It was found that the electrolyzedreduced water is advantageously e#ective in preventing oxidation of fish-lipid. Daily bathing in the water for , months decreased ORP (oxidation-reduction potential) and improved the elasticity of the skins. The water would contribute to suppression of oxidation/aging of the skin. Moreover, treatment of bleached hair by the water resulted in improvement in fluency and gloss. We can expect, therefore, that fresh hot spring water has same reductive characteristics as that of the electrolyzed-reduced water.
