Description

Skin massage device {Skin massage device}

The present invention relates to a skin massage device, and more specifically, a user can not only perform a skin massage by himself, but also receive a skin massage by another person, and when receiving a skin massage by another person, physical contact between the user and another person is prevented. It relates to a skin massage device capable of eliminating a user's discomfort due to body contact.

In recent years, interest in skin beauty has been increasing day by day, and accordingly, cosmetics with excellent skin protection effects are attracting attention.

In general, in order to absorb ingredients useful for the skin into the skin, a method such as tapping the face with a hand or using a vibrating device is sometimes used.

In addition, the skin is massaged and restored after a procedure related to skin treatment.

Recently, ion massage devices for skin care that allow cosmetics to permeate well into the user's skin have been sold. An ion massage device for skin care is in contact with the skin and current flows, infiltrating negative charges into the skin to ionize the skin so that cosmetics penetrate well into the skin.

A conventional ion massage device for skin care includes a housing made of a first electrode member made of a conductor that serves as a handle that the user holds, and a second electrode member made of a conductor and in contact with the skin in a state insulated from the first electrode member. And, when DC power is applied to the first electrode member and the second electrode member, and the second electrode member is in contact with the user's skin while holding the first electrode member by hand, current flows through the skin and penetrates negative charges into the skin will make

However, when a conventional ion massager for skin care is massaged by another person, another person grabs the handle and contacts the first electrode member, and the second electrode member contacts the user's skin in an open state in which current is not conducted. Therefore, physical contact between other people and users is essential to form a closed loop between other people, users, and devices. there is.
