Antioxidant Activity of Hydrogen Water Mask Pack Composed of Gel-Type Emulsion and Hydrogen Generation Powder.

Abstract

Hydrogen-generating powders were synthesized from zinc carbonate precursors at temperatures ranging from 400 to 700°C under a hydrogen atmosphere. Dissolved hydrogen concentrations were tracked over time using a dedicated meter. Antioxidant capacity was assessed via Oyaizu's method, hydroxyl radical scavenging rate, and ferric reducing antioxidant power (FRAP). A facial mask pack was then formulated by combining the optimized powder with a gel-type emulsion. In a clinical evaluation, participants using the hydrogen mask pack showed an 18.41% increase in skin density after 4 weeks, compared to 9.93% in the control group using a commercial product. The greater improvement in skin density observed in the experimental group was attributed to the capacity of molecular hydrogen to support recovery of the denatured outer skin layer.

Mechanism

Molecular hydrogen is proposed to scavenge hydroxyl radicals and support structural recovery of the denatured skin layer, thereby contributing to increased skin density.
