Typically you should not "pop" your pimples
This allows bacteria
to enter the break in the skin and increase chances of infection. If you must pop a pimple, sterilized the area with rubbing alcohol
, lance the pimple at the base with a sterile needle and push out the pus
. Cover the area with a bandage and possibly neosporin to prevent infection.
