ANTI-POLLUTION
Nature inspires a holistic fight against pollution
Marlène De Matos, Julie Despres, Hélène Foliguet – Berkem, France
Pollution is the main aggressive factor of our new age. It is a real social scourge. This new concern can be found everywhere at the surface of the planet; located outdoors, it is also found in our houses. Furthermore, exposed daily, our skin and hair are constantly attacked. Pollutants settle down on our hair, affect them and make them look dull. Scalp skin is irritated and asphyxiated. Extracts from plant leaves have shown
interesting effects acting on various adverse mechanisms of pollution. Those actives are fighting holistically against this major consideration. Breathe, feel, live, treat your skin naturally!
Pollution Nowadays, each of us is exposed to urban outdoor pollution and indoor air pollution. Pollution in general is mainly from human origin and is due to the combustion of fossil fuels or biomass. Urban outdoor pollution is felt by the local population, living in urban districts or in suburbs. It can come from mobile sources, such as car exhaust, static sources like factory releases and energy plants. Indoor pollution is something that no one can see. It can occur from a large variety of products, chemicals or even from our furniture. Pollution is everywhere. According to the WHO, air pollution represents the main environmental risk for human health. It affects all age groups, all socioeconomic groups and all regions of the world. Even if all people, living in the same area, breathe and live in the same air, important geographical differences are noted through the world. Indeed, Africans, Asians and Middle Eastern citizens breathe a much

higher level of pollutants than in other places, and thus expose their skin to it. Air pollution has become one of the main
concerns of the past few years, as human activity is growing (industry, transport, heating). This concern is justified as in 2050 70% of global population will live in urban area, versus 50% currently. In addition, the increasing number of intense air pollution episodes in many cities in the world is alarming.

Pollution is not just a visual or smell
problem, nowadays it has been shown that it is also a risk for our health, our hearts and our lungs. Scientific discoveries have also shown that pollution affects the skin. Indeed, the main role of our skin is to protect our body against external aggression. Various in vivo and in vitro tests are being developed to decipher the influence of pollutants on our epidermis quality and on our cell mechanisms, affecting its balance. Pollution affects the skin’s barrier,

destroying the hydrolipidic film. This will bring a modification of cellular renewal, which will be less fast. Skin looks duller and less shiny. It also has been shown that pollution ages young skin, increasing free radical production which alter cells and by a chain reaction, destroys collagen and elastin fibres.1 Hair is also affected by pollution. Tobacco,
rain, microparticles, exhaust gas and other things affect the hair. Fine particles fix on capillary fibres and cause a lack of shine and radiance. By contrast with skin, hair does not possess a biological defence mechanism. Thus, it is important to protect it. It also can help to fight against sensitive scalp and this maintain shield stability.
