Factors harmful to our skin according to Dr. Christophe Desouches Plastic surgeon in Marseille
You probably know the definition of the genome but have you ever heard of the exposome? It corresponds to all the responsible environmental factors at 80 % signs of age.
On the one hand, we have the genetic heritage. On the other, the usual environmental factors: UV, pollution, tobacco, but also food, stress, sleep. This tells us that 80 % signs of aging are not genetic but linked to these external influences. The exposome therefore takes into account all the internal and external exposures to which the skin is subjected.
We already know that the skin is impacted by different intrinsic and extrinsic factors. What new elements does this notion of exposome bring?
Until now, factors such as UVA, UVB, tobacco, infrared, food, stress were studied separately. Today, scientists are trying to understand the interactions between them, the cumulative damage to the skin.
The approach is more global. We know, moreover, that each individual has his own exposome, which varies according to the way of life, the place where we live, the season? But everyone also has their own genetic heritage which allows them to fight more or less effectively against the deleterious factors of the exposome!
