Spots are caused by blocked pores which get clogged up and then bacteria get stuck under the surface and cause the area of skin to inflame and thus cause a spot.
To get rid of spots there are a number of antiseptic creams on the market that will reduce the inflammation and get rid of the bad stuff like the bacteria and germs inside a spot. This will speed up the time a spot takes to disappear.
You can also use toothpaste that has Bicarbonate of Soda, this will dry out and kill the puss inside the spot and speed up the recovery time and make it heal faster.
As with most things, prevention is better than cure and many spots are caused by a bad diet or just by unfortunate circumstances. Puberty as well as a polluted atmosphere and stress can cause skin issues also.

Even though they are often called 'liver spots', they are usually only a sign of sun damage at some point in our lives (which becomes much more obvious as we age).  If it is very dark and/or unusually shaped (or changing), or you are very concerned, have a dermatologist look at it. 

Not necessarily. Age spots are brown, they used to be called liver spots, but are caused by years of exposure to the sun. They can appear as early as 30.
