Blue light and its effects have become a global topic of mounting debate. Blue light is a short wavelength, high-energy light which is part of the visible spectrum. It is also known as High Energy Visible Light (HEVL). Blue light can have damaging effects on the skin.
We all are surrounded by blue light. Sun is the main natural source of all blue light. Other sources are artificial, but they can contribute to significant doses. These include smartphones, screens, computers, TV and indoor lighting. Most of us are regular users of these devices making it likely that each of us is exposed to the effects of blue light.
However, blue light is not all bad as blue light from the sun has some health benefits.
It naturally regulates your body’s circadian rhythm which is your natural sleep-wake cycle. Moreover, healthy exposure to blue light can elevate your mood and helps to improve your memory and cognitive function.
The blue light wave-length is also used in LED devices to reduce acne inflammation.
The damaging effects of HEVL on the skin though have been documented.
Blue light is known to produce oxidative stressors, leading to the formation of free radicals, known as “Reactive Oxygen Species (ROS)”.
These free radicals force your skin to produce enzymes that break down of collagen and elastin. Collagen and elastin are vital components of your skin providing youthful support. If your skin receives excessive blue light, these can happen:
Although aging is a natural process, blue light exposure speeds up this process. What’s worse, blue light also increases melanin production, leading to uneven skin tone and worsening of melasma. Plus it disrupts your beauty sleep, interfering with levels of melatonin in your body.
To avoid unnecessary blue light, limit the time spent with digital devices, especially at night, and invest in device blue light filters. Some devices come with a display blue light filter that you can switch on for additional protection.
Next, use your anti-HEVL high potency Melanopeel® antioxidants and sunscreens.
