化妝水泵係一種透過使用真空分配特定數量嘅產品嘅裝置. 当泵嘅執行器被按下時, it produces approximately 2cc of product. These devices, unlike non-lotion pumps, do not become clogged with product. Their outer shell also allows air to flow, creating pressure inside the bottle without drying it out. They are suitable for use in lotions, 洗髮水, and conditioners.
