So-called young skin is skin whose cell renewal is very rapid, therefore every 21 days. However, over the years, this renewal slows down due to several factors:
- the individual biological clock;
- the stress;
- the lifestyle;
- skin maintenance;
-
the environment.
This is when the process of premature aging begins. We see the appearance of expression lines and often superficial dehydration. From the age of 25, the skin loses 5% of its collagen each year. The first wrinkles will appear slowly over the years.
