A tissue retraction system that allows aeration in a skinfold of a patient needing medical attention may include a flexible frame having a defined body shape comprising an internal facing surface configured to face a crease in the skinfold, an external facing surface opposite the internal facing surface configured to face outwardly and away from the patient, a first tissue facing surface, and a second tissue facing surface opposing the first tissue facing surface. Each of the first and the second tissue facing surfaces may be configured to engage against opposing sides of the skinfold.

A hydrogen-supplying breathable layer in the present disclosure comprises: a thin layer wrapping a hydrogen-producing formula inside, having an airtight outer side as well as an air-permeable inner side on which a plurality of micro pores are opened and featuring a monolayer or a composite layer; a hydrogen-producing formula wrapped inside the thin layer and not dissipated but absorbing moistures in air or liquid water for generation of hydrogen; hydrogen permeating a plurality of micro pores and released to skin and intra-corporal parts. The hydrogen-producing formula in the hydrogen-supplying breathable layer comprises metal peroxides (metal hydroxides or metal hydrides) and aluminum powders (or silica powders); the breathable layer is applicable to a dressing pack or other sanitary paraphernalia in daily lives for relieving non-bacteria inflammations and promoting health care effects.
