What is the difference between a booster and a personal care pad?

Booster pads have a flow-through design that allows the pad to fill to capacity first and then pass additional fluid to the host (primary) garment. Booster pads are placed inside any disposable undergarment with a moisture proof backing. A Personal Care pad has a moisture proof backing and is meant to be worn in regular underwear. It should not be used as a liner inside a host garment, as the moisture proof backing would not allow the fluid to flow through, it will actually cause it to run out of the product and leak.
