It improves skin damage and delivers hydrogen to the whole body, ultimately providing strong sulfide action.

Hydrogen Skin Care System (Direct Skin Penetration of Hydrogen)
Hydrogen Molecule penetrates the skin surface and produces semi-fluorine oxygen directly.

Hydrogen gas injection system (penetration of hydrogen gas through mucous membranes)
The mucosal absorption of hydrogen through breathing is not under the control of body borough Absorption rate is very high
