Step 4: Shaving Your Neck and Chin
To shave under your chin and your nick, shave from the bottom of your neck upwards. This will help prevent razor burn and ingrown hairs.
When shaving under your chin, pull the razor from your throat area toward your chin.
Remember, as you are shaving be sure to rinse your razor with warm water after every stroke or two to keep it from getting clogged with hair.
