Lay opinion vs evidence: Hautalterung Training

Lay opinion often claims that exercise can prevent or reverse skin aging. The evidence is mixed. Moderate training improves circulation, reduces oxidative stress, and may boost collagen synthesis—all potentially beneficial for skin health. Some observational studies link regular exercise to better skin elasticity and thickness. However, rigorous human RCTs are scarce. Excessive endurance exercise can increase free radicals and cortisol, potentially accelerating aging. Genetics (e.g., collagen-related SNPs) also modulate individual responses. Conclusion: moderate exercise likely supports skin health, but it is not a proven anti-aging intervention. Evidence is primarily mechanistic and observational. Without personalized biomarkers (e.g., skin analysis, oxidative stress markers), recommendations remain generic. Beware of marketing hype.
