  • Publication number: 20100112086
    Abstract: An electrolytically reduced water which consists of an alkali ion water prepared by ion exchange and has a dissolved hydrogen concentration of 0.20 ppm or above, an oxidation-reduction potential of ?150 mV to ?500 mV, and a hydrogen ion component of pH6.5-10.5 and which is quantitatively specified in the reducing power capable of inhibiting the oxidative deterioration of fat in the cutis through the elimination of active oxygen due to the characteristics of hydrogen, the oxidation-reduction potential characteristics of high reducing action, and alkaline characteristics and can activate the skin to inhibit the oxidative deterioration and suppress lumpy fat (cellulite).
