Do you know the difference between dynamic and static wrinkles?

As you know, wrinkles are modifications of the skin’s surface that are associated with cutaneous aging, sun exposure, and several other factors. They often present as lines, folds, and creases, and they are commonly seen on the face, neck, and hands. The number of wrinkles a person has tends to increase with age.


There is currently no official or definitive classification of wrinkles. Commonly adopted classifications are based on anatomic, dimensional, and etiologic criteria, as well as histological features (e.g., permanent and reducible). You can read more about different types of wrinkles on this article.  


Dynamic vs static wrinkles, what’s the difference?


Dynamic wrinkles (also called kinetic or mimetic wrinkles) are lines that are formed through the repetitive contraction of facial muscles. Over time, these contractions result in the formation of static wrinkles, which are permanent wrinkles that are present even when the face is at rest. Static wrinkles are also caused by gravity and the natural folds in the skin.


The distinction between dynamic and static wrinkles is important in choosing a suitable treatment for aging skin. For instance, the effects of botulinum toxin injection will not be as dramatic on static wrinkles. This treatment is better suited to younger patients who want to prevent the manifestation of static lines. Most patients who receive this treatment are between 30 and 50 years of age.



Factors Responsible for Wrinkle Formation:


  • Lax or loose skin
  • Gravity
  • Decreases in collagen
  • Loss of elastin
  • Repetitive muscle contractions
  • Cigarette smoking
  • Air pollution
  • Sun exposure
