First, allow a full beard to grow into several days of stubble. Shave the neckline under the jaw cleanly. Then shave a concave line on both sides if the upper lip that runs from the center under the nose, to the corners of the mouth. In the next step, shave a clean line that runs from the edges of the moustache, across the cheeks and along the inner edge of the side burns. Finally, shave around the mouth, across the upper and lower lip, leaving a center strip from the bottom lip to the chin.
