How are FOXO3 and skin aging related?

The provided contexts contain no specific information on FOXO3 and skin aging. In general, FOXO3 is a transcription factor involved in cellular stress resistance, DNA repair, and longevity. In skin, FOXO3 regulates antioxidant enzymes (e.g., superoxide dismutase, catalase) and supports collagen maintenance, thereby protecting against photo-oxidative stress and premature aging. Variants in FOXO3 (e.g., rs2802292) have been associated with reduced wrinkle formation and better skin elasticity in population-based studies. The evidence is primarily epidemiological and mechanistic, not from randomized controlled trials. Since the given contexts lack FOXO3 data, this answer is based on general scientific knowledge. The evidence level is therefore considered unclear.
