Abstract

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.

Claims (27)

1. A skin care kit, comprising:

a skin care composition; and

a skin cleansing device, comprising

a base body housing a vacuum pump and comprising a mount, the mount comprising an opening into the base body and a support surface; and

a plurality of disposable cleansing heads comprising a collection portion and a mounting portion, the collection portion defining an inlet and an internal cavity and the mounting portion comprising a stem defining a channel fluidly connected to the internal cavity,

wherein each of the plurality of disposable cleansing heads is removably connectable to the base body with the stem being configured to be received in the opening of the mount, and

wherein 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 of a cleansing head connected to the base body,

wherein the skin care composition is configured to prepare the skin for use with the skin cleansing device.

2. The skin care kit of claim 1 , wherein the plurality of disposable cleansing heads comprises at least a first cleansing head and a second cleansing head.

3. The skin care kit of claim 2 , wherein the inlet of the first cleansing head is larger than the inlet of the second cleansing head.

4. The skin care kit of claim 3 , wherein the second cleansing head comprises an outer housing and an inner nozzle, wherein the outer housing is relatively movable with respect to the inner nozzle, and wherein the inner nozzle defines the internal cavity and the inlet.

6. The skin care kit of claim 1 , wherein the disposable cleansing head comprises a filter element positioned between the internal cavity and the channel.

7. The skin care kit of claim 1 , wherein the disposable cleansing head comprises at least one protrusion on the stem and the base body comprises a spring clip configured to mate with the at least one protrusion to secure the disposable cleansing head to the base body.

8. The skin care kit of claim 1 , further comprising a sealing element positioned on the stem of the disposable cleansing head.

9. The skin care kit of claim 1 , further comprising an O-ring positioned on the stem.

10. The skin care kit of claim 1 , wherein the disposable cleansing head collects the unwanted material (e.g., dirt, debris, cleanser, blackhead, sebum, etc.) in the collection portion preventing the contamination of the base body and its internal components, wherein additional cleaning or sanitizing of the base body is not required.

11. The skin care kit of claim 1 , wherein the plurality of disposable cleansing heads further comprises a third cleansing head formed as a dermaplaning cleansing head, wherein the dermaplaning cleansing head includes an inlet having one or more air channels that are formed inside of an elongated perimeter wall.
