    Abstract: A gas permeable layer capable of supplying hydrogen includes a thin layer, encapsulating a hydrogen production formula. An outer side of the thin layer is airtight. An inner side is air-permeable. An inner side surface has a plurality of small holes. The thin layer can be a single layer or a composite layer. The hydrogen production formula does not dissipate. The hydrogen production formula absorbs moisture in the air or liquid water, thereby generating hydrogen. The hydrogen is released onto the skin and into the human body through the small holes. The hydrogen production formula includes metal peroxides, metal hydroxides, or metal hydrides and aluminum powder, or microsilica. The gas permeable layer can be used in sanitary products including eye masks, mouth masks, face masks, cosmetic facial masks, bras, pasties, nursing pads, sanitary napkins (towels), diapers, panty liners, wound dressing, woundplasts, bandage gauze, decubitus pads.
