It is said that you should not squeeze a pimple as it can lead to scarring. If you must rid yourself of a pimple, it is best to prep yourself and the area first. To start, you will need to make sure your hands are clean; you want to avoid spreading more bacteria. Using a warm washcloth, open the pores by pressing it against your skin for a minute. Then, using a sterilized lancet (sharp bladed tool), slightly pierce the whitehead. Wrap your fingers in tissue and gently squeeze. Do not keep squeezing if nothing comes out on the first couple of tries; it is obviously not ready to be squeezed.
