HOW DO FACIAL LINES AND WRINKLES FORM?
Facial lines and wrinkles (rhytides) form because of the following factors:
- Aging process
- Sun damage
- Muscle movement
- Other skin diseases with a tendency to scar (eg. discoid lupus)
Fine lines and wrinkles arise because of irregular thickening of the dermis and because of a decrease in the amount of water held by the epidermis. This is mainly caused by sun damage and exposure to environmental toxins particularly tobacco smoke.
Deeper lines or furrows are classified as dynamic or static. Dynamic lines appear with movement i.e. the activity of facial muscles. Static lines are unchanged with muscle movement. Eventually dynamic lines become static.
