Juncusol 7-O-glucoside is a stilbene glucoside derived from plants in the Juncus genus, such as those found in wetland environments. It is primarily used in biochemical research to study its antioxidant properties and potential anti-inflammatory effects. Preliminary studies suggest it may protect cells from oxidative stress, supporting applications in anti-aging skincare formulations, reducing redness, and soothing irritated skin. It also shows promise in promoting skin barrier function and hydration. However, its use remains in the research phase, with further cell and animal studies needed to confirm efficacy for cosmetic or pharmaceutical development.
