In a young skin, the balance between regenerating and degenerating processes is greatly in favour of regeneration. The result is soft, elastic, fresh skin. The 28-day cycle (the time it takes for skin cells to naturally regenerate) is visibly working with young skin. With age, the regeneration/degeneration balance is more and more rapidly moving to the side of degeneration. It is not that the skin doesn’t regenerate in your 40s, 50s, 60s… but it doesn’t regenerate quickly and well enough.
How Does Skin Age?
The process happens on all levels:
- Peripheral blood circulation slows down and there is less and less water in the skin
- Exchange of nutrients between cells and the intracellular space is reduced and as a result more cells finish their living cycle faster. This shows as accumulation of hardened, rough skin on the surface.
- The activity of fibroblasts is reduced and since they produce collagen and elastin, there are less new fibres being built in the skin.
- The degeneration of collagen and elastin is increased (they are attacked from both ends – lower rate of regeneration and greater rate of degeneration).
- Face muscles, unlike other muscles in the body, are not attached to the bone but to the skin. This allows human faces to be expressive. In addition, strong facial muscle tone together with collagen and elastin contributes to the young skin’s firmness and tightness. As the muscle tone weakens with age, the skin attached to the muscles also sags. The muscle tone itself is affected by reduced level of neuro-muscular transmitters.
Biological ageing is inevitable and it is a natural process. It can also be slowed down with tremendous success.
