  1. PREP: Refresh and disinfect your eye area with Easy on the Eyes Calming Mist to create the perfect canvas. Pro-tip: for best results, apply liner before other eye makeup for easy touch-ups.
  2. POSITION: Begin by holding the liner in your dominant hand at a 45° angle from your eye
  3. LINE: Starting from the middle, close your eyes and draw outward to create desired shape, then connect the inner corner to middle. Pro tip: Re-dip between applications for smooth coverage.
  4. SET: Let liner dry for 30 seconds before applying the rest of your eye makeup—this step is key. Finish with another light mist of Easy on the Eyes to keep your eyes refreshed all day
