Wrinkles form through two main mechanisms. Dynamic wrinkles are caused by repeated facial muscle movement over years, such as squinting, smiling or frowning. Over time these movements etch lines into the skin that eventually remain visible even at rest. Static wrinkles, on the other hand, are present at rest and are driven by a loss of collagen, elastin and volume in the skin and underlying tissue.

Sun damage, smoking, dehydration and genetics all accelerate the formation of both types. Most people develop a combination of dynamic and static wrinkles over time, which is why a single treatment approach does not always address the full picture.

Understanding the type and cause of your wrinkles is the starting point for effective treatment. Dynamic and static wrinkles respond to different approaches, and the right plan depends on a proper assessment of both.
