How do digital screens affect skin?
In simple terms, a digital screen; be it on a phone or computer emits blue light. So besides causing ‘tech-neck’ and spreading bacteria, blue light is yet another concern caused by digital devices.
What is blue light?
Across the light spectrum, blue light has a short wavelength that is high in energy. It falls in the middle of the spectrum between UV rays and infrared rays. While blue light is present in natural light, it is also emitted from digital devices. Blue light gives out a glare and flickers, which affects the sharpness and clarity of a viewer’s eyesight, besides the rest of their health in numerous ways.
How does blue light damage the skin?
As much as we may love our gadgets, blue light from them can cause the skin a great deal of harm.
If you use your gadget at night, their blue light can suppress the supply of melatonin, which shifts the circadian rhythm of the body. This throws off the body’s natural sleep cycle and causes sleep deprivation. Unfortunately, sleep deprivation can have a direct impact on the skin. Not only does it dehydrate the skin, it also leads to puffy eyes and dark circles. Blue light also reaches deeper than most other rays right into the hypodermis of the skin. This hinders the production of collagen and elastin in the skin, which leads to wrinkles and sagging.
