We are all very aware of UV exposure can impact the skin, creating damage that can range from premature wrinkles to dangerous skin cancer. Damage from UV exposure is cumulative and increases your skin cancer risk over time.
But did you know that Blue light also can affect the skin and can have damaging effects to our eyes.
In the next few years its estimated that 90% of all indoor light will be from sources of high-energy blue light.
Blue light waves are the among the shortest, highest energy wavelengths in the visible light spectrum. Prolonged exposure to Blue light exposure may increase the risk of macular degeneration. The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina.
We are only finding out now the impact it is having on our skin. It has been shown that long-term blue light exposure to concentrated sources of blue light energy can cause skin damage, including colour changes, inflammation, and weakening of the skin’s surface. Simply put, blue light promotes stressors in skin that cause photo-aging; that is, aging from exposure to light.
There is evidence that blue light “contributes to brown spots on the skin and hyperpigmentation such as melasma, and possibly to photoaging and the breakdown of collagen, which leads to wrinkles and skin laxity
There was a study done in 2015, suggesting that exposure to blue light might stimulate the production of free radicals in skin, which can accelerate the appearance of aging.

Dermatologists have good evidence to show that visible light triggers certain skin conditions, such as melasma, where the skin is stimulated to produce more pigment.There’s also evidence that as blue light penetrates the skin, reactive oxygen species are generated, which leads to DNA damage, thereby causing inflammation and the breakdown of healthy collagen and elastin, as well as hyperpigmentation.”

THE GOOD NEWS
There is some exciting and promising research that supports that Lutein and Zeaxanthin two powerful anti-oxidants can filter blue light and protect the skin and eyes from environmental factors including high energy sources like blue light.
These antioxidants may be able to block the formation of melanin pathways, decrease inflammation and increase intracellular antioxidants.
“Lutein and Zeaxanthin work like an internal sunscreen for your skin, and sunglasses for your eyes”
