Until recently, UV was considered to be the most damaging radiation to skin, while infrared (IR) was thought to be harmless due to its relatively low energy. However, studies have now shown that infrared not only induces a significant production of free radicals in the dermis, but also diminishes the skin’s antioxidant capacity.
Blue light – also known as high-energy visible light (HEV) – penetrates deeper into the skin than UVA and UVB light. It also has a higher level of energy than IR light, which means there is a greater potential for skin damage to occur.
In studies, blue light has been shown to induce oxidative stress in the skin (which may contribute to skin damage). This includes premature ageing, pigmentation, inflammation and weakening of the skin’s surface.
The need for protection from blue light has arisen in recent years due to the extensive use of digital screens, such as cell phones, tablets, computers and televisions. This is because they all produce a high amount of blue light wave lengths, which is responsible for inhibiting melatonin. Excessive use of these devices – especially before bedtime – can lead to changes in sleep patterns and less quality sleep.
Now, with sunscreen being a mine field of choices, formulation is key; ingredient combinations such as plant stem cells, antioxidants, titanium dioxide and zinc oxide can all effectively protect your skin from harmful UVA and UVB rays. This ultimately reduces sun damage effects and soften the signs of ageing.
At the helm of ingredient innovation is InfraGuard – a cutting-edge 3-in 1-protection against infrared, blue light and pollution. This combination of highly antioxidant tara tree tannins with organic sunflower sprouts is rich in protecting vitamins and minerals, which makes InfraGuard efficient in preventing photoaging. It also protects skin from both environmental and digital pollution – and with regards to antioxidant power – InfraGuard has been found to be almost as powerful as Vitamin C.
Furthermore, InfraGuard protects the skin blocking the formation of reactive oxygen species inside the mitochondria, while supporting mitochondrial functions. This is particularly benefical as UV and infrared are mainly absorbed by the mitochondria, which disturb the production of energy that is essential for the correct functioning of our cells and tissues.

Sunscreen is not an optional extra, but a necessity for all skin types, so look to skin care products that make it as hassle-free as possible.
