Myths vs facts: Fitness | LifestyleCheck and skin aging

Myth: A fitness or lifestyle test can precisely show how your exercise routine affects skin aging. Fact: Available tests (e.g., DNA longevity tests) typically measure single genes like ADIPOQ or IL-1B, whose effects on skin aging are small and indirect. Mechanistic studies show that mechanical stress from exercise can trigger antioxidant defenses (PMC13093398), but no consumer test in the context directly measures this. Evidence is mostly mechanistic or from GWAS, not from clinical trials on skin aging. Therefore, a LifestyleCheck cannot reliably tell you how your fitness regimen impacts skin aging. General lifestyle factors (UV protection, diet, sleep) are better supported. Caution: do not overinterpret genetic test results – they are not diagnostic.
