1. Using the Short Edge of the tool, sweep along the lower lip line and upward, just past the smile line. Use the index finger of your opposite hand to anchor.
2. With the same edge follow along the upper lip line and past the smile line, pulling up and out, indenting the tool slightly over the smile line.
3. Stabilize the skin with two fingers. Using the Comb Edge like a pencil eraser perpendicular to the smile line, apply a small amount of friction by moving it back and forth over the line.
