What do studies say about Hautalterung Training?

The provided context does not contain direct studies on 'skin aging training'. Some DNA-related entries (e.g., COMT, TAS2R38) mention indirect links to stress or diet, but not to exercise. Generally, moderate endurance training is known to improve blood flow and oxygen supply to the skin and may reduce oxidative stress, which could theoretically counteract skin aging. However, robust human studies specifically demonstrating a causal effect of training on collagen or glycation markers are lacking. The evidence level is therefore 'mixed': there are mechanistic hints but no strong clinical confirmation. Consumers should be skeptical of exaggerated marketing claims. A balanced lifestyle with exercise, sun protection, and good nutrition remains the safest approach.
