A personal Faraday shield for a radiant, high-tech world

However, not only blue light increases the ROS load in keratinocytes leading to skin barrier damage and premature skin ageing. Our modern, highly connected world with permanent access to the internet and communication devices emits a tremendous amount of radiation. A large fraction is WiFi radiation in the range of microwaves. To protect our cell membranes and skin barrier, we need anti-oxidants active in the depth of the membranes to prevent deep lipid peroxidation, followed by functional impairment of these structures. Radicare®-Gold is the skin’s personal Faraday shield made from natural carotenoids to reduce the ROS load provoked from any source.

It has long been known that radiation is the main extrinsic cause of skin ageing as it attacks the skin barrier and increases the oxidative stress inside cells by inducing the formation of ROS. 

The main source of radiation is the sun, which emits radiation of all wavelengths (Fig 1). If all of this radiation were able to get through to the Earth’s surface, it is probable that higher forms of life would not have evolved on our planet. Luckily, the atmosphere absorbs most of the radiation and only a small fraction penetrates to the ground where it can harm our skin. Nonetheless, the residual UV radiation and the high energy fraction of visible light (HEV), in fact blue light, can be harmful to the skin. This is demonstrated by the fact that we become sunburnt if we expose ourselves for too long to the sunlight. The skin pigment melanin and of course the sun protection factors in cosmetic products are meant to protect us against UV radiation but there is no effective sunscreen for blue light on the market, yet.
