The Zit Zapper booster is a cortisone injection that dramatically decreases the inflammation the occurs in a larger cystic-type of a pimple or cystic nodules. This type of pimple can become quite large and can also be quite painful. Cortisone is often used to bring down the level of inflammation for everything from insect bites to inflamed joints. Cortisone reduces inflammation and therefore helps a pimple to decrease in size and become far less painful in just a few hours.
