Description

Technical Field

[0001] The present disclosure relates to a skin beauty handpiece mainly used in dermatology hospitals and esthetic clinics, and a skin beauty multi-system including the same.

Background Art

[0002] As humans age, the facial muscles lose elasticity, forming wrinkles or sagging skin. With the development of the beauty industry, beauty devices related to skin care have been developed to prevent visible wrinkles and sagging of the skin (especially the face).

[0003] Beauty devices are used as devices that can not only increase the production of collagen and elastic fibers by electrical stimulation and regenerate skin cells, but also make the skin healthy and elastic through cell regeneration and increased blood flow to perform skin protection and skin care.

[0004] Beauty devices mainly use a handpiece that is easy to hold. Such a handpiece has a ball-shaped rotating body rotatably coupled thereto, and an electrical stimulation generating unit is formed inside the handpiece and is structured to transmit electrical stimulation to a pair of roll-shaped rotating bodies.

[0005] The above information can be provided as background art (relevant art) for helping the understanding of the present disclosure. No claim or determination is made as to whether any of the above contents can be applied as prior art in relation to the present disclosure.

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, when performing skin massage using a conventional handpiece, there is a risk that the rotating body, which is the oscillator, may shift its axis of rotation during the rolling process. In particular, if the axis of rotation shifts at night, there is a risk that the transmission of low-frequency current may be interrupted or its intensity may change.

[0008] Furthermore, when performing skin massage using a handpiece, there is a risk that the skin may be stretched too much or stimulated insufficiently as the roller-type rotating body rolls along the skin.

[0009] Furthermore, when performing skin massage using a handpiece, the arm with a roll-type rotating body is fixed to the main unit, which limits how closely it can adhere to the user's skin. In particular, excessive or insufficient skin contact can prevent efficient massage.

[0010] Furthermore, while multiple handpieces are required for skin treatment or cosmetic procedures in dermatology hospitals or clinics, cosmetic systems that include handpieces are equipped with only two or three handpiece stands. This limitation of using only two or three handpieces may make it difficult to quickly and proactively address a variety of skin conditions.

[0011] The technical problems that this specification seeks to solve are not limited to those described above, and other technical problems not mentioned above will be clearly understood by those with ordinary skill in the art to which the present invention pertains from the following description.
