Light from electronic devices age almost as the sun rays.
Daily overexposure to LED light from mobile devices, whether computers or smartphones, can cause negative effects on skin health. Maybe you've heard more about the dangers of blue light lately because we're more likely to be at home and online. Our laptops, cell phones, tablets, televisions, and even LED light bulbs are sources of blue light. And now that we are glued to our devices, are we soaking up that light? Should we be more concerned about the damage our skin suffers?
Although at first, it goes unnoticed, the light of the mobile causes a damaging impact on the skin that can affect premature aging.
Although ultraviolet light directly damages the DNA of cells, blue light destroys collagen through oxidative stress. A chemical in the skin called flavin absorbs blue light. The reaction that takes place during absorption produces unstable oxygen molecules (free radicals) that damage the skin.
What damage can the light emitted by electronic devices cause to the skin?
- Oxidative stress
The skin activates melanocytes to increase the production of skin melanin as a defense against frequent exposure to light.
Likewise, it affects the water status of the skin and the skin barrier because exposure to this radiation alters the synthesis of some proteins and interferes with the production of collagen and elastin, thus accelerating skin aging.
The effects these lights cause on the skin also affect the eyes, the circadian rhythm and the sleep cycle.
What do I do to avoid it?
Since the effects of this light have been discovered, a lot of cosmetic brands are working to bring out the necessary products to protect our skin. But, so far, what you can do is, first of all, reduce the time you expose yourself to these devices (be it your mobile, computer, or tablet), apply sunscreen every day, even if you don't leave the house, and include more vitamin C in your diet, which will help reduce premature skin aging.
