The tape that I have found most suitable, as it is simple to use, hypoallergenic, and light, is 3M Micropore tape, which can be bought from most drugstores. To help make the tape easier to remove in the morning, gently press the tape against the back of your hand a couple of times to remove some of the glue before applying the tape to your face. All you need to do is tear off about 4 inches/10 cm of tape, fold a tab over at both ends to make removal easier in the morning, dry your lips, close your mouth, and gently place the tape horizontally over the lips.
