Blue light can cause skin pigmentation, especially in the granular layer of epidermis and deeper skin layer, leading to pigmentation, blackening and long spots. At the same time, blue light, like ultraviolet light, can promote epithelial cells to produce more and more reactive oxygen species, thus accelerating skin aging and leading to skin elasticity and wrinkles.
Other studies show that blue light has a longer wavelength than ultraviolet light, which can penetrate deep into the skin, cause oxidative damage to cellular DNA, reduce the production of collagen and elastin, and lead to skin problems, such as large pores and dark circles. In addition, blue light can inhibit the secretion of melatonin in the brain. If you often use electronic products before going to bed, strong blue light will destroy the balance of hormone secretion, thus affecting the quality of sleep, indirectly leading to dark yellow skin, acne, hair loss and other problems.
In order to resist the harm of blue light, the use time of electronic equipment should be shortened as much as possible to avoid staying for a long time or being in the blue light radiation environment. When using a smartphone or tablet at night, turn on the night mode to reduce the radiation of blue light to the human body. At the same time, in daily life, we can eat foods rich in vitamin A, vitamin E, selenium, beta-carotene, etc. They are all natural antioxidants.
For people who need to use electronic devices such as mobile phones and computers for a long time, it is recommended to take certain protective measures, such as using mineral sunscreen or foundation.
