TL;DR

Special water treated with electricity and filtered can act like natural hot spring water to potentially slow skin aging.

Key Finding

Electrolyzed-reduced water lowered skin oxidation-reduction potential in a manner similar to natural hot spring waters with antioxidant properties.

Summary

Researchers created a special type of water using electrolysis (passing electricity through water) combined with filtration. This water had antioxidant properties (meaning it could resist damage from oxidation, a natural aging process). When people bathed in this treated water, it lowered the oxidation level of their skin in a way similar to bathing in natural hot spring water. The study suggests this artificially created water might help slow skin aging and oxidative damage.

Practical Takeaway

This small human study suggests electrolyzed-reduced water may have skin benefits comparable to therapeutic hot spring bathing, though the study did not report sample size or duration details, limiting how much we can conclude about its real-world effectiveness. More rigorous testing with larger groups and longer observation periods would be needed to confirm whether these effects translate to meaningful anti-aging benefits.

Abstract

Water-electrolysis with ion-exchange membranes followed by passing through ac- tivated carbon filter conducted to produce electrolyzed-reduced water that has neutral and reductive characteristics. In addition, the electrolyzed-reduced water was also confirmed characteristic of antioxidative activity. Bathing in the electrolyzed-reduced water lowered the ORP (oxidation-reduction potential) of human skin, as same as that in hot spring waters with reductive characteristic. Therefore, the electrolyzed-reduced water was expected to have a function of depressing the oxidation or aging of human skin. We concluded that the electrolyzed-reduced water is applicable to artificial hot spring water. Furthermore, we also suggested that the system have changed the oxidative characteristic of hot spring waters by addition of disinfectant such as chlorine compounds into the reductive characteristic.
