Blue light is a high-energy visible light emitted by the sun, but also by digital screens such as televisions, computers, smartphones and tablets. Although blue light benefits our body by regulating our body clock and mood, excessive exposure to this light can have adverse effects on health, including the skin.
Exposure to blue light can lead to increased production of free radicals , molecules that damage skin cells. This damage can cause accelerated skin aging , age spots, loss of elasticity and breakdown of the skin barrier, which can lead to skin that is drier and more prone to inflammation.
Studies have shown that blue light emitted by digital screens can have harmful effects on the skin, as can UV light. A 2010 study published in the Journal of Investigative Dermatology found that exposure to blue light can lead to increased production of melanin , a substance that colors the skin. This melanin production can cause age spots and skin discoloration.
To protect yourself from blue light and prevent harmful effects on the skin, it is recommended to use sunscreens that provide protection against UVA and UVB rays, as well as visible light, including blue light. Skincare products containing antioxidants - such as our Moisturizing Face & Beard Gel Cream - can also help neutralize free radicals and protect skin against blue light damage.
Additionally, it is important to reduce time spent in front of digital screens, especially before bed, as this can disrupt sleep and have harmful effects on the skin. If you work on a computer, you can use screen filters that reduce the blue light output from your screen, or special glasses to protect your eyes and skin.
Blue light can therefore have harmful effects on the skin, including accelerated skin aging, pigment spots and loss of elasticity. To protect yourself, it is recommended to reduce the time spent in front of digital screens, use sunscreens that provide protection against visible light and antioxidants to neutralize free radicals. By taking these preventative measures, we can maintain the health of our skin and reduce the harmful effects of blue light
