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