What to watch with CLOCK and skin aging?

The CLOCK gene variant is linked to circadian rhythm regulation. Disrupted circadian rhythms can affect skin aging by impairing collagen synthesis and increasing oxidative stress. However, evidence for individual CLOCK variants on skin aging is mostly mechanistic and not robust enough for personalized advice. Therefore, focus on general strategies: maintain consistent sleep patterns, use sun protection, eat an antioxidant-rich diet (e.g., vitamins C and E), and stay hydrated. A single DNA test should not drive major changes; lifestyle and environmental factors are more influential. If you have specific skin concerns, consult a dermatologist. The effect of one SNP is small, and consumer tests often overstate implications.
