“It is scientifically proven that prolonged exposure to blue light, especially that emitted by electronic devices such as mobile phones, tablets, computers, and televisions, can lead to various types of damage. A recent study by researchers at Oregon State University has revealed that this exposure can also have detrimental consequences on human skin.
Scientific studies establish that constant and prolonged exposure to blue light emitted by the aforementioned devices creates problems such as insomnia, eye fatigue, and can also accelerate the aging of your skin, particularly facial skin.
This finding is from researchers at Oregon State University, who conducted a study using fruit to analyze the effects of blue light. They discovered evidence that this light, originating from smartphones and other devices, could affect our basic cellular functions. The results of this study, published in the scientific journal Frontiers in Aging, reveal that blue light emitted by digital LED screens accelerates the aging of fruit flies. The study suggests that blue light alters the levels of metabolites (organic compounds intermediate or resulting from metabolism), chemicals used to maintain proper cellular function in insects. The researchers conclude that this implies that such light could accelerate the aging of human skin.
Dr. Jadwiga Giebultowicz, a professor of integrative biology who led the study, stated that excessive exposure to blue light from daily devices such as TVs, laptops, and phones can have adverse effects on a wide range of cells in our body, from skin and fat cells to sensory neurons. According to these scientists, blue light can penetrate the dermis, the second layer of the skin, where collagen, elastin, and hyaluronic acid are located. Once penetrated, it has the ability to cause dryness, dehydration, pigmentation alterations due to oxidative stress, and prolonged exposure to screens. This can also contribute to increased wrinkles and the appearance of spots on the forehead and around the eyes caused by hyperpigmentation, which is the excessive production of melanin.
Recommendations
To protect skin health and avoid aging cycle alterations, researchers at Oregon State University led by Dr. Jadwiga Giebultowicz, urge people to reduce their screen time to minimize exposure to blue light. Alternatively, adjusting ambient lighting using screen savers and activating night settings on regularly used devices can also be effective.”
