The skin cycle is a continuous process where old skin cells are shed and new ones are generated, resulting in the constant renewal of our epidermis. This cycle involves four distinct stages:
- Proliferation: New skin cells are produced in the deepest layer of the epidermis, the stratum basale.
- Migration: These new cells move upwards through the different layers of the epidermis.
- Differentiation: As the cells migrate, they mature and take on different roles, such as producing keratin and protecting the skin from damage.
- Desquamation: The oldest, most mature cells are shed from the surface of the skin.
The length of the skin cycle varies with age and other factors. For example, teenagers experience a skin cycle every 10-21 days, while people in their 40s and 50s experience it every 45-60 days.
The skin cycle is crucial for maintaining healthy skin. It helps to protect us from damage, keep our skin hydrated, and prevent wrinkles.
