    摘要： A skin cleansing device has a base body and a removable cleansing head. The base body houses a vacuum pump and has a mount for connecting to the removable cleansing head. The mount has an opening into the base body and a support surface. The removable cleansing head has a collection portion and a mounting portion. The collection portion defines an inlet and an internal cavity. The mounting portion has a stem defining a channel fluidly connected to the internal cavity. The cleansing head is removably connectable to the base body with the stem being configured to be received in the opening of the mount. The vacuum pump is configured to generate a fluid flow through the internal cavity and the channel into the base body such that a suction force is generated at the inlet.
