It's a proven fact: dermatologists agree that 80% of skin ageing is due to the environment! In reality, age and genetics only account for the remaining 20%. So, unless you live on a desert island, it's hard to avoid ozone and fine particles... Fortunately, more and more anti-pollution cosmetics are emerging, specifically dedicated to this new beauty issue. 

If the skin is our protective barrier against external aggressions, its shielding role can quickly be undermined by pollution: ozone oxidizes the skin's lipids and thus weakens its shield, while fine particles infiltrate our cells. In fact, fine particles make certain receptors hypersensitive, even though they are necessary for cell renewal and to enable the skin to regulate melanogenesis, thus avoiding any pigment spots. All these repeated daily attacks exhaust our defense system, forcing us to be constantly on the alert. 

As a result, the skin becomes deficient in vitamins E and C (its main antioxidants), leading topremature skin aging and a much duller complexion. An oxidative cascade follows: our collagen degrades and deepens wrinkles, pores dilate... and sebum production goes into overdrive, increasing the risk of blemishes. the risk of imperfections ! In fact, it's common to see surface shine but deep-seated dehydration in urban skins, which complain of tightness. Last but not least, some will also suffer from skin sensitivities - redness, patches - as their hydrolipidic film is weakened.
