How to Line Lips Perfectly
Sharpen the pencil first. Start at the cupid's bow. Draw short strokes outward. Line the lower lip center outward. Connect at the corners. Fill in lightly toward the center. Blend with your finger. Apply lipstick over the top. For fullness, line just outside the natural edge. Keep it subtle. Apply Slim Lip Pencil in a thin first layer for full pink impact. Add a light second layer for extended wear. Apply Slim Lip Pencil with careful, even strokes for the most natural pink effect. Build the color slowly. For precision with Slim Lip Pencil, use small strokes and build the pink color gradually. Less product looks better. Apply Slim Lip Pencil in a thin first layer for full pink impact.
