Hydrogen Microneedle Patch in Mice for Psoriasis

Microneedle-based hydrogen delivery reduces oxidative stress and inflammation in psoriasis, outperforming standard topical therapy.

In mice with psoriasis, transdermal hydrogen therapy delivered via microneedles outperformed calcipotriol cream, a standard topical treatment, by reducing inflammation, immune cell infiltration, and abnormal skin cell growth.

Researchers developed a new way to treat psoriasis (a chronic skin condition) by using tiny needles to deliver hydrogen-releasing powder directly into the skin. In mouse studies, this approach reduced skin inflammation and damage better than a standard psoriasis cream, by targeting two interconnected problems in psoriasis: oxidative stress (cellular damage from unstable molecules) and inflammation (the body's immune response gone wrong).

While this early-stage research in mice suggests hydrogen therapy may be a promising approach for psoriasis, it has not yet been tested in humans. The study demonstrates proof-of-concept for a new delivery method, but much more research would be needed before this treatment could be available to patients.

Psoriasis remains clinically incurable due to its complex etiology. Topical immunosuppressive therapies offer limited effectiveness partly because of poor skin permeability, and can cause severe side effects. To address these challenges, we developed a novel transdermal hydrogen therapy that…
