The latest research had found that the protection from UVA and UVB rays is no longer enough, as up to date investigations confirms that blue light (produced from the sun and our digital devices) is also bad for our skin.
These studies have found that blue light induces oxidative stress in the skin, and for this reason, this can contribute to skin aging, as when we exposed to UVA. Besides, blue light penetrates deeper into our skin compared with UVA and UVB lights. In fact, blue light penetrates profoundly to our dermis, where collagen and elastin are located.
Moreover, environmental stressors can also damage our unprotected skin and reduce the availability of elastin, leading to loss of elasticity, skin photoaging increasing wrinkles appearances, fine lines, and hyperpigmentation.
However, the cosmetics industry had been working in many advances for products against the blue light damages in our skin.
Lately, it’s been found a way for blocking the screen blue lights by using superficial CO2, extracted from a subtropical fruit known as Chinese lantern.
In vitro testing showed that this new screen light block acts differently under varied stress conditions. Under visible light and under conditions of artificial pollution, the bioactive decreases melanin synthesis in the skin. Under UV stress, it protects collagen and increases skin elasticity. Also, it helps to reduce the appearance of dark spots and helps reduce the presence of fine lines and wrinkles.
