This question usually refers to (1) skin appearance and (2) “biological youth/energy.” Resveratrol intersects with aging biology through oxidative stress and inflammation pathways, but claiming it “rejuvenates” requires strong long-term human evidence.\n\nSkin: topical resveratrol may support antioxidant defenses; some studies report modest improvements in redness, elasticity, or photoaging signs, highly dependent on formulation, concentration, and stability.\n\nOral use: discussions focus on metabolic/vascular markers rather than visible “youth.” Results are mixed across trials.\n\nPractical framing: resveratrol won’t reverse aging without fundamentals—sun protection, sleep, adequate protein, resistance training, and not smoking. Consider it a supportive layer, not the core strategy.
