fine lines). In addition, inflammatory hyperpigmentation conditions of the skin such as melasma, can also be exacerbated with blue light," notes the dermatologist.
How do anti-blue light damage skincare products work?
Blue light protection skincare works by physically blocking the light and fighting off free radicals formed by blue light before they can wreak havoc on your skin (photoaging, collagen breakdown, sagging, dark spots, etc.).
For best results, look for products that contain zinc oxide, titanium dioxide, iron oxide and/or antioxidants such as vitamin C as key ingredients, suggests Dr. Kellie Reed, Austin-based board-certified dermatologist.
Even products with green tea polyphenols, Coenzyme Q, resorcinol and vitamin E would work well, says Dr. Katina Miles, board-certified dermatologist and founder of Skin Oasis Dermatology (SOD). Besides, avoid choosing chemical-based sunscreens as they are hormone disrupters and are harmful to coral reefs, suggests the skincare expert.
While anti-blue light damage skincare products are typically safe to use, it's always best to consult with your dermatologist before incorporating anything new into your skincare routine.
Besides wearing an anti-blue light damage cream or serum, "try to dim your screens (without causing eye strain) and use night mode on your devices in the evening to minimize exposure to blue light," suggests Dr. Reed.
Are all kinds of blue light harmful to the skin?
Contrary to what you might think, not all blue light is bad for our skin. "Blue light is one wavelength in the visual light that we see every day. We, as dermatologists, use blue light to treat various skin conditions such as actinic keratosis and acne," explains Dr. Miles.
In addition, it's also used short-term in dermatological practice for treating precancerous lesions—when combined with various topical treatments, adds Dr. Reed.
