Study at a glance
Human
Human participants studied for skin, wound and aging research. See eligibility criteria in the linked full text.
Full text reports H₂ dissolved in drinking water. Detected intervention quantities or schedules: 0.018 ppm, 1.3 ppm, 0.55 L/min. · H₂-related quantities reported in the intervention passages: 0.018 ppm, 1.3 ppm, 0.55 L/min. Values are not combined across different experimental arms.
0.55 L/min
Article-reported result excerpt (24 words maximum): “Statistical analysis was performed using Student’s t -test, and the significant differences are defined as p < 0.05.” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.
Human evidence; design, sample size and comparator limit interpretation. Funding or grant information is reported in the full article. The article declares no conflicts of interest.

Some editorial classification fields are still pending. The source-reported outcomes and result are shown below; Hydrogenology does not infer a positive or negative signal from prose automatically.
Methods
Human participants studied for skin, wound and aging research. See eligibility criteria in the linked full text.
Human study; group or assay counts reported in the full text include n=12, n=10.
0.55 L/min
Full text reports H₂ dissolved in drinking water. Detected intervention quantities or schedules: 0.018 ppm, 1.3 ppm, 0.55 L/min.
H₂ dissolved in drinking water — H₂ only unless the full text explicitly reports oxygen co-delivery.
H₂-related quantities reported in the intervention passages: 0.018 ppm, 1.3 ppm, 0.55 L/min. Values are not combined across different experimental arms.
Control or comparison condition reported in the full article; see the linked methods for arm-specific details.
Outcomes and reported result
survival or mortality, clinical symptoms or functional scores, tumor growth or cancer markers, inflammation and cytokines, oxidative-stress and antioxidant markers, apoptosis or cell injury
