A diaphragm bottle pump system for dispensing a personal care product includes a bottle, a pump body, and a plurality of valves. The bottle holds the product. Further, the pump body includes a lower pump body and an upper pump body that define a diaphragm chamber therebetween that is acted on by a diaphragm. A first valve allows the product to pass from the bottle to the diaphragm chamber and prevents the product from passing to the bottle from the diaphragm chamber. A second valve allows the product to pass from the diaphragm chamber to an outside of the system and prevents the product from passing to the diaphragm chamber from the outside of the system. Additionally, a third valve allows air to pass from the outside of the system to the bottle and prevents the air from passing to the outside of the system from the bottle.
