SKIN PROTECTION 63
A personal Faraday shield for a radiant, high-tech world

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.
Digital skin ageing in the modern world
HEV light is not only produced by the sun. Recent studies have shown that exposure to the sort of displays present in TVs and smart devices that also emit blue light can result in severe insomnia as the production of the sleep hormone melatonin is suppressed.1 Furthermore, it has been clearly demonstrated that blue light is able to induce ROS formation in epithelial tissue,2 as such it may advance premature skin ageing.
In addition to light in the visible and
infrared spectrum, the sun also emits microwaves and radio waves. However, their energy is too low to have any damaging effect on our body as they are mostly blocked by the atmosphere. As a consequence, our skin has not naturally developed ways of dealing with this potential threat. The effects of the artificial overload of these forms of energy created by us humans on Earth - so-called

Figure 1: We are surrounded by all kinds of radiation from natural and human-engineered sources. Some rays are definitely deleterious to our skin although for most radiation no clear evidence of their harmful potential exists. Visible light is only a minor fraction of the radiation that hits the skin’s surface.
‘electrosmog’ - are currently being investigated. There is no doubt that the radiation levels of our everyday devices - mobiles, computers, televisions etc. - are low. Nonetheless, the massive increase in the number of smart devices in use, the
extension of the mobile network and the use of mobile phones close to our bodies mean that continuous and potentially harmful irradiation of body tissue can occur. Although there is as yet no definitive proof, evidence is beginning to emerge that the
PERSONAL CARE EUROPE Abstract
Radiation outside the UV-range is one of the most unexplored threats for our skin. For sure, we protect ourselves against UV light but forget the high-energy visible light fraction. 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.
