With regard to the internal factors, the mitochondria and their increasing damage seem to be primarily responsible. The mitochondria are also called the power plants of our cells - and these power plants become weaker over time and produce less energy, which means that our skin can no longer regenerate optimally. The result: we look less fresh and youthful. Furthermore, our collagen and elastin synthesis diminishes over the years, reducing the skin's resilience and causing wrinkles. In addition, as time goes on, the skin is less and less able to produce and retain the moisture it needs. The accompanying lack of moisture leads to the sallow complexion we are familiar with and the dryness lines and wrinkles that often first appear in the sensitive area around the eyes.

External factors that play a role in skin ageing include various harmful environmental influences: UV radiation from the sun and solarium, air pollution and free radicals have a permanent effect on us and our skin and leave traces - our skin appears stressed, we get spots or even wrinkles and sagging, tired skin.
