Whether you use a cartridge, safety or straight razor it’s wise to keep a styptic pencil or pack of styptic matches into your bathroom cabinet.
Styptic pencils or matches are made from potassium alum and will stop minor bleeding in seconds. Simply wet the head of the match or pencil and dab onto the nick, it will sting slightly but you won’t need tissue stuck to your face or legs for hours to stop any bleeding.
If using styptic matches, throw away after a single use. If using a styptic pencil dry after use to stop it dissolving.
