Our skin is exposed to screen light for several hours each day, which contains a high concentration of blue wavelengths. In the visible light spectrum, blue light, also known as "High Energy Visible Light" (HEVL), is a natural component of sunlight that is on the verge of merging with ultraviolet light. Not only does the sun emit blue light/HEVL, but so do the screens of smartphones, tablets, laptops and desktop computers, as well as modern LED and halogen lighting fixtures, among other things.
While the effects of UVA and UVB radiation on our skin are well understood and well researched, the effects of Blue Light on our skin have only recently been investigated in greater depth.
Excessive exposure to blue light, according to the most recent scientific findings, has negative consequences for the skin. Blue Light strikes our skin directly and from a very short distance, causing it to become red. As a result, it has the ability to penetrate unhindered into deeper skin layers, where it can cause the formation of the infamous free radicals.
