Understanding Wrinkles
Wrinkles are similar to fine lines however, can be a little more complex as they appear deeper and more prominent in the skin. Fine lines are often superficial whereas wrinkles are deeper set in the epidermal layer.
What causes wrinkles
These deeper lines are predominantly caused by muscle contractions underneath the skin, which is often why they appear where you make the most facial expressions. They can also be enhanced by external factors and exposure to the natural environment like UV rays from the sun.
Some of the most common facial expressions where wrinkles occur include:
- Dynamic wrinkles
One that only occurs with movement. For example, if you frown and see a deep crease between your eyebrows which disappears when you stop frowning, that is a dynamic wrinkle. - Static wrinkles
If you are relaxed or resting and your wrinkle or crease stays visible that is a static wrinkle.
