Topically Applied Molecular Hydrogen Normalizes Skin Parameters Associated with Oxidative Stress: A Pilot Study.

Area of Science:

• Dermatology
• Biochemistry
• Cosmetic Science

Background:

• Oxidative stress contributes to skin aging and damage.
• Molecular hydrogen (H₂) exhibits antioxidant and anti-inflammatory properties.
• Topical H₂ is a novel approach to address skin concerns.

Purpose of the Study:

• To evaluate the efficacy of hydrogen-rich water treatments on objective skin parameters in healthy adults.
• To assess the impact of topical H₂ on oxidative stress and skin barrier function.
• To explore the potential of H₂ in cosmetic and preventive dermatology.

Main Methods:

• A pilot clinical study involving 15 healthy adult participants.
• Four weeks of topical treatment with hydrogen-rich water.
• Quantitative assessment of skin parameters including pore size, pigmentation, wrinkles, and biological skin age before and after treatment.

Main Results:

• A statistically significant reduction in pore visibility was observed, especially in younger individuals.
• Trends toward improvement were noted in porphyrin levels, pigmentation, wrinkle severity, and biological skin age.
• The treatment was well-tolerated with no reported adverse effects.

Conclusions:

• Topical hydrogen-rich water treatments show promise for improving objective skin parameters.
• Further controlled studies are necessary to confirm efficacy and understand mechanisms.
• H₂ holds potential for cosmetic and preventive dermatological applications.
