It is not possible to remove a pimple overnight. However, a person can reduce the appearance of pimples by lowering inflammation in the area with ice wrapped in a cloth and applying a 2% benzoyl peroxide product to the pimple. For whiteheads, a person can apply a warm compress to the area for 10 minutes a few times a day.
A person should not pop, squeeze, or pick at pimples to get rid of them, as this can cause bleeding, scarring, and increase a person's chance of infections.
