How do wrinkles appear? Why does collagen disappear over time?

Wrinkles are visible on the outer surface of the skin, the epidermis.

The birth of wrinkles takes place one level below, in the dermis.

Collagen, elastin, hyaluronic acid and fibroblasts are found in the dermis. These are the essential constituents of the skin. Their presence ensures the maintenance, firmness, suppleness and hydration of the skin.

As these elements age and become damaged, wrinkles and other signs of ageing appear.

With age and external aggressions, the body's natural collagen level decreases.

This is why it is necessary to make up for the lack of collagen that appears with time by restarting the production of this protein.

Collagen fibres undergo the natural effects of the passing of time by becoming brittle, thinner and less resistant. Like all other cells in the body, they undergo a natural ageing process.

In addition, the fibroblasts that create collagen are cells that also justify and are therefore less able to produce new collagen fibres.

In addition, external factors increase the appearance of wrinkles and aggravate the ageing of collagen fibres.

Indeed, the sun and UV rays, pollution, tobacco, alcohol, fatigue, light from screens, poor diet, lack of sleep... are sources of oxidative stress that attack collagen fibres and make them fragile.
