Ultraviolet Radiation and Photoaging Damage
The harmful effects on the skin caused by ultraviolet radiation, these days are now well known to everyone, so much so that the names of the different wavelengths are derived from the English term related to the type of damage they can cause, specifically UV-B 280-315 nm (B for Burning/ scalding), UV-A 315-400 nm (A for Aging/aging).
The harmful effects of these radiations are due to their ability to penetrate the skin and induce the production of reactive oxygen species (ROS) better known as “free radicals”. Our body has a natural antioxidant defense process that neutralizes the harmful effects of free radicals. However, when external causes, such as exposure to ultraviolet radiation without adequate protection, intervene, it creates an excess of free radicals that the body cannot neutralize, inducing the production of oxidative stress.
Among the negative effects produced by oxidative stress is also skin aging with the appearance of wrinkles, dark spots and dyschromia. This is why the use of sunscreens has become a standard protocol to prevent photoaging damage to the skin.
The Harmful Effects of Blue Light on the Skin
It is known that the longer the wavelength the deeper the radiation is able to penetrate the skin. Longer wavelengths are, therefore, associated with a greater potential for free radical generation. Recent research has been paying particular attention to the effects of high-energy visible light (HEV), otherwise known as Blue Light, which, because of its longer wavelength, can reach deeper layers of the skin than ultraviolet radiation. These are radiations, from 380 nm to 495 nm, generally emitted by electronic devices such as smartphones, tablets, TV and computer screens.
Blue light is able to penetrate much deeper into the skin, passing through the dermis and reaching the hypodermis. Here it is able to induce a high level of intracellular oxidative stress, with toxic effects that reduce the production of keratinocytes and fibroblasts resulting in a reduction in the quantity and quality of very important molecules such as collagen, elastin and hyaluronic acid that are essential for the skin. The obvious effects of such a process are, therefore, the onset of wrinkles, volumes that sag under gravity, dull complexion, dehydration, inelastic and thin skin.
Bio-Complex Radiance Licofarma
Protecting the skin from the harmful effects of radiation, particularly those emitted by blue light, has become a real challenge for cosmetics, considering the large number of devices we use every day for work and leisure.
Il Licofarma's Bio-Complex Radiance goes in this direction. It is a complex that, by exploiting the luminescent properties of the plant extracts of which it is composed, is able to transform high-energy radiation into low-energy emissions. Specific tests show its effectiveness in reducing the amount of incoming energy resulting in protection of dermal and hypodermal structures from radiation. Licofarma's Radiance Bio-Complex is not only an exceptional active ingredient that can give skin a radiant, glowing appearance, but also protects against the damaging effects triggered by UV and HEV light (blue light), and was used in the formulation of our Rebel Ialufiller Ageless 40+.
It is an innovative hydrating, brightening and anti-wrinkle serum with an immediate lifting effect that acts on the main signs of aging, indicated for particularly wrinkled skin lacking in tone, dehydrated, with a dull and dull complexion.
