Is Skincare DNA useful for Sport?

The direct utility of 'skincare DNA' tests for sports is poorly supported by evidence. These tests typically examine genes related to collagen (e.g., COL1A1), antioxidant defense (e.g., SOD2), or UV sensitivity. For athletes, these could theoretically influence wound healing, sun protection, or connective tissue integrity, but the effect of single variants is small and heavily modulated by lifestyle (diet, training, skincare). Evidence is mostly mechanistic or observational; no robust sport-specific RCTs exist. Consumer tests often overstate single-SNP effects. Practical, evidence-based measures (adequate protein, vitamin C, sun protection, tailored skincare) are far more impactful. A DNA test may serve as a motivational nudge but should not replace professional advice. Safety note: Do not make diagnostic or treatment decisions based solely on such tests.
