Active hydrogen is the strongest known antioxidant. The apparatus successfully uses its biophysical properties. As the smallest and lightest of the elements, it easily penetrates deep into the skin structures, where it binds with the most harmful free oxygen radicals. Effectively neutralizes them, depriving the skin of harmful properties. It is then excreted from the body in the form of water. The strong antioxidant properties of hydrogen ions make it unmatched in the fight against radical skin aging. It almost literally “sweeps” free radicals out of it. It slows down and even inhibits the aging process at the cellular level. Hydrogen purification is undoubtedly the best proposition for people exposed to stress and environmental pollution.
