TL;DR
Bathing in hydrogen-infused warm water improves blood circulation in fingertips and skin moisture, and more effectively cleans out skin pores compared to regular warm water.
Key Finding
Hydrogen-infused warm water removed 2.30 to 4.47 times more keratin plugs from skin pores compared to regular warm water, and increased capillary blood flow by approximately 20% more than regular warm water alone.
Summary
This study tested whether warm water infused with hydrogen gas (created through electrolysis) could improve skin health better than regular warm water. Researchers had healthy volunteers soak their hands in hydrogen water or regular warm water, then measured blood flow in tiny blood vessels, skin moisture, and how well each water type cleared out keratin plugs (small protein blockages in pores). Hydrogen water increased blood flow by about 20% more than regular warm water and removed 2-4 times more keratin plugs from facial pores, though the effect was stronger on cheeks than on nostrils.
Practical Takeaway
This small study in healthy people suggests hydrogen water may have modest benefits for skin cleansing and blood flow, but the study did not report sample size or duration details, making it difficult to assess reliability. The improvements were measured in a laboratory setting on healthy volunteers, so it's unclear whether these effects would be noticeable in real-world use or would benefit people with skin conditions. More rigorous research with larger groups and longer follow-up is needed before drawing conclusions about practical benefits.
Abstract
Biomedical properties of hydrogen water have been extensively investigated, but the effect of hydrogen on good healthy subjects remains unclear. This study was designed to explore the hygiene improvement by electrolytically generated hydrogen warm water (40°C) on capillary blood streams, skin moisture, and keratin plugs in skin pores in normal good healthy subjects with their informed consents. Fingertip-capillary blood stream was estimated after hand-immersing in hydrogen warm water by videography using a CCD-based microscope, and the blood flow levels increased to about 120% versus normal warm water, after 60 minutes of the hand-immersing termination. Skin moisture of subjects was assessed using an electro-conductivity-based skin moisture meter. Immediately after taking a bath filled with hydrogen warm water, the skin moisture increased by 5-10% as compared to before bathing, which was kept on for the 7-day test, but indistinct, because of lower solubility of hydrogen in 'warm' water than in room-temperature water. Cleansing of keratin plugs in skin-pores was assessed by stereoscopic microscopy and scanning electron microscopy. After hydrogen warm water bathing, the numbers of cleansed keratin plugs also increased on cheek of subjects 2.30- to 4.47-fold as many as the control for normal warm water. And areas of cleansed keratin plugs in the cheeks increased about 1.3-fold as much as the control. More marked improvements were observed on cheeks than on nostrils. Hydrogen warm water may thoroughly cleanse even keratin-plugs of residual amounts that could not be cleansed by normal warm water, through its permeability into wide-ranged portions of hair-pores, and promote the fingertip blood streams more markedly than merely through warmness due to normal warm water.
