What is oxidative stress?

Oxidative stress, impossible to miss. And for good reason: it is the first source of skin aging. But what exactly is oxidative stress? How does it work ?And, above all, how to prevent it effectively? 

Oxidative stress: definition

Oxidative stress (or oxidative stress) is a completely natural phenomenon , from which no one escapes. It is neither more nor less than a chemical reaction, in which oxygen is involved . He is the big responsible!

Once captured by the body (when you simply breathe), the latter triggers the production of molecules called ” free radicals “. They are essential to life: they are the ones that help you, among other things, to defend yourself against viruses.



Normally, the amount of free radicals present in your body is carefully controlled by your cells, which are responsible for eliminating them. The problem is when your body can no longer keep up and free radicals build up to excess. This imbalance causes chain reactions that gradually destroy your healthy cells : this is called “oxidative stress”.

Factors behind oxidative stress

This dysfunction in the regulation of free radicals generally occurs as a result of aggression inflicted on the body. For example, if you have suffered from a serious illness or followed a heavy drug treatment, it is entirely possible that your body has emerged from it weakened, and that it is now struggling to protect itself adequately against these invaders.

But the most common causes remain linked to a contemporary lifestyle : pollution, physiological stress, sedentary lifestyle (and even the abuse of sports activities) or too regular sunbathing sessions are all factors that may upset your organism and lead to oxidative stress. Without forgetting, of course, smoking.


The Consequences of Oxidative stress on the skin


Obviously, this imbalance is not without consequences. Oxidative stress causes a lot of damage. The damage sets in little by little, as free radicals gain ground in your body. They attack the constituents of your cells, until they oxidize them completely. In short, it’s as if your cells are rusting! Result: your tissues and organs age prematurely .


And the skin is not spared from this aging process. Attacked by oxidative stress, it gradually relaxes , loses tone and firmness . The lines and wrinkles prematurely mark the face. In short, the functioning of the skin is seized up. If this process remains inexorable, it is fortunately possible to delay its onset. How? ‘Or’ What ? By focusing on good gestures and targeted care!
