Coronal lift for frown lines
First, you have to determine if the lines you are talking about are static or dynamic or both. Carefully anatomical analysis will determine the cause. Treatment should be targeted to the specific anatomical cause. Some dynamic lines can be treated simply with Botox, while others require surgical intervention. Coronal incision lifts do have a place and purpose but they cannot be said to be more effective, or necessary, solely for frown or scowl lines.
