**What is Biocurrent?**

In fact, biocurrent is electricity naturally present in the human body. A healthy body has a good electrical potential balance, and the human body functions from nerves to cells based on this electrical potential balance. Biocurrent is very familiar; mobile phones, for example, use biocurrent naturally generated in the human body for screen operation, which is one of the bio-technologies.

While biocurrent naturally occurs in the human body, 'TROMATZ' technology is characterized by its unique ability to generate biocurrent through electronic technology and externally adjust the body's electrical potential balance.

Currently, we are researching and developing biocurrent beauty devices that simultaneously cleanse and regenerate skin and improve the penetration rate of lotions and hair growth products, biocurrent hair growth brushes, and medical devices that improve rhinitis inflammation, under a global system spanning Japan, the U.S., and Korea.

'TROMATZ' rhinitis treatment device. It suppresses bacteria and improves inflammation.

**Global Network**
