As with any other radiation, excessive exposure to blue light accelerates skin aging. With the increasing presence of devices such as mobile phones, computers or tablets in everyday life, it is important to know how to protect the skin.
Everyone knows about the effects of UVA and UVB rays. But UV rays aren't the only ones to watch out for. In today's electronic world, a lot of power is given to blue light (HEV). Moreover, we get it not only from electrical appliances, but also from the sun.
As with any other radiation, excessive exposure to blue light accelerates skin aging. One of the skin damages is oxidation , and as a result of this oxidative stress, free radicals with a destructive effect are produced - collagen and the extracellular matrix are degraded, as a result of which wrinkles deepen and the oval of the face recedes.
Blue light also causes skin dehydration , as it causes a decrease in the amount of aquaporin, a molecule responsible for maintaining the skin's moisture level. In addition, blue light activates metalloproteinases, which accelerate the breakdown of collagen, causing wrinkles and loss of elasticity.
Finally, exposure to blue light can lead to the formation of pigmentation spots thanks to a molecule called opsin 3.
Some products act as a technological shield, protecting us from these damages, as they contain active substances that carry out antioxidant activity. aox ferulic acts as a biological protector against oxidation caused by blue light. In addition, it improves collagen synthesis and protects the cells responsible for its production, improving skin elasticity and turgor.
It is also important to use sunscreens that protect not only from UVB and UVA rays, but also from visible light and mainly from blue light.
