However, usually low, medium and high frequencies have their own advantages and disadvantages.
Low-frequency waves have the advantage of having a strong ability to move muscles and a strong sense of stimulation, but they are subject to strong resistance on the skin, making them prone to strong tingling and pain, and some people are unable to endure the stimulation. Not a few. Also, due to the high resistance of the skin, the electric current can only enter a few millimeters below the skin and does not reach the deep muscles, making it impossible to sufficiently move the important muscles. Furthermore, if the intensity is increased in order to strengthen the stimulation, strong pain will occur in the skin.
On the other hand, medium frequencies have shorter wavelengths, lower skin resistance, and less burden on the skin than low frequencies. The electric current can reach up to 2-3 centimeters under the skin. However, the sensation of bodily sensation is felt weaker than that of the low frequency.
The wavelength of the high frequency wave is even shorter, the skin resistance is even smaller than that of the medium frequency wave, and the current can reach more than 10 cm under the skin and reach the vascular tissue, thus dilating the blood vessels and promoting blood circulation. You can get the improvement effect of stiff shoulders and stiff back. However, the sensation of bodily sensation is weaker than that of medium frequency.

The low-frequency beauty device provided by Patent Document 1 uses a single low-frequency wave, which places a heavy burden on the user's skin and does not reach deep muscles. Also, if the output is increased to increase the effect, the nociceptors in the skin will be stimulated, causing intense pain. Furthermore, since the electric stimulation signal is regular and monotonous, the user tends to become accustomed to the stimulation, which leads to a decrease in motivation to use.
In the beauty device provided by Patent Document 2, the duty ratio is changed to change the intensity of the stimulus, so that a soft feeling can be obtained. Since it is small, it does not reach deep muscles and blood vessels, and because it uses alternating current, it cannot be made compact and portable, making it easy to feel inconvenient to use. .
In the beauty device disclosed in Patent Document 3, by increasing the amount of electrical stimulation while decreasing the peak current value, it is possible to relieve the discomfort of the user, but the electrical stimulation signal is regular. Since it is monotonous, there is a problem that the user becomes accustomed to the stimulus, which leads to a decrease in feeling of use, and loses the motivation to use it continuously for a long time. Furthermore, since an alternating current is used in the same manner as in Patent Document 2, there remains the problem of lack of convenience in use.
