The present invention relates to a current stimulator and a control method thereof.

By flowing a microcurrent to the skin, the face or the like is massaged or pain is reduced. In particular, the collagen layer in the skin is stimulated to improve wrinkles or toning the skin.

In general, human body efficacy using microcurrent is known to promote ATP (adenosine triphjosphate) production, relieve delayed muscle pain (DOMS), promote waste discharge, promote fracture and wound recovery, antibacterial function, skin toning, wrinkle improvement, etc. . Then, by stimulating the skin coated with the lotion or the cosmetic cream with a microcurrent stimulator, an effective component of the lotion or the cosmetic cream can penetrate deeper into the skin.

While beauty is very important and modern people are very busy, they need microcurrent stimulators that can be used easily whenever and wherever they are.However, conventional microcurrent stimulators are bulky, portable, and can be used anytime, anywhere. It is inconvenient to use every time.

Therefore, there is a need for a microcurrent stimulator to be used in connection with a mobile phone, which is almost always a modern item.

That is, when stimulating the skin with a microcurrent stimulator, the applied electrical stimulation signal may vary depending on the intended use, which may be controlled through an application program embedded in a portable terminal device such as a smartphone.

For example, when using for the purpose of skin penetration of the active ingredient by iontophoresis, a direct current or ultra low frequency signal is applied, but when a lifting effect is expected, a pulse wave of a short period should be applied. In addition to the wave type, the frequency, time of use, voltage, and current must be changed depending on the application. This function can be enabled by controlling the output signal of the earphone through an application program embedded in the portable terminal device.

If the microcurrent stimulator is controlled by the earphone output signal through the built-in application of the mobile terminal device, for example, a store that distributes an application (application) when a new type of stimulus signal is developed (for example, an app). Store and Play Store) can be installed only through the application update process, there is little advantage of the post-management burden of the supplier, the user can easily experience a new type of stimulation when using the micro-current stimulator There is this.
