Half of the worldwide population lives in cities and is exposed daily to urban pollution. Consequently, pollution has become a public health crisis. By 2030, the urban population will reach 60% and up to 70% by 2050.
The high levels of air pollutants are not limited to China or India anymore as Western capitals like Paris and London often exceed the World Health Organization alert levels. Indeed, it is 90% of those citizens that are exposed to higher levels of air pollutant; particles PM10 & 2,5; than the World Health Organization limits.1 A growing number of scientific and epidemiological studies have demonstrated that human exposure to environmental stress is associated with premature skin ageing and hyper pigmentation.2 The deleterious effect of this stress might be amplified with each other, when combined they form the prooxidant smog also qualified as ‘exposome’.3 The first epidemiological study was conducted on elderly Caucasian women, and showed that exposure to traffic related Particulate Matter (PM2.5-PM10) contributes to skin ageing.2 More studies were performed to provide further evidence that pollution can accelerate skin ageing.4, 5, 6 Not only wrinkle formation but also pigmentation spots appearance could be linked with pollution exposure.2 While the underlying mechanism of action of pollution in skin is not clearly defined, there is strong evidence implicating the generation of Reactive Oxygen Species (ROS) and subsequent state of oxidative stress in all layers of the skin. 5,7,8,9,10,11,12 According to those discoveries, it seems that protecting skin from exposome-induced oxidative stress is the best way to delay skin ageing.
Deep oceans are hostile environments; cold, dark and poorly oxygenated. However, many living organisms evolved to live under these conditions, developing special abilities that have allowed them to survive. Strombine, a rare amino-acid found in many organisms such as sponges, sand worms, oysters, gastropods seemed to play an essential role in cases of environmental stress. In marine invertebrate such as mussels, Mytilus edulis, strombine accumulation was identified as a metabolic stress marker.13 Data suggest that a high concentration of strombine contributes to regulating osmotic pressure in tissues.14 A newly developed strombine derivative compound will act at a cellular level to prevent and repair the harmful effects of stress.
