What are the phenomena responsible for premature skin aging?

UVA rays play a very important role in the ageing of our skin cells, but they are not the only cause. Pollution, tobacco, stress and alcohol abuse also have a deleterious effect on the structure of the skin because these factors induce an excessive production of free radicals, known as "oxidative stress". These free radicals degrade certain structures that make the skin "young", such as collagen or elastin fibres.

It is therefore essential to adopt a healthy lifestyle and to protect oneself from UVA rays by using sun products, preferably certified organic.
