Bunny lines are the oblique lines on the sides of the nose that you see when you scrunch your nose and sometimes when you squint. These lines are caused by contraction of the nasalis muscle and can be treated with Botox® or Dysport®. This is considered “off-label” use.
Deep nasolabial folds which are sometimes referred to as “parentheses lines” are related to drooping of the mid face over time and can also have a genetic component. They can be softened by treatment with injectable filler or Sculptra®. The FDA has approved multiple hyaluronic acid Juvederm® and Restylane® brand fillers and Sculptra® for moderate to severe, shallow to deep facial wrinkles, such as the nasolabial folds.
