Bioderma - Woman exposed to sun

We now know that the skin is subject to two types of ageing:

  1. Intrinsic ageing
    This is chronological ageing, a consequence of the passing of time that affects the entire body and depends on genetic, physiological and sometimes even pathological factors.
  2. Extrinsic ageing
    This ageing is linked to lifestyle, primarily sun exposure, but also smoking, stress and even pollution.

Key points

  • Loss of radiance
  • Wrinkles and fine lines
  • Loss of firmness
  • Dryness
  • Discomfort
  • Pigmentation marks

Along with these two processes, we have to deal with oxidative stress, a major cause of skin ageing. This biological phenomenon is generated by free radicals that damage the structure of cells like those in our DNA, membranes, proteins, etc. Our body naturally produces free radicals and our cells normally have a defence mechanism. With age, an imbalance grows between the external stressors (oxidation) and the body’s defence capabilities (antioxidants).

The number of potential stressors increases with age and life experiences (UV radiation, pollution, smoking, etc.), the body’s defences are overwhelmed and ageing accelerates… This is why antioxidants play a crucial role in fighting ageing. They are molecules that inhibit free radicals, either by trapping them (vitamins C and E) or by strengthening the skin’s anti-free radical systems (selenium, zinc, coenzyme Q 10 and superoxide-dismutase). They limit the harmful impact of oxidative stress on the skin’s cells, which is responsible for cutaneous ageing.

Are we all equal when it comes to ageing?

No, we are not all equal when it comes to ageing! Some people have skin that becomes "marked" more and more quickly than others. For example, fine, dry skin becomes wrinkled more easily than thick, oily skin. People with white skin develop more wrinkles than people with black skin. Genetics and our lifestyles influence the skin’s ability to regenerate itself.
In all cases, you should already be protecting young skin from environmental factors likely to weaken it (sun, pollution, free radicals, etc.). Then, you can use an anti-ageing treatment at any age to maintain your skin’s suppleness, radiance and tone.

The skin is a tissue that fully renews itself every 28 days in normal conditions. These products work to restart the biological mechanisms that slowly lose momentum as we age: the epidermis renews more slowly, skin becomes thinner, exchanges between the dermis and the epidermis decline, skin components break down, etc.

Mature skin has a harder time rebuilding itself. It needs specific treatments that will create optimal conditions to help it regenerate. This tissue regeneration process is essential for fighting skin ageing because the skin is a highly sophisticated barrier that protects us from our environment.

It is easy to understand that the better it is cared for, the stronger it will be to combat various stresses and the less marked it will be. The skin is like a wall: it should be both supple and resistant. Proper tissue regeneration maintains it and keeps it in its optimal state.
