Wrinkles


Dynamic Wrinkles

Wrinkles (also known as "rhytids") are lines that form in the skin. They can be broken down into a dynamic component and a static component. Younger patients tend to have only dynamic wrinkles. Older patients tend to have both dynamic and static rhytids.

Dynamic rhytids are the wrinkles that form when underlying muscles contract. On the face, these wrinkles form with facial expression and may create the appearance of tension, stress, fatigue, and/or age. These wrinkles form in the same location with each muscular contraction. In youth, these lines disappear completely when the muscle is relaxed.

By relaxing underlying muscles, Botox helps to diminish dynamic wrinkles. Three common areas for Botox injections are the frown lines, forehead lines, and Crow's feet.

Static Wrinkles

Static wrinkles are wrinkles that are apparent at rest (no facial muscle contractions). They result from years of muscle contractions and arise from dynamic wrinkles that have deepened and become persistent.

In general, Botox is most helpful for dynamic rhytids and filler agents are most helpful for static rhytids. By relaxing underlying muscles, Botox helps to diminish or eliminate dynamic wrinkles. When fillers are injected into static wrinkles, these products provide a volumizing effect which lifts and spreads the skin resulting in wrinkle reduction or elimination.

Botox is not as helpful for static wrinkles because they are present even when muscles are relaxed. However, it may mildly help static rhytids because all muscles have a chronic tone, even at rest. By relaxing the resting tone, Botox may mildly improve static rhytids. Regular Botox treatments may help prevent the progression and deepening of static rhytids by reducing the number of muscle contractions exerted on the overlying skin.
