Abstract
Excessive exposure to ultraviolet (UV) radiation is a major factor in the development of skin photoaging wrinkles. While current treatments can slow the progression of photoaging, it is very difficult to achieve complete reversal. This study introduces galvanic cell microneedle (GCMN) patches with magnesium-containing bipolar electrodes. These patches operate through a galvanic cell mechanism, generating microcurrents and releasing hydrogen gas and magnesium ions via a redox reaction. The combination of hydrogen's antioxidant and anti-inflammatory properties, microcurrent-induced stimulation of cell migration, and magnesium's promotion of angiogenesis and macrophage M2 anti-inflammatory polarization synergistically works to reverse photoaging wrinkles and rejuvenate the skin. Furthermore, this work examines how GCMNs may influence the transforming growth factor-β/Smad (TGF-β/Smad) pathway. This approach shows promise for advancing research and development in the field of medical cosmetology.
