Beyond UVA and UVB
For years, we have been warned about ultraviolet rays (UVA and UVB) and for good reason: they penetrate the upper layer of the skin to reach the lower layers where they damage or destroy cells.
But did you know that the sun also emits “blue light” of the same type that is emitted by the various screens of electronic devices or by LED bulbs? In the case of the sun, the emissions are 1,000 times more intense. You would have to sit for 64 full consecutive days in front of your computer screen or tablet to absorb as much blue light as you would from one hour of exposure to the sun.
Blue light changes the natural functioning of the dermis, slows down the production of collagen and elastin, and promotes cell oxidation, which means the skin will have more difficulty regenerating itself later. Basically, blue light makes us age faster.
Sunscreens protect against blue light. Some experts recommend applying sun protection when our screen exposure exceeds two hours.
Instead, at Figurra, we reiterate to apply sunscreen every day, even if you don't spend much time in front of a screen or don't see the sun. The rays sneak in just about everywhere.
