About Your Skin | The Wrinkle Spectrum

Wrinkles come in all shapes and sizes. Doctors often rely on a classification system developed by Thomas Fitzpatrick MD, Ph.D,4 to describe them:

Class I – Fine wrinkles

Class II – Fine-to-moderately deep wrinkles and a moderate number of wrinkle lines

Class III – Fine-to-deep wrinkles, numerous wrinkle lines, and redundant folds possibly present

In addition, you may hear your doctor talk about dynamic vs. static furrows. Dynamic furrows appear with muscle movement, e.g., the lines around a teenager’s eyes when he or she smiles. Static lines are there with or without muscle movement. Eventually dynamic lines become static.
