A device for treating cutaneous blemishes and dermatologic diseases that includes an application bell operatively connected to a feeding assembly is described. The bell is shaped to be removably leant on a cutaneous surface to be treated and with which it defines a treatment chamber. The feeding assembly includes, in its turn, a pump which realizesin the treatment chamberan environment having a pressure lower than the atmospheric pressure, and an oxygen delivering device activated subsequently to the pump, to deliverin the treatment chamberan oxygen flow. The feeding assembly provides for a controlling unit to selectively activate, in time sequence, the pump and the oxygen delivering device.

A lip enhancement and enlargement device includes a suction element and a lip shaper coupled to the suction element. A lip shaper may include one or more features that allow the device to shape and contour lips. A lip shaper may include one or more contouring elements that change the shape of an upper lip, for example. A lip shaper may also include shaping and contouring elements that form a fuller, unitary lip lobe or two fuller, lip lobes. Lip enhancement and enlargement kits and methods are also disclosed.

A ventilation switching structure includes a valve, a switching cylinder, and a knob. The valve includes a receiving room, a main tube and branch tubes. The main tube is connected with a negative pressure instrument and connected to the receiving room. The branch tubes are located on two sides of the main tube. The switching cylinder is rotatably disposed in the receiving room and includes a main channel, multiple lateral channels, and a blocking wall. The lateral channels communicate with the main channel and are disposed on a side of the blocking wall at intervals. The knob is connected on the switching cylinder. The knob is capable of rotating the switching cylinder to make the blocking wall optionally block one of the branch tubes so as to accomplish the object of ventilation switching.

An elongated massage cup includes an elongated cup having an open side and a closed side. The closed side includes a valve that connects to a pump. The pump is configured to connect to the valve and evacuate air from the elongated cup when the open side of the cup is placed against a portion of a user's body, thereby creating an airtight pocket between the elongated cup and the user's body and a suction effect against the user's skin.
